Warning:Invalid argument supplied for foreach() 的中文意思是说foreach需要是一个数组而给它的是一个无效的参数.

php下foreach()错误提示Warning: Invalid argument supplied for foreach()

错误提示:Warning: Invalid argument supplied for foreach() in E:wampwwwmyshopcart.php on line 95

解决方案:就是在循环前面加上判断,直接使用is_array判断给的值是不是为数组,代码如下:

if(is_array($items) && !emptyempty($items)){ 

    foreach( ) 

} 

或者强制转换数据类型,代码如下:

foreach((array)$v as $k1 => $v1) { 

    $edu[$k1][$k] = my_h($v1);// v1是最终要入库的数据,进行转义处理 

}
