the preview enter image description here

if input 16:00 result success, if input 19:00 still success.

can me fix issue?

thanks in advance

a >= 1 || <= 2 true numeric a. use &&

like this: 

$in1 = $waktu >= $jam1_a && $waktu <= $jam1_b;   $in2 = $waktu >= $jam2_a && $waktu <= $jam2_b; $in3 = $waktu >= $jam3_a && $waktu <= $jam3_b; $result = ($in1 || $in2 || $in3) ? 'success' : 'error'; echo $result;
