求指导一段检测数字的表达式

Jun 23, 2016 pm 02:08 PM

现在想通过打开一个文本文档,内容为:

3月17日,当日营业额88471,同比增加9511,.....



需要将营业额后的88471获取出来赋值给$now,同比截取出来赋值给$bizhi,请问要怎么处理?


回复讨论(解决方案)

$s = '3月17日,当日营业额88471,同比增加9511,.....';preg_match_all('/(\d+),/', $s, $r);list($now, $bizhi) = $r[1];echo $now;//88471echo $bizhi;//9511
Copy after login

调试过程中还出现了一个问题

$file_name="data.txt";$s=file_get_contents($file_name);
Copy after login


data.txt里面就是字符串的内容,怎么输出都是空白呢?

如果你的页面是 utf-8 的,而 data.txt 内容是 gbk 的
那么就  输出都是空白

那么我要怎么才能处理一下这个txt文本呢?自动转换成gbk的?我的页面编码全部都是用gb2312的

你的给出相关代码

编码要一致

打开文件 另存一份 utf-8编码的
