stripslashes

(PHP 3, PHP 4, PHP 5)

stripslashes -- Un-quote string quoted with addslashes()

Description

string stripslashes ( string str )

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

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

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.

Przykład 1. A stripslashes() example

<?php

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


                
// Outputs: Is your name O'reilly?

                echo stripslashes($str);
?>

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

Przykład 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);
?>

Powyższy przykład wyświetli:

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

)
