Php form validation not working for me

Question

I have tried with below code. the code only validating "yourname". yourlname and umobile not validating. Please let me know the mistake which I have done in the code.

if(strlen($yourname)<4) 
{
    $output = json_encode(array('type'=>'error', 'text' => 'Name is too short!'));
    die($output);
}
if(strlen($yourlname)) 
{
    $output = json_encode(array('type'=>'error', 'text' => 'Please enter Last Name'));
    die($output);
}

if(strlen($umobile)) 
{
    $output = json_encode(array('type'=>'error', 'text' => 'Please enter Mobile Number'));
    die($output);
}

strlen Returns the length of a string on success, and 0 if the string is empty and you always enter in if condition. Instead use !empty($yourlname){} — Saty

Because the condition its validating fine is the only correct one you have — Hanky Panky

Use like this

  if(!strlen(trim($yourlname)))

And

 if(!strlen(trim($umobile)))
