本文实例讲述了php下foreach()错误提示Warning: Invalid argument supplied for foreach() 的解决方法。分享给大家供大家参考。具体实现方法如下:

一、问题:

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

二、解决方案:

错误提示 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.

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:

复制代码 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:

复制代码 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 
}

希望本文所述对大家的php程序设计有所帮助。
