PHP_CHECK_SYNTAX(3)							 1						       PHP_CHECK_SYNTAX(3)

php_check_syntax - Check the PHP syntax of (and execute) the specified file

SYNOPSIS

       bool php_check_syntax (string  $filename, [string  &$error_message])

DESCRIPTION

	Performs a syntax (lint) check on the specified $filename testing for scripting errors.

	This is similar to using php -l from the commandline except that this function will execute (but not output) the checked $filename.

	For example, if a function is defined in $filename, this defined function will be available to the file that executed php_check_syntax(3),
       but output from $filename will be suppressed.

       Note

	       For technical reasons, this function is deprecated and removed from PHP. Instead, use php -l somefile.php from the commandline.

PARAMETERS

	      o $filename
		- The name of the file being checked.

	      o $error_message
		- If the $error_message parameter is used, it will contain the error message generated by  the	syntax	check.	$error_message	is
		passed by reference.

RETURN VALUES

	Returns TRUE if the lint check passed, and FALSE if the link check failed or if $filename cannot be opened.

EXAMPLES

       php -l somefile.php

touch - Sets access and modification time of file

SYNOPSIS

       bool touch (string  $filename, [int  $time = time()], [int  $atime])

DESCRIPTION

	Attempts  to set the access and modification times of the file named in the $filename parameter to the value given in $time. Note that the
       access time is always modified, regardless of the number of parameters.

	If the file does not exist, it will be created.

PARAMETERS

	      o $filename
		- The name of the file being touched.

	      o $time
		- The touch time. If $time is not supplied, the current system time is used.

	      o $atime
		- If present, the access time of the given filename is set to the value of $atime. Otherwise, it is set to the value passed to the
		$time parameter. If neither are present, the current system time is used.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      touch(3) example

	      <?php
	      if (touch($filename)) {
		  echo $filename . ' modification time has been changed to present time';
	      } else {
		  echo 'Sorry, could not change modification time of ' . $filename;
	      }
	      ?>

       Example #2

	      touch(3) using the $time parameter

	      <?php
	      // This is the touch time, we'll set it to one hour in the past.
	      $time = time() - 3600;

	      // Touch the file
	      if (!touch('some_file.txt', $time)) {
		  echo 'Whoops, something went wrong...';
	      } else {
		  echo 'Touched file with success';
	      }
	      ?>

NOTES

       Note

	      Note that time resolution may differ from one file system to another.

       Warning

	       Prior to PHP 5.3.0 it was not possible to change the modification time of a directory with this function under Windows.
