php - Use file_get_contents() and implode() to pass array to javascript not working -


i developing simple image gallery shows images , related caption. images inside directory , caption in (as single files). php script lists files in both directories , pass arrays javascript wich change image , caption when user press button.

            [...]                 for($x = 2; $x < $lenght; $x++) {                 $filesi[$x] = $imgdirectory."/".$lsi[$x];             }              for($x = 2; $x < $lenght; $x++) {                 $filename = $capdirectory."/".$lsc[$x];                 $filesc[$x] = file_get_contents($filename);             }              //create array js             $captions =  '["' . implode('", "', $filesc). '"]';             $images =  '["' . implode('", "', $filesi). '"]'; ?>     <script>             var captions = <?php echo $captions; ?>;             var images = <?php echo $images; ?>;             [...]

images work , can print caption's file name instead of caption i.e.

$filesc[$x] = $filename;

but when use "file_get_contents()" read file gallery stops working.

if echo $captions , manually set $captions same output e.g.

$captions='["first caption","second caption", "..."]';

the gallery works properly, array should formatted...

thank in advance

solution creating array 2 empty elements (0,1) in order avoid ./ , ../ in file list, have added +2 lsi index.

for($x = 0; $x < $lenght-2; $x++) {                 $filesi[$x] = $imgdirectory."/".$lsi[$x+2];             }

in addition have used json_encode, suggested, instead of manual json encodig. output seems same gallery works!

var images = <?php echo json_encode($filesi); ?>;

in js have escape new lines in strings this:

var multilinestring = "this is\ example";

maybe try use trim() , str_replace() if don't want make easier json_encode().

update

then wrong. did know can push items arrays $array[] = 'item';?
