在一个数组中检查多个序列,可以使用PHP中的in_array()函数来实现。该函数用于检查一个值是否存在于数组中。
具体步骤如下:
$found = false;
foreach ($sequences as $sequence) {
if (in_array($targetSequence, $sequence)) {
$found = true;
break;
}
}
完整的代码示例如下:
$sequences = array(array(1, 2, 3), array(4, 5, 6), array(7, 8, 9));
$targetSequence = array(4, 5, 6);
$found = false;
foreach ($sequences as $sequence) {
if (in_array($targetSequence, $sequence)) {
$found = true;
break;
}
}
if ($found) {
echo "待检查的序列存在于数组中";
} else {
echo "待检查的序列不存在于数组中";
}
