stripslashes

(PHP 4, PHP 5)

stripslashes — Un-quote string quoted with addslashes()

说明

string stripslashes ( string $str )

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() 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.

参数

str

The input string.

返回值

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

范例

Example#1 A stripslashes() example

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

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

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

Example#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
        )

)
