Yes. You can use the preg_replace function. It will use regular expressions to remove, change certain characters.

Example:

preg_replace("/\D/", "", "(45) 9 9874-4700");

In regular expressions, \D means: All characters other than 0 to 9.

That is, we select all the characters that are not numbers and in the second parameters we inform by which characters we must change (in this case by none).
