Question

I am new in PHP world. While going through couple of functions i came across stripslash()
I am not clear about it’s benefit. Gone through couple of google link but still it’s benefit is not clear.

<?php
    $array=array("a"=>"0","b"=>"1","c"=>"2");
    print_r ($array);
    print "\n";

    foreach($array as $key=>$value)
    {
            print "Before stripslash : $value\n";
            stripslashes($value);
            print "After stripslash : $value\n";
    }
    print_r ($array);
?>

Output:

Array
(
[a] => 0
[b] => 1
[c] => 2
)

Before stripslash : 0
After stripslash : 0
Before stripslash : 1
After stripslash : 1
Before stripslash : 2
After stripslash : 2

Array
(
[a] => 0
[b] => 1
[c] => 2
)

The PHP docs clearly explain. The first example from that page:

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

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