I have what seems like quite a simple query. I have the following code in PHP:
$newThumb = str_replace('style="width:170px;"','',$nolinkThumb);
The problem that I have is that the number '170' can be any number therefore I would like my str_replace to reflect this. I have tried using:
$newThumb = str_replace('style="width:[0-9]px;"','',$nolinkThumb);
But this doesn't work. Any help would be greatly appreciated.
Thank you
You need to use regex, but [0-9] in regex means "the digits 0 to 9 repeated once".
What you're actually searching for is [0-9]+ which means "the digits 0 to 9 repeated one or more times":
$string = preg_replace('/style="width:[0-9]+px;"/', '', $string);
Rather than using str_replace you need to use preg_replace to support regular expressions. More info can be found here: http://php.net/manual/en/function.preg-replace.php
So, for example, you could use:
$newThumb = preg_replace('/style="width:[0-9]+px;"/', '', $nolinkThumb);
Nevertheless, you should probably look at generating your HTML correctly, so that the style is kept separately (for example, in a CSS file) from the content and the business logic.
$newThumb = preg_replace('/style="width:[0-9]{1,}px;/', '', $nolinkThumb);
this regex also work. matching 1-X digits and replace the whole string
hope it helps
