Run php Script Automatically on Windows

It is quiet often that we need to execute/run some php script on some time interval at server side. And that php scripts should run automatically on windows server. On internet you will many aps and cron job simulator for windows but they are not necessary.

U can simply run the task automatically with windows using "Task Scheduler". It is inbuilt in windows and very user friendly in use.

PHP files can easily be run on Command Prompt ( More details click here ).
           ex. C:\Path\to\php.exe -f "C:\Path\to\file.php"    
      where -f is file attribute - parse and execute file.

 If you wants to run script on windows hosting server then you can try creating a batch file script that runs instead. So, you would create a file called something like "myfile.bat" using Notepad, and you would use this code in that file:
C:\Path\to\php.exe -f "C:\Path\to\file.php"   
And you would use the Task Scheduler program to run the myfile.bat

To start the windows task scheduler - Start -> All Programs -> Accessories -> System Tools -> Task Scheduler.

Or type in search bar of windows : Task Scheduler.

Steps to Schedule PHP Script in Task Schedular
  1. Open Task Scheduler as shown above.
  2. In Task Scheduler, Click on "Action -> Create Task" from menubar.
  3. In "General" tab write "Name"- Name of Task and "Description" - Description for Task.



  4. In "Triggers" tab click on "New" and give triggering time as per requirement.



  5. In "Actions" tab click on "New" and select Action - Start Program (Default).
    And from browse button select your php.exe file from your php installed files.
    And in "argument" give file path with Option  ex. -f c:\pathToHtdocs\fileName.php (here -f is option).



  6. In "Conditions" tab you can set condition when to run task means about the your pc status like idle/on AC power, etc. I suggest you to leave it as default.



  7. In "Settings" tab you can specify some extra settings.  I suggest you to leave it as default.



  8. Finally As you done, Click on "Run" from "Action" to run it manually.


Command Line Options


Option
Long Option
Description
-a
--interactive
Run PHP interactively. For more information, see the Interactive shell section.
-b
--bindpath
Bind Path for external FASTCGI Server mode (CGI only).
-C
--no-chdir
Do not chdir to the script's directory (CGI only).
-q
--no-header
Quiet-mode. Suppress HTTP header output (CGI only).
-T
--timing
Measure execution time of script repeated count times (CGI only).
-c
--php-ini
Specifies either a directory in which to look for php.ini, or a custom INI file (which does not need to be named php.ini), e.g.:
$ php -c /custom/directory/ my_script.php
$ php -c /custom/directory/custom-file.ini my_script.php
If this option is not specified, php.ini is searched for in the default locations.
-n
--no-php-ini
Ignore php.ini completely.
-d
--define
Set a custom value for any of the configuration directives allowed in php.ini. The syntax is:
-d configuration_directive[=value]
# Omitting the value part will set the given configuration directive to "1"
$ php -d max_execution_time
-r '$foo = ini_get("max_execution_time"); var_dump($foo);'
string(1) "1"
# Passing an empty value part will set the configuration directive to ""
php -d max_execution_time=
-r '$foo = ini_get("max_execution_time"); var_dump($foo);'
string(0) ""
# The configuration directive will be set to anything passed after the '=' character
$  php -d max_execution_time=20
-r '$foo = ini_get("max_execution_time"); var_dump($foo);'
string(2) "20"
$  php
-d max_execution_time=doesntmakesense
-r '$foo = ini_get("max_execution_time"); var_dump($foo);'
string(15) "doesntmakesense"
-e
--profile-info
Activate the extended information mode, to be used by a debugger/profiler.
-f
--file
Parse and execute the specified file. The -f is optional and may be omitted - providing just the filename to execute is sufficient.
Note:
To pass arguments to a script, the first argument must be --, otherwise PHP will interpret them as PHP options.
-h and -?
--help and --usage
Output a list of command line options with one line descriptions of what they do.
-i
--info
Calls phpinfo(), and prints out the results. If PHP is not working correctly, it is advisable to use the command php -i and see whether any error messages are printed out before or in place of the information tables. Beware that when using the CGI mode the output is in HTML and therefore very large.
-l
--syntax-check
Provides a convenient way to perform only a syntax check on the given PHP code. On success, the text No syntax errors detected in <filename> is written to standard output and the shell return code is 0. On failure, the text Errors parsing <filename> in addition to the internal parser error message is written to standard output and the shell return code is set to -1.
This option won't find fatal errors (like undefined functions). Use the -f to test for fatal errors too.
Note:
This option does not work together with the -r option.
-m
--modules
Example #1 Printing built in (and loaded) PHP and Zend modules
$ php -m
[PHP Modules]
xml
tokenizer
standard
session
posix
pcre
overload
mysql
mbstring
ctype
[Zend Modules]
-r
--run
Allows execution of PHP included directly on the command line. The PHP start and end tags (<?php and ?>) are not needed and will cause a parse error if present.
Note:
Care must be taken when using this form of PHP not to collide with command line variable substitution done by the shell.
Example #2 Getting a syntax error when using double quotes
$ php -r "$foo = get_defined_constants();"
PHP Parse error:  syntax error, unexpected '=' in Command line code on line 1
Parse error: syntax error, unexpected '=' in Command line code on line 1
The problem here is that sh/bash performs variable substitution even when using double quotes ". Since the variable $foo is unlikely to be defined, it expands to nothing which results in the code passed to PHP for execution actually reading:
$ php -r " = get_defined_constants();"
The correct way would be to use single quotes '. Variables in single-quoted strings are not expanded by sh/bash.
Example #3 Using single quotes to prevent the shell's variable substitution
$ php -r '$foo = get_defined_constants(); var_dump($foo);'
array(370) {
["E_ERROR"]=>
int(1)
["E_WARNING"]=>
int(2)
["E_PARSE"]=>
int(4)
["E_NOTICE"]=>
int(8)
["E_CORE_ERROR"]=>
[...]
If using a shell other than sh/bash, further issues might be experienced - if appropriate, a bug report should be opened at » http://bugs.php.net/. It is still easy to run into trouble when trying to use variables (shell or PHP) in commnad-line code, or using backslashes for escaping, so take great care when doing so. You have been warned!
Note:
-r is available in the CLI SAPI, but not in the CGI SAPI.
Note:
This option is only intended for very basic code, so some configuration directives (such as auto_prepend_file and auto_append_file) are ignored in this mode.
-B
--process-begin
PHP code to execute before processing stdin. Added in PHP 5.
-R
--process-code
PHP code to execute for every input line. Added in PHP 5.
There are two special variables available in this mode: $argn and $argi. $argn will contain the line PHP is processing at that moment, while $argi will contain the line number.
-F
--process-file
PHP file to execute for every input line. Added in PHP 5.
-E
--process-end
PHP code to execute after processing the input. Added in PHP 5.
Example #4 Using the -B , -R and -E options to count the number of lines of a project.
$ find my_proj | php -B '$l=0;' -R '$l += count(@file($argn));' -E 'echo "Total Lines: $l\n";'
Total Lines: 37328
-S
--server
Starts built-in web server. Available as of PHP 5.4.0.
-t
--docroot
Specifies document root for built-in web server. Available as of PHP 5.4.0.
-s
--syntax-highlight and --syntax-highlighting
Display colour syntax highlighted source.
This option uses the internal mechanism to parse the file and writes an HTML highlighted version of it to standard output. Note that all it does is generate a block of <code> [...] </code>HTML tags, no HTML headers.
Note:
This option does not work together with the -r option.
-v
--version
Example #5 Using -v to get the SAPI name and the version of PHP and Zend
$ php -v
PHP 5.3.1 (cli) (built: Dec 11 2009 19:55:07)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2009 Zend Technologies
-w
--strip
Display source with comments and whitespace stripped.
Note:
This option does not work together with the -r option.
-z
--zend-extension
Load Zend extension. If only a filename is given, PHP tries to load this extension from the current default library path on your system (usually /etc/ld.so.conf on Linux systems, for example). Passing a filename with an absolute path will not use the system's library search path. A relative filename including directory information will tell PHP to try loading the extension relative to the current directory.
--ini
Show configuration file names and scanned directories. Available as of PHP 5.2.3.
Example #6 --ini example
$ php --ini
Configuration File (php.ini) Path: /usr/dev/php/5.2/lib
Loaded Configuration File:         /usr/dev/php/5.2/lib/php.ini
Scan for additional .ini files in: (none)
Additional .ini files parsed:      (none)
--rf
--rfunction
Show information about the given function or class method (e.g. number and name of the parameters). Available as of PHP 5.1.2.
This option is only available if PHP was compiled with Reflection support.
Example #7 basic --rf usage
$ php --rf var_dump
Function [ <internal> public function var_dump ] {
- Parameters [2] {
Parameter #0 [ <required> $var ]
Parameter #1 [ <optional> $... ]
}
}
--rc
--rclass
Show information about the given class (list of constants, properties and methods). Available as of PHP 5.1.2.
This option is only available if PHP was compiled with Reflection support.
Example #8 --rc example
$ php --rc Directory
Class [ <internal:standard> class Directory ] {
- Constants [0] {
}
- Static properties [0] {
}
- Static methods [0] {
}
- Properties [0] {
}
- Methods [3] {
Method [ <internal> public method close ] {
}
Method [ <internal> public method rewind ] {
}
Method [ <internal> public method read ] {
}
}
}
--re
--rextension
Show information about the given extension (list of php.ini options, defined functions, constants and classes). Available as of PHP 5.1.2.
This option is only available if PHP was compiled with Reflection support.
Example #9 --re example
$ php --re json
Extension [ <persistent> extension #19 json version 1.2.1 ] {
- Functions {
Function [ <internal> function json_encode ] {
}
Function [ <internal> function json_decode ] {
}
}
}
--rz
--rzendextension
Show the configuration information for the given Zend extension (the same information that is returned by phpinfo()). Available as of PHP 5.4.0.
--ri
--rextinfo
Show the configuration information for the given extension (the same information that is returned by phpinfo()). Available as of PHP 5.2.2. The core configuration information is available using "main" as extension name.
Example #10 --ri example
$ php --ri date
date
date/time support => enabled
"Olson" Timezone Database Version => 2009.20
Timezone Database => internal
Default timezone => Europe/Oslo
Directive => Local Value => Master Value
date.timezone => Europe/Oslo => Europe/Oslo
date.default_latitude => 59.930972 => 59.930972
date.default_longitude => 10.776699 => 10.776699
date.sunset_zenith => 90.583333 => 90.583333
