我有以下HTML片段，使用PHP和JavaScript：Javascript json_编码（$myVar）；正在给映射，我想要一个字符串数组,javascript,php,Javascript,Php,我有以下HTML片段，使用PHP和JavaScript： <!DOCTYPE html> <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script> <script> var imageIndex = 0; // index into imageNames array v

var imageHeight = 400; // height of image; changed by user clicking size buttons
var imageNames; // names of images user can view in this album
function pageLoaded() // execute this when the page loads.

// PHP -- generate the array of image file names
<?php
function getImageNames($directory)

$extension = strtolower(end($pieces));
if ($extension !== "jpg") { unset($files[$index]); }
}
$files = array_values($files); // reset array
natcasesort($files); // and sort it.
return $files;
