不需要的\字符

Question

php code:

<?php 
echo json_encode(glob("photos-".$_GET["folder"].'/*.jpg'));
?>

it return :

["photos-animaux\/ani-01.jpg","photos-animaux\/ani-02.jpg","photos-animaux\/ani-02b.jpg","photos-animaux\/ani-03.jpg","photos-animaux\/ani-04.jpg","photos-animaux\/ani-05.jpg","photos-animaux\/ani-06.jpg","photos-animaux\/ani-07.jpg","photos-animaux\/ani-08.jpg","photos-animaux\/ani-09.jpg","photos-animaux\/ani-10.jpg","photos-animaux\/ani-11.jpg","photos-animaux\/ani-12.jpg","photos-animaux\/ani-13.jpg","photos-animaux\/ani-14.jpg"]

Which is ALMOST perfect, except for the \ character... Where did it come from?

Here is the jquery code that calls it:

$.get(  'photolister.php',
                    {'folder' : $(this).attr('href')},
                    function(data){startSlideshow(data);console.log(data);}
                );

Answer 1

PHP is automatically escaping the string.

You can use stripslashes to remove the unwanted slashes.

You could also use the GLOB_NOESCAPE flag in your glob() call.
