SYNOPSIS

       string addcslashes (string  $str, string  $charlist)

DESCRIPTION

	Returns a string with backslashes before characters that are listed in $charlist parameter.

PARAMETERS

	      o $str
		- The string to be escaped.

	      <?php
	      echo addcslashes('foo[ ]', 'A..z');
	      // output:  foo[ ]
	      // All upper and lower-case letters will be escaped
	      // ... but so will the []^_`
	      ?>

STRIPSLASHES(3) 							 1							   STRIPSLASHES(3)

stripslashes - Un-quotes a quoted string

SYNOPSIS

       string stripslashes (string  $str)

DESCRIPTION

	Un-quotes a quoted string.

       Note

	       If magic_quotes_sybase is on, no backslashes are stripped off but two apostrophes are replaced by one instead.

	An  example  use of stripslashes(3) is when the PHP directive magic_quotes_gpc is on (it was on by default before PHP 5.4), and you aren't
       inserting this data into a place (such as a database) that requires escaping. For example, if you're simply outputting data  straight  from
       an HTML form.

PARAMETERS

	      o $str
		- The input string.

RETURN VALUES

	Returns a string with backslashes stripped off. ( ' becomes ' and so on.) Double backslashes ( \) are made into a single backslash ( ).

EXAMPLES

       Example #1

	      A stripslashes(3) example

	      <?php
	      $str = "Is your name O'reilly?";

	      // Outputs: Is your name O'reilly?
	      echo stripslashes($str);
	      ?>

       Note

	      stripslashes(3) is not recursive. If you want to apply this function to a multi-dimensional array, you need to use a recursive func-
	      tion.

       Example #2

	      Using stripslashes(3) on an array

	      <?php
	      function stripslashes_deep($value)
	      {
		  $value = is_array($value) ?
			      array_map('stripslashes_deep', $value) :
			      stripslashes($value);

		  return $value;
	      }

	      // Example
	      $array = array("f\'oo", "b\'ar", array("fo\'o", "b\'ar"));
	      $array = stripslashes_deep($array);

	      // Output
	      print_r($array);
	      ?>

	      The above example will output:

	      Array
	      (
		  [0] => f'oo
		  [1] => b'ar
		  [2] => Array
		      (
			  [0] => fo'o
			  [1] => b'ar
		      )

	      )
