Question

During the table echo how would I replace all digits using regex?

I wish to use regex to replace all digits with a span holding the digits so I can change their class.

I can’t add the spans during the echo because the table is pulled from a text file and echo’d on screen, it would have to replace the digits already pulled in from the text file.

PHP:

//set file
$filename='schedule.txt';
//open
$handler=fopen('schedule.txt','r');
//read through file
$file=fread($handler,filesize($filename));
$lines=explode("\r\n",$file);
etc....

You could do something like:

$changed_lines = preg_replace('#(\d+)#', '<span class="bla">$1</span>', $lines);
