What alternative function could be used instead of strrchr to achieve the desired result?

The issue with using strrchr is that it only returns the last occurrence of a character in a string, whereas we want to find the first occurrence. To achieve the desired result, we can use the strpos function to find the position of the first occurrence of a character in a string. We can then use substr to extract the substring from the beginning of the original string up to the position of the character. 

$string = "Hello, World!";
$char = ',';
$position = strpos($string, $char);

if ($position !== false) {
    $substring = substr($string, 0, $position);
    echo $substring;
} else {
    echo "Character not found in string.";
}
