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
}
