$findme = 'a';
$pos = strpos($mystring, $findme);
php zjistí, zda řetězec obsahuje
if (strpos($string, 'substring') !== false) {
// do stuff
}
Jak mohu zkontrolovat, zda řetězec obsahuje konkrétní slovo?
$a = 'Hello world?';
if (strpos($a, 'Hello') !== false) { //PAY ATTENTION TO !==, not !=
echo 'true';
}
if (stripos($a, 'HELLO') !== false) { //Case insensitive
echo 'true';
}
