我有一个动态的数组。我想搜索是否有像＆＃34; Engraving＆＃34;这样的值，那么它应该返回true。 如何在多维数组中实现数组搜索，如下所示

答案 0 :(得分：2)
您可以使用递归函数。
function in_array_recursive($needle, $haystack) {
foreach ($haystack as $value) {
if ($needle == $value) return true;
if (is_array($value) && in_array_recursive($needle, $value)) return true;
}
return false;
}
$found = in_array_recursive('Engraving', $your_array);
以上功能仅匹配整个值。如果您需要匹配部分字符串，则需要添加一个strpos check （Thanks，AbraCadaver）。
function in_array_recursive($needle, $haystack) {
foreach ($haystack as $value) {
if (is_array($value)) {
if (in_array_recursive($needle, $value)) return true;
} else {
if (strpos($value, $needle) !== false) return true;
}
}
return false;
}
$found = in_array_recursive('Engraving', $your_array);
