PHP字符串解析 [英] PHP string parsing

问题描述

我正在尝试使用其唯一标识符来解析操作系统实例的列表.我正在寻找一种解析文本字符串并将值传递给两个变量的解决方案.要解析的字符串如下:

I am trying to parse a list of operating system instances with their unique identifiers. I am looking for a solution to parse a text string, and pass the values into two variables. The string to be parsed is as followed:

"Ubuntu 9.10" {40f2324d-a6b2-44e4-90c3-0c5fa82c987d}

推荐答案

我一直在寻找借口阅读

I've been looking for an excuse to read the docs for sscanf():

sscanf($s, '"%[^"]" {%[^}]}', $os, $ident);
echo $os, "<br>", $ident;

后续行动:为了方便起见，在当前针对此问题的三个答案中:

Followup: For interest's sake, out of the three answers currently on this question:

sscanf: 0.92999792098999 seconds
preg_match: 4.73761510849 seconds
str_replace x2 + preg_split: 3.7644839286804 seconds

在此处进行基准测试.有趣的是，两个str_replace()和一个preg_split()比preg_match()快.

Benchmark here. Funny that two str_replace() and a preg_split() are faster than the preg_match().
