combine multiple regex into one for comma removing

$reg1 = preg_replace('/(?<!\d),(?=\s+\d)/', '', $text); $reg2 = preg_replace('/,\s*$/', '', $reg1); $reg3 = preg_replace('/\s\s+/', ' ', $reg2);

I have these three regex-replace calls. Can I combine those in one? The first one removes commas after strings and before digits. The second one removes a comma at the end. The third one trims whitespace.

Due to the different replacement values, you can only group your first 2 regex with an "or" condition. preg_replace also allow multiple replacements, so you can pass the 3rd regex as a separate argument.

$result = preg_replace(array('/((?<!\d),(?=\s+\d))|(,\s*$)/', '(\s\s+)'), array('', ' '), $text);

The first two can be combined like:

$reg1 = preg_replace('/(?<!\d),\s*(?=\d|$)/', '', $text);

You could pass all three to preg_replace:

$patterns = array('/(?<!\d),(?=\s+\d)/', '/,\s*$/', '/\s\s+/');
$replacements = array('', '', ' ');

$result = preg_replace($patterns, $replacements, $text);
