把上面变成 周一~周五8:00-23:00; 周六10:00-23:00; 周日10:00-22:00;

$str="Mon-Fri 8:00-23:00; Sat 10:00-23:00; Sun 10:00-22:00;"
$en=array("Mon", "Fri","Sat","Sun");
$cn=array("周一", "周五","周六","周日");
$str=str_replace($en, $cn, $str);

请问如何把英文之间的"-"变成~, 时间中间的不替换?
英文和数字间的空格如何替换?


回复讨论(解决方案)

$en=array("Mon-Fri","Sat","Sun");
$cn=array("周一~周五","周六","周日");
$str=str_replace($en, $cn, $str);

可以在你的代码的基础上加增加
$str = preg_replace('/-/','~',$str,1);

$str="Mon-Fri 8:00-23:00; Sat 10:00-23:00; Sun 10:00-22:00"; $en=array("Mon", "Fri","Sat","Sun"); $cn=array("周一", "周五","周六","周日"); $str=str_replace($en, $cn, $str); //echo $str; $a[0]='/([^\d]+)\-/'; $a[1]='/\s(\d)/'; $b[0]='\1~'; $b[1]='\1'; $str=preg_replace($a,$b, $str); echo $str;
Copy after login

就是楼上这样!
