在多维数组上使用preg_match来返回键值数组 [英] Using preg_match on a multidimensional array to return key values arrays

问题描述

  $ data = array（
abc= >数组（
label=>abc，
value=>def，
type=>ghi，
 
，
def=>数组（
label=>mno，
value= >qrs，
type=>tuv，
desc=>wxyz，
），
） 
  

我想用preg_match和foreach循环来执行$ data中包含的数组的搜索，返回键值对的嵌套数组。

解决方案

类似这样的事情？

 <？php 
 $ data = array（
abc=> array（
label=>abc 
value=>def，
type=>ghi，
desc=>jkl，
），
def=>数组（
label=>mno，
value=>qrs，
type=> tuv，
desc=>wxyz，
），
）; 
 
 $ matches = array（）; 
 $ pattern =/ a / i; //包含通过数据
 foreach（$ data as $ key => $ value）的$ a 
循环{
 //遍历数据子数组下的每个键
 foreach（$ value为$ key2 => $ value2）{
 //检查是否匹配。 
 if（preg_match（$ pattern，$ value2））{
 // add to matches array。 
 $匹配[$ key] = $ value; 
 //匹配找到，所以从foreach中断到
 break; 
 
 
 $ b echo'< pre>。print_r（$ matches，true）。'< / pre>'; 
？> 
  

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",
            ),
    );

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.

解决方案

Something like this?

<?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>';
?>
