Although there are many functions for processing arrays in php, some The function also needs to be encapsulated by ourselves, for example, replacing the elements in the array:

The following is to replace the key of the array with the KEY value:

<?php
 
$arr = array();
$array = array(
    0 => array(shop_name=>1,shop_id=>2),
    1 => array(shop_name => 2, shop_id=>3)
);
 
for($i=0; $i<count($array); $i++) {
    $arr[$i][name] = $array[$i][shop_name];
$arr[$i][id]=$array[$i][shop_id];
}
echo &#39;<pre class="brush:php;toolbar:false">&#39;;
print_r ($arr);
echo &#39;

';   ?>

Replace in the array with { }.

You can use this function according to the actual situation. It is very convenient to replace elements in the array;

<?php
    $arr = array("<小刚>","<小晓>","<小飞>","<小李>","<小红>");
    function arrContentReplact($array)
    {
        if(is_array($array))
        {
            foreach($array as $k => $v)
            {
                $array[$k] = arrContentReplact($array[$k]);
            }
        }else
        {
            $array = str_replace(array(&#39;<&#39;, &#39;>&#39;), array(&#39;{&#39;, &#39;}&#39;), $array);
        }
        return $array;
    }
   
    $arr3 = arrContentReplact($arr);
   
    echo "<pre class="brush:php;toolbar:false">";
    print_r($arr3);
    echo "

"; ?>

The output result of the above example is:

Array
(
    [0] => {小刚}
    [1] => {小晓}
    [2] => {小飞}
    [3] => {小李}
    [4] => {小红}
)
