回复讨论(解决方案)
为什么要这样写呢?
$val = each( &$var )[1];
$key = each( &$var )[0];
这样不行吗?
$val = each( $var )[1];
$key = each( $var )[0];
写作这样不是更好?
list($key, $val) = each( $var );
为什么要这样写呢?
$val = each( &$var )[1];
$key = each( &$var )[0];
这样不行吗?
$val = each( $var )[1];
$key = each( $var )[0];
写作这样不是更好?
list($key, $val) = each( $var ); 一这样环境就卡死了
没道理的!
你不能因为你的程序有问题就乱改一气
each( &$var ) 出错的原因是不能这样传递引用,这是 php 5.3 才有的约定
而 each( $var )[0] 这样的写法是 php 5.3 才有的
如果同时遵守 php 5.3 的语法规则就卡死,那你就要想想你的问题出在哪里了

do while(1) 无限循环没有退出的语句,为何会不卡?
那你 print_r($_POST['var']); 贴出结果
do while(1) 无限循环没有退出的语句,为何会不卡? 大侠求助,刚入门 如何退出
if ( each( &$var ) )
{
$msql->query( "update {P}_base_config set value='{$val}' where variable='{$key}'" );
break;
}
这样就能退出了
