Question

I am using a foreach loop and a var_dump but the var_dump from the following code outputs something strange. How do I get rid of the pre-prended sring() and quotation marks?

$dir = 'url/dir/dir/';    
$images_array = glob($dir.'*.jpg'); 

$images = array();

foreach ($images_array as $image) {
    $images[] = str_replace($dir, '', $image);   
}


var_dump(implode(',', $images)); 

Output:

string(51) “image1.jpg,image2.jpg,image3.jpg,image4.jpg”

That’s what var_dump does – it prints the datatype and the length. If you want to output just the string use

echo implode(',', $images);
