addcslashes - Quote string with slashes in a C style

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.

	      o $charlist
		-  A  list  of	characters  to be escaped. If $charlist contains characters 
, 
 etc., they are converted in C-like style, while
		other non-alphanumeric characters with ASCII codes lower than 32 and higher than 126 converted to octal representation.  When  you
		define	a sequence of characters in the charlist argument make sure that you know what characters come between the characters that
		you set as the start and end of the range.

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

	      <?php
	      echo addcslashes("zoo['.']", 'z..A');
	      // output:  zoo['.']
