stripslashes

Description

string stripslashes ( string str )

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

An example use of stripslashes() is when the PHP directive magic_quotes_gpc is on (it's on by default), 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.

例子 1. A stripslashes() example
<?php $str = "Is your name O\'reilly?"; // Outputs: Is your name O'reilly? echo stripslashes($str); ?>

注: stripslashes() is not recursive. If you want to apply this function to a mutli-dimensional array, you need to use a recursive function.

例子 2. Using stripslashes() 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); ?>
上例将输出：
Array ( [0] => f'oo [1] => b'ar [2] => Array ( [0] => fo'o [1] => b'ar ) )
