Delete row from php array
提问by ensnare
How can I remove an element from an array?
如何从数组中删除元素?
For example:
例如:
$data = Array('first' , 'second' , 'third');
array_delete($data[2]);
#$data would now read Array('first', 'second')
Does such a built-in function exist? Thanks.
这样的内置函数存在吗?谢谢。

yes. i would have made it shorter, but need at least 30- charcters. so here you go:
是的。我会缩短它,但至少需要 30 个字符。所以你走吧:
unset($data[2]);

The above answers work. But here is what i got from the site listed below. I think its cool.
以上答案有效。但这是我从下面列出的网站上得到的。我觉得很酷。
//deletes a number on index $idx in array and returns the new array
function array_delete($idx,$array) {
unset($array[$idx]);
return (is_array($array)) ? array_values($array) : null;
}
