preg_split在PHP中有两个分隔符

How to merge two delimiters in preg_split? For example:

如何在preg_split中合并两个分隔符?例如:

$str = "this is a test , and more";
$array = preg_split('/( |,)/', $str, -1, PREG_SPLIT_DELIM_CAPTURE);
print_r($array);

will produce an array as

将生成一个数组作为

Array
(
    [0] => this
    [1] =>  
    [2] => is
    [3] =>  
    [4] => a
    [5] =>  
    [6] => test
    [7] =>  
    [8] => 
    [9] => ,
    [10] => 
    [11] =>  
    [12] => and
    [13] =>  
    [14] => more
)

but I want to get

但我想得到

Array
(
    [0] => this
    [1] =>  
    [2] => is
    [3] =>  
    [4] => a
    [5] =>  
    [6] => test
    [7] => ,
    [8] => and
    [9] =>  
    [10] => more
)

In fact, I want to merge the array elements when two delimiters are neighbors. In other words, ignoring the first delimiter if the next part is the second delimiter.

实际上,当两个分隔符是邻居时,我想合并数组元素。换句话说,如果下一部分是第二个分隔符,则忽略第一个分隔符。

3 个解决方案

#1

Try using a character class: /[ ,]+/

尝试使用字符类:/ [,] + /

The + is a quantifier meaning "1 or more"

+是量词意思是“1或更多”

What about making sure that the situation doesn't happen in the first place :

如何确保首先不会发生这种情况:

<?php
    $str = "this is a test , and more";
    $str=preg_replace('/ *, */',',',$str);
    $array = preg_split('/( |,)/', $str, -1, PREG_SPLIT_DELIM_CAPTURE);
    print_r($array);
?>

Array
(
    [0] => this
    [1] =>  
    [2] => is
    [3] =>  
    [4] => a
    [5] =>  
    [6] => test
    [7] => ,
    [8] => and
    [9] =>  
    [10] => more
)

Using /([, ]+)/ it works. See codepad

使用/([,] +)/它有效。请参阅键盘
