你是不是在用foreach 时出现这样的错误呢?Warning: Invalid argument supplied for foreach()

语法:foreach(array as value => value2)

实例:

$Array =array(1,2,3,4);

$Temp = false;

foreach( $Array as $out =>$temp){

}

这样就会输出1234

foreach( $Trray as $out =>$temp){

    echo $temp;

}

会出错:

Warning: Invalid argument supplied for foreach() in E:wwwrootshinywwwrootincludesmodulesshippingems.php on line 92

哈哈,你应该知道为什么会出现上面的错误了吧。
