Code gems · February 4, 2013

After retrieving one character from the string held in the array, he tests whether the result could be equal to a word.

$user_regime = trim(strtoupper(remove_everything_but_letter_space(substr($tabinfouser[17], 0, 1))));
if ($user_regime == 'ALPHA') $user_regime = 'A';
else if ($user_regime == 'BETA') $user_regime = 'B';
else if ($user_regime == 'OMEGA') $user_regime = 'O';
else if ($user_regime == 'EPSILON') $user_regime = 'E';

Code of the function remove_everything_but_letter_space:

function remove_everything_but_letter_space($string)
{
	$string = preg_replace('/[^A-Za-z \-]/', '', $string);
	return $string;
}
