Php分割字符串转义配额

I need to manage escaping in a comma split. This is a string example:

我需要设法用逗号分隔符进行转义。这是一个字符串示例:

var1,t3st,ax_1,c5\,3,last

I need this split:

我需要这个分裂:

var1
t3st
ax_1
c5\,3
last

Please mind this: "c5\,3" is not splitted.

请注意:“c5\ 3”没有分裂。

I tried with this:

我试着用这个:

$expl=preg_split('#[^\\],#', $text);

But i loose the last char of each split.

但我松开了每个裂口的最后一个字符。

4 个解决方案

#1

use this regex

使用这个正则表达式

$str = 'var1,t3st,ax_1,c5\,3,last';
$expl=preg_split('#(?<!\\\),#', $str);

print_r($expl);  // output Array ( [0] => var1 [1] => t3st [2] => ax_1 [3] => c5\,3 [4] => last )

#2

Try with a lookbehind:

试着向后插入:

preg_split('#(?<!\\),#', $text);

#3

Do a 3 phase approach

采用三相法

First replace \, with someting "unique" like \\

首先，用一些“独特”的像\\。

Do your split by ","

用"，"

Replace \\ with \,

取代\ \ \,

That not as nice as regex but it will work ;)

虽然没有regex那么好，但它会起作用;)

#4

is this ok ?

这是好的吗?

<?php

$text = "var1,t3st,ax_1,c5\,3,last";
$text = str_replace("\,", "#", $text);
$xpode = explode(",", $text);
$new_text = str_replace("#", "\,", $xpode);
print_r($new_text);

?>

Output

输出

Array ( [0] => var1 [1] => t3st [2] => ax_1 [3] => c5\,3 [4] => last )
