How to check whether a string starts with another string in PHP

Answer 1

function string_start_with($s, $match) {
    $s_len = strlen($s);
    $m_len = strlen($match);
    if ($m_len > $s_len) {
        return false;
    }
    
    return substr($s, 0, $m_len) === $match;
}

$s = "php python c c++ java";

if (string_start_with($s, "php")) {
    echo "yes";
} else {
    echo "no";
}

    
   
           
    
/*
run:
                
yes
         
*/
