If possible, I don't want to use string detection method where you use string functions to detect the version in a given string output. If it isn't possible then please disregard what I just typed.
如果可能，我不想使用字符串检测方法，您可以使用字符串函数来检测给定字符串输出中的版本。如果不可能那么请忽略我刚输入的内容。
Is there a function to do it like uname() or do I have to write my own function? If so, please give me a headstart or you can make my life easier by teaching me how to do it. Thanks!
是否有像uname（）那样的函数或者我必须编写自己的函数吗？如果是这样，请给我一个开头，或者通过教我如何做到这一点，你可以让我的生活变得更轻松。谢谢！
Btw, I'm using dreamhost shared server if that might help and yes, it has gcc, php5.3 and pear 1.9.4 installed.
顺便说一句，我正在使用dreamhost共享服务器，如果这可能会有所帮助，是的，它安装了gcc，php5.3和pear 1.9.4。

Sorry to disappoint, but that is what you will need to do. The popen function is your friend. Simply call "pear -V" in read mode with popen and store the information in a buffer that you can easily parse to isolate the version numbers for both pear and PHP. It can be done much cleaner, but the gist of it is:
很抱歉让您失望，但这就是您需要做的事情。 popen功能是你的朋友。只需使用popen在读取模式下调用“pear -V”，然后将信息存储在缓冲区中，您可以轻松解析该缓冲区以隔离pear和PHP的版本号。它可以做得更干净，但它的要点是：
FILE *pfd;
char buffer[1024];
char *bp = buffer;
char tmp[100];
size_t len;
size_t line = 0;
if ((pfd = popen ("pear -V", "r")) == NULL) {
fprintf (stderr, "error: failed to open pipe.");
return 1;
}
while (fgets (tmp, 1023, pfd) != NULL && line < 2)
{
len = strlen (tmp);
strncpy (bp, tmp, len);
bp += len;
line++;
}
pclose (pfd);
printf ("\nbuffer:\n\n%s\n\n", buffer);
Output:
输出：
buffer:
PEAR Version: 1.9.4
PHP Version: 5.3.8
The parsing of the version numbers is left for you.
解析版本号留给你。
