我有以下代码读取文件夹的内容
PHP代码:
<?
//PHP SCRIPT: getimages.php
header('content-type: application/x-javascript');
//This function gets the file names of all images in the current directory
//and ouputs them as a JavaScript array
function returnimages($dirname="./images") {
$pattern="(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$)"; //valid image extensions
$files = array();
$curimage=0;
if($handle = opendir($dirname)) {
while(false !== ($file = readdir($handle))){
if(eregi($pattern, $file)){ //if this file is a valid image
//Output it as a JavaScript array element
echo 'galleryarray['.$curimage.']="'.$file .'";' . "\n";
$curimage++;
}
}
closedir($handle);
}
sort($files);
return($files);
}
echo 'var galleryarray=new Array();' . "\n"; //Define array in JavaScript
returnimages() //Output the array elements containing the image file names
?>
它吐出以下代码:
var galleryarray = new Array();
galleryarray[0] = "image1.jpg";
galleryarray[1] = "image5.jpg";
galleryarray[2] = "image2.jpg";
galleryarray[3] = "image4.jpg";
galleryarray[4] = "image8.jpg";
galleryarray[5] = "image7.jpg";
galleryarray[6] = "image0.jpg";
galleryarray[7] = "image3.jpg";
galleryarray[8] = "image6.jpg";
现在在我的 html 文件中,我想回显类似的内容
<img src="images/image0.jpg" />
<img src="images/image1.jpg"/>
...

我怎样才能做到这一点?
