I would like to ask, how can i remove -1,-12,-2, -55 dynamically using php?

Answer 1

preg_replace('/-[0-9]+$/', '', $string);

Answer 2

This will work when all of the input is on the same line.

preg_replace('/([a-z\-]+)(-[0-9]+)/', '$1', $data);

With input on multiple lines it would be best to anchor to the end of the string

preg_replace('/^([a-z\-]+)(-[0-9]+)$/', '$1', $data);

Answer 3

You can use preg_replace to replace with a regex. $string in the example below would be the text you are trying to fix. This will replace - and /d+ will replace numeric characters.

$pattern = '/\-/d+$/i';
print preg_replace($pattern, '', $string);
