When using the preg_replace() function you can capture elements of the input string into strings $1, $2 and so on, so that they can be used in the output.
What I want to do is store the contents of $1 into a variable so that I can use it outside of the preg_replace function.
Is this possible?
Here’s what I’m working on:
$text = preg_replace('/\\[DOWNLOAD=([-a-z0-9._~:\\/?#@!$&\\'( )*+,;=%]+)](.+?)\\[\\/DOWNLOAD]/i', '<a href="download.php"><img src="/images/download.png" /></a>', $text); $file = $1 return[$text, $file]
What I want the end user to do is be able to type a short code, which will create a download link to the file indicated in the short code.
So, for example, [DOWNLOAD=“example.pdf”], would create the link, then store the filename into a string, then pass that to another script which could then select the file from the server.
I hope that makes sense.
Thanks in advance for your help.
