<?php $int = 12; $min = 1; $max = 100; if(filter_var($int,'FILTER_VALIDATE_INT', array("options"=>array("min_range"=>$min,"max_range"=>$max))) === false){ echo ("The number is valid"); }else{ echo ("The number is not valid"); } ?>

先$arr = range(1,100);
foreach($arr as $k $v)
# {
if($int === cho '在範圍內';
# }else{
# }
這樣行嗎?
