在PHP String中更改IMG src链接

Question

I'm facing trouble whereas the string I pulled from my database is like below

$string = 'The person name Abdul <img src="images/abdul.jpg" alt="abdul"/>.....';

that I need to change it to

$string = 'The person name Abdul <img src="../../images/abdul.jpg" alt="abdul"/>.....';

How do I solve this using PHP?

Answer 1

While not the most elegant solution and with many more out there, you could use PHP's str_replace and do something such as this.

<?php
   $string = 'The person name Abdul <img src="images/abdul.jpg" alt="abdul"/>.....';
   $string = str_replace('src="images/', 'src="../../images/', $string);

   echo $string;
?>

Note: The only reason I added src=" infront of the images part is to help eliminate chances where an image may be misnamed. You could instead use this.

$string = str_replace('images/', '../../images/', $string);

I would recommend not saving items in a database as relative paths. Save just the image names or even better, the full URL of the image and echo it. It's cleaner and a more robust solution for large data (using CDNs, etc).
