Question

我有一个字符串

$str = 'one,,two,three,,,,,four';

我想像这样排列（print_r的输出）

Array ( [0] => one,two,three,four )

我的代码是

$str = 'one,,two,three,,,,,four';
$str_array = explode(',', $str);
print_r($str_array);

但是没有工作因为多个逗号并排。我怎么能解决这个问题？

Answer 1

您可以使用array_filter函数从数组中删除空元素。

所以你的代码应该是：

$str = 'one,,two,three,,,,,four';
$str_array = array_filter(explode(',', $str));
print_r($str_array);

已编辑的代码

$str = 'one,,two,three,,,,,four';
$str_array = implode(',',array_filter(explode(',', $str)));
echo $str_array; // you will get one,two,three,four

Answer 2

您可以使用preg_replace删除多个逗号作为

$str = 'one,,two,three,,,,,four';
echo $str_new = preg_replace('/,+/', ',', $str);// one,two,three,four
$str_array = explode(' ', $str_new);
print_r($str_array);//Array ( [0] => one,two,three,four )

Answer 3

试试这个

    <?php

    $string = 'one,,two,three,,,,,four';
    $new_array = array_filter(explode(',', $string));

     $final_array[] = implode(',',$new_array);


    print_r($final_array);

    ?>
    OUTPUT:  Array ( [0] => one,two,three,four )

Answer 4

<?php
$string = 'one,,two,three,,,,,four';
$result = array(preg_replace('@,+@', ',', $string));
print_r($result);

输出：

Array ( [0] => one,two,three,four )
