regex to detect whole string in php

can anyone php expert help me to detect this [$string=\n\n(\n\n52556\n\n)] in php via Regex

because i want to remvoe form this line

now : Domino Developer \n\n(\n\n52338\n\n) Reston
my requirement : Domino Developer Reston


$string=\n\n(\n\n52556\n\n)

 

This is just a quick way, that I would use

<?php

$now = "Domino Developer \n\n(\n\n52338\n\n) Reston";

// lets remove what you dont't want \n\n(\n\n52338\n\n) leaving letters and spaces only
$now = preg_replace("#[^A-Za-z ]#", "", $now); 

// opps we ended up with 2 spaces before "Reston", lets change that to 1 space
$my_requirements = str_replace('  ',' ',$now);

// All Done, this is what you wanted
echo $my_requirements; // Domino Developer Reston

?>

PHP:
