我有一个结构如下的数组:
I have an array that is structured as such:
$data = array(
"abc"=>array(
"label" => "abc",
"value" => "def",
"type" => "ghi",
"desc" => "jkl",
),
"def"=>array(
"label" => "mno",
"value" => "qrs",
"type" => "tuv",
"desc" => "wxyz",
),
);
我想使用带有 foreach 循环的 preg_match 对 $data 中包含的数组执行搜索并返回键值对的嵌套数组.
I want to use preg_match with a foreach loop to perform a search on the arrays contained in $data and return the nested arrays of key value pairs.
类似的事情?
<?php
$data = array(
"abc"=>array(
"label" => "abc",
"value" => "def",
"type" => "ghi",
"desc" => "jkl",
),
"def"=>array(
"label" => "mno",
"value" => "qrs",
"type" => "tuv",
"desc" => "wxyz",
),
);
$matches = array();
$pattern = "/a/i"; //contains an 'a'
//loop through the data
foreach($data as $key=>$value){
//loop through each key under data sub array
foreach($value as $key2=>$value2){
//check for match.
if(preg_match($pattern, $value2)){
//add to matches array.
$matches[$key]=$value;
//match found, so break from foreach
break;
}
}
}
echo '<pre>'.print_r($matches, true).'</pre>';
?>
