替换描述中的图像的src

Question

I have a string coming from database as given below. I want to change the img src in the text below to be ./upload-files/<filename> instead of ../upload-files/<filename>.

<p><span style="text-decoration: line-through;">
<img style="float: left; margin-left: 5px; margin-right: 5px;" src="../upload-files/teddybear.jpg">
</span></p>

So basically I want image to use the current directory instead of the parent directory ../ How can i do this? Is preg_replace the right tool here?

Answer 1

If you are using an intermediary variable to store your image you can use:

$img_url = '../upload-files/teddybear.jpg';

$img_url = print_r(preg_replace('/^\.\./', '.', $img_url));

<p><span style="text-decoration: line-through;">
<img style="float: left; margin-left: 5px; margin-right: 5px;" src="<?php echo $img_url;?>">
</span></p>

if you are trying to replace ../ inside a bunch of html, use this:

$my_html = '<p><span style="text-decoration: line-through;">
<img style="float: left; margin-left: 5px; margin-right: 5px;" src="../upload-files/teddybear.jpg">
</span></p>';

print_r(preg_replace('/"\.\./', '".', $my_html));
