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