具有不同偏移量的 PHP foreach 循环

Question

一种方法是使用 js，使用以下方法计算元素getElementsByClassName：var numberOfElements = document.getElementsByClassName('products').length;然后 ：if (numberOfElements > 9) {document.getElementById('last-img').style.display = 'block';} else {document.getElementById('last-img').style.display = 'none';}

Answer 1

foreach ($json as $key => $row) {

   var_dump($row); //[ 'appid':10, ... ]

   var_dump($row['name']); //counter-strike, ...

   var_dump($key); //10, 20, 30, ...

}

Answer 2

试试这个

foreach ($json as $key => $value){

    //$key = 220

    //$value = the same as $json[$key]

    $value['name'];

    //THE SAME AS

    $json[$key]['name'];

}
