There are variables in PHP variable names

$a = array(    array(        'name' => 'lang',        'user' => '0',        'value' => 'zh-CN'        ),    array(        'name' => 'charset',        'user' => '22',        'value' => 'UTF-8'        ),);

To output ZH-CN on the page with $site [' Lang '], $site [' charset '] output UTF-8

My mistakes, the wording

foreach ($a as $opt) {    foreach ($opt as $key => $value) {        if ($key == 'name') {            $key_name = $value;        }        if ($key == 'value') {            $key_value = $value;        }    }    $site = 'site[\''. $key_name .'\']';    $$site = $key_value;}

//if your php version >= 5.5$site = array_column($a, 'name', 'value');//else$site = array();foreach($a as $t) $site[$t['name']] = $t['value'];
