.index
function to find the position of '/'.substr
function with the starting index of 0 and the position of '/' to get the substring before the specified character.$url = 'https://example.com/page';

$index = index($str, ',');
$substring = substr($str, 0, $index);
print "Substring before ',': $substring\n";
