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 (\).
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
)
) |
