求教 多维数组中删除空记录
想让空记录都删除掉,而且删除后,有的key不在了,要把key的顺利也重新排列
比如删除了 $arr['0'] $arr['3'] $arr['5'] ,那么整理后的可以是 $arr['0'] $arr['1'] $arr['2'] $arr['3'] $arr['4']$arr['5'].。。。。
当然图片是二维数组,就是想让删除后,后续的key顺序也跟上来
用过网上的方法都不好使
function array_no_empty($arr) {
if (is_array($arr)) {
foreach ( $arr as $k => $v ) {
if (empty($v)) unset($arr[$k]);
elseif (is_array($v)) {
$arr[$k] = array_no_empty($v);
}
}
}
return $arr;
}
这个是没用对吗? 老是说中间的 array_no_empty 未定义 什么的
有没有另外的方法 ,谢谢了
回复讨论(解决方案)
你的 array_no_empty 函数是可用的
但是有毛病:会返回空的成员数组
$a = array( array('a' => 0, 'b'=> ''), array('a' => 0, 'b'=> ''), array('a' => 1, 'b'=> '2'),);print_r(array_values(array_no_empty($a)));function array_no_empty($arr) { if (is_array($arr)) { foreach ( $arr as $k => $v ) { if (empty($v)) unset($arr[$k]); elseif (is_array($v)) { $arr[$k] = array_no_empty($v); } } } return $arr;}
Array( [0] => Array ( ) [1] => Array ( ) [2] => Array ( [a] => 1 [b] => 2 ))
修改了一下
$a = array( array('a' => 0, 'b'=> ''), array('a' => 0, 'b'=> ''), array('a' => 1, 'b'=> '2'),);print_r(array_no_empty($a));function array_no_empty($arr) { if (is_array($arr)) { foreach ( $arr as $k => $v ) { if (empty($v)) unset($arr[$k]); elseif (is_array($v)) { $t = array_no_empty($v); if($t) $arr[$k] = $t; else unset($arr[$k]); } } } return $arr;}
Array( [2] => Array ( [a] => 1 [b] => 2 ))
重排下标可用 array_values 函数
$a = array( array('a' => 0, 'b'=> ''), array('a' => 0, 'b'=> ''), array('a' => 1, 'b'=> '2'),);print_r(array_values(array_no_empty($a)));function array_no_empty($arr) { if (is_array($arr)) { foreach ( $arr as $k => $v ) { if (empty($v)) unset($arr[$k]); elseif (is_array($v)) { $t = array_no_empty($v); if($t) $arr[$k] = $t; else unset($arr[$k]); } } } return $arr;}
Array( [0] => Array ( [a] => 1 [b] => 2 ))
