如何用PHP,动态截掉字符串”1|10,2|11,3|12“中的|和,号之间的部分,包括|?


回复讨论(解决方案)

str_replace(",","",str_replace("|","",$val)) 替换即可

$s = "1|10,2|11,3|12";echo preg_replace('/\|[^,]+,/', ',', $s);
Copy after login
1,2,3|12

结果是110211,我要的结果是1|10,2|11,3|12 变成1,2,3 拜托!

如何再去掉|12变成1,2,3呢?

$content = '1|10,2|11,3|12';echo preg_replace(array('/\|[^,]+,/','/\|[^,]+$/'), array(',',''), $content);
Copy after login

1,2,3

$s = "1|10,2|11,3|12";echo preg_replace('/\|[^,]+/', '', $s);
Copy after login
1,2,3

但这并不符合: 截掉 | 和 , 号之间的部分

谢谢,结贴!
