title: Echo php array value
body: <p>I have the following code that reads the content of a folder</p>
  
  <p>PHP Code:</p>
  
  <pre><code>&lt;?
  //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
  
  ?&gt;
  </code></pre>
  
  <p>which spits out this the following code:</p>
  
  <pre><code>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";​
  </code></pre>
  
  <p>Now in my html file I want to echo something like </p>
  
  <pre><code>&lt;img src="images/image0.jpg" /&gt;
  &lt;img src="images/image1.jpg"/&gt;
  ...
  ... 
  </code></pre>
  
  <p>How can I do that?</p>
