下划线之间的正则表达式字符串

问题描述

我需要在下划线之间加上标记，例如:Com_x0020_este_x002C__x0020_texto

I need to get the markings between the underscores, for example:Com_x0020_este_x002C__x0020_texto

Com _x0020 _ este _x002C _ _x0020 _ texto

Com_x0020_este_x002C_ _x0020_texto

谢谢！

推荐答案

您正在寻找的preg_replace文档可在以下位置找到: http://php.net/manual/zh/function.preg-replace.php 以及您正在寻找的逻辑如下:

What you are looking for it preg_replace documentation can be found here: http://php.net/manual/en/function.preg-replace.php and the logic you are looking for it as follows:

 $string = "Com_x0020_este_x002C__x0020_texto";
 print preg_replace('/_(.*?)_/', " _$1_ ", $string);

Javascript版本:

var $string = "Com_x0020_este_x002C__x0020_texto";
alert($string.replace(/_(.*?)_/g," _$1_ "));

结果: Com _x0020_ este _x002C_ _x0020_ texto
