PHP:删除多维数组中的空数组字符串 [英] PHP: remove empty array strings in multidimensional array

问题描述

我有这个数组:

$aryMain = array(array('hello','bye'), array('',''),array('','')); 

它是通过读取一个csv文件形成的，数组('','')是文件末尾的空行.

It is formed by reading a csv file and the array('','') are the empty rows at the end of the file.

我怎样才能删除它们?

我试过了:

$aryMain = array_filter($aryMain);  

但它不起作用:(

非常感谢！

推荐答案

添加到 Rikesh 的答案:

To add to Rikesh's answer:

<?php
$aryMain = array(array('hello','bye'), array('',''),array('','')); 
$aryMain = array_filter(array_map('array_filter', $aryMain));
print_r($aryMain);

?>

将他的代码粘贴到另一个 array_filter 中将摆脱整个数组本身.

Sticking his code into another array_filter will get rid of the entire arrays themselves.

Array
(
    [0] => Array
        (
            [0] => hello
            [1] => bye
        )

)

对比:

$aryMain = array_map('array_filter', $aryMain);

Array
(
    [0] => Array
        (
            [0] => hello
            [1] => bye
        )

    [1] => Array
        (
        )

    [2] => Array
        (
        )

)
