Temel dizi soru:
$string = "The quick brown cat";
$check1 = "apple";
$check2 = "ball";
$check3 = "cat";
if ( (stripos($string, $check1) === false) ||
(stripos($string, $check2) === false) ||
(stripos($string, $check3) === false)
) {
echo "Fail";
}
Nasıl bir dizi kullanarak yukarıdaki yoğunlaşmasına yok ($ [] kontrol edin)?
Teşekkürler!
$checks = array('apple', 'ball', 'cat');
foreach($checks as $c){
if(strpos($string, $c) === false){
echo "Fail";
break;
}
