This is just for a start up not a complete answer. You need to read more about regular expressions and its usage.

remove email addresses :

$pattern = "/[^@\s]*@[^@\s]*\.[^@\s]*/";
$replacement = "[removed]";
preg_replace($pattern, $replacement, $string);

For phone numbers :

$text = preg_replace('/\+?[0-9][0-9()-\s+]{4,20}[0-9]/', '[removed]', $text);

this looks for:

a plus symbol (optional), followed by a number, followed by between 4-20 numbers, brackets, dashes or spaces, followed by a number

and replaces with the string [removed].

Email removal is working fine but phone number removal is not working. I am getting this error: preg_replace(): Compilation failed: invalid range in character class at offset 16 – always-a-learner Dec 06 '17 at 13:17
@ankitsuthar you may need to escape the hyphen by putting a \ in front of it - eg see https://stackoverflow.com/questions/60377374/laravel-preg-replace-compilation-failed-invalid-range-in-character-class – user6122500 Jul 05 '21 at 05:32
