PHP数组怎么获取最大值

preg_match_all("/src=\"\/?(.*?)\"/", $_content, $pos);
print_r($pos);
打印结果是：
Array
(
[0] => Array
(
[0] => src="/lib/kindeditor/php/../attached/image/20140811/20140811001239_52942.jpg"
[1] => src="/lib/kindeditor/php/../attached/image/20140811/20140811001239_96704.jpg"
[2] => src="/lib/kindeditor/php/../attached/image/20140811/20140811001239_22153.jpg"
[3] => src="/lib/kindeditor/php/../attached/image/20140811/20140811001239_62245.jpg"
[4] => src="/lib/kindeditor/php/../attached/image/20140811/20140811001240_26476.jpg"
)
[1] => Array
(
[0] => lib/kindeditor/php/../attached/image/20140811/20140811001239_52942.jpg
[1] => lib/kindeditor/php/../attached/image/20140811/20140811001239_96704.jpg
[2] => lib/kindeditor/php/../attached/image/20140811/20140811001239_22153.jpg
[3] => lib/kindeditor/php/../attached/image/20140811/20140811001239_62245.jpg
[4] => lib/kindeditor/php/../attached/image/20140811/20140811001240_26476.jpg
)
)
我想获取
[0] => lib/kindeditor/php/../attached/image/20140811/20140811001239_52942.jpg
[1] => lib/kindeditor/php/../attached/image/20140811/20140811001239_96704.jpg
[2] => lib/kindeditor/php/../attached/image/20140811/20140811001239_22153.jpg
[3] => lib/kindeditor/php/../attached/image/20140811/20140811001239_62245.jpg
[4] => lib/kindeditor/php/../attached/image/20140811/20140811001240_26476.jpg
这一段的最大值应该怎么做

Answer 1

用asort() 排列 显示数据从小到大 然后 end() 获取 最后位值

追问

preg_match_all("/src=\"\/?(.*?)\"/", $_content, $pos);
$my_array=end($pos);
$result=array_search(max($my_array),$my_array);
echo $result;
我这样取出了最大值~没用到asort()
