$a = 'aaa,bbb,ccc,"eee,ccc,sss,ppp",dddd,iiii,cccc';

如果碰到这种类型的字符串,我怎么才能使用正则来替换双引号里面的逗号呢?(注:双引号里面有几个逗号不是确定的,上面的只是列子)


回复讨论(解决方案)

在线等,请大侠来指点。

$a = 'aaa,bbb,ccc,"eee,ccc,sss,ppp",dddd,iiii,cccc';echo preg_replace_callback('/".+?"/', function($r) { return str_replace(',', ' ', $r[0]);}, $a);
Copy after login
aaa,bbb,ccc,"eee ccc sss ppp",dddd,iiii,cccc

$a = 'aaa,bbb,ccc,"eee,ccc,sss,ppp",dddd,iiii,cccc';$new=preg_replace('/"(.+?)"/ies',"replace('\\1')",$a);echo $new;//aaa,bbb,ccc,"eeecccsssppp",dddd,iiii,ccccfunction replace($str){	$return=str_replace(',','',$str);	return '"'.$return.'"';}
Copy after login

$a = 'aaa,bbb,ccc,"eee,ccc,sss,ppp",dddd,iiii,cccc';echo preg_replace('/(?<=")(.+?)(?=")/e', 'str_replace(",", " ", "$1")',$a);
Copy after login
