Parse a string containing a URL then delimited numbers, then populate an array repeating the URL with those numbers

I am having some issues with PHP preg_replace.

I have a url that contains a image-url with numbers added, e.g.:

$url = http://example.com/111.jpg,121,122,123,124,125,126

The numbers at the end are always different.

To separate the string, I am using

$parts = explode(",", $url);

To figure out how many numbers there are, I am using:

$numbers = count($parts);

My problem is to replace the end of $url[0] with $parts (starting with parts[1] up to parts[$numbers-1])

Any idea what I need to change??

Here is my code:

for ($i = 1; $i <= 10; $i++) {
   $array[] = preg_replace('/\d+.jpg/', sprintf("%01d.jpg", $i), $url[0]);
}

<img src="<?php echo($array[0]); ?>"/>
<img src="<?php echo($array[1]); ?>"/>
<img src="<?php echo($array[2]); ?>"/>
<img src="<?php echo($array[3]); ?>"/>
<img src="<?php echo($array[4]); ?>"/>
<img src="<?php echo($array[5]); ?>"/>
<img src="<?php echo($array[6]); ?>"/>
<img src="<?php echo($array[7]); ?>"/>
<img src="<?php echo($array[8]); ?>"/>
<img src="<?php echo($array[9]); ?>"/>
Solution

  • Try

    $array[] = preg_replace('/\d+.jpg/', "{$url[$i]}.jpg"), $url[0]);

    This'll pull out the trailing numbers one at a time. Your original version was replacing with your loop counter, which almost surely were NOT going to be the same as the trailing numbers.

    Yours is generating

    http://example.com/001.jpg
http://example.com/002.jpg
etc...

    and you want

    http://example.com/121.jpg
http://example.com/122.jpg
etc...
