foreach在php中出错

Question

我在以下代码中收到错误:

foreach ($result2 as $result2) {


$result2[$i]=  explode(",", $result2[$j]);
}

错误是

Warning: Invalid argument supplied for foreach() in
C:\xampp\htdocs\eplus\vqmod\vqcache\vq2-catalog_controller_product_product.php
on line 417Warning: array_unique() expects parameter 1 to be array, string given in 

我能做什么？

Answer 1

你给这两个变量$result2的foreach()

$i = 0;
foreach ($result2 as $result) {
    $result2[$i]=  explode(",", $result[$j]);
    $i++;
}
