PHP：高效检测字符串是否同时包含来自多个数组的任意值

<?php
$array1 = ['night', 'morning', 'afternoon'];
$array2 = ['robert', 'david', 'justin'];
$string = 'robert read a book this morning';

$foundInArray1 = false;
foreach ($array1 as $value) {
    // str_contains() 是 PHP 8+ 的函数，用于判断字符串是否包含子串
    // 对于 PHP 7.x 及更早版本，可以使用 (strpos($string, $value) !== false)
    if (str_contains($string, $value)) {
        $foundInArray1 = true;
        break; // 找到一个匹配项即可，无需继续遍历
    }
}

$foundInArray2 = false;
foreach ($array2 as $value) {
    if (str_contains($string, $value)) {
        $foundInArray2 = true;
        break; // 找到一个匹配项即可，无需继续遍历
    }
}

if ($foundInArray1 && $foundInArray2) {
    echo "Match found: 字符串同时包含来自两个数组的元素。\n";
} else {
    echo "Not found: 字符串不满足同时包含来自两个数组的条件。\n";
}

// 另一个测试案例
$string2 = 'david went to bed at night';
$foundInArray1_2 = false;
foreach ($array1 as $value) {
    if (str_contains($string2, $value)) {
        $foundInArray1_2 = true;
        break;
    }
}
$foundInArray2_2 = false;
foreach ($array2 as $value) {
    if (str_contains($string2, $value)) {
        $foundInArray2_2 = true;
        break;
    }
}
if ($foundInArray1_2 && $foundInArray2_2) {
    echo "Match found for string2: 字符串同时包含来自两个数组的元素。\n";
} else {
    echo "Not found for string2: 字符串不满足同时包含来自两个数组的条件。\n"; // 输出此项
}
?>
