perl里面，能否提供trim掉字符串两头（全角、半角）空格的函数?

yxzjf

同上，或则有其他的方法？

seacaptain

string trim ( string str [, string charlist])


This function returns a string with whitespace stripped from the beginning and end of str. Without the second parameter, trim() will strip these characters:

apile

沒這個吧??
自己寫吧...
$a =~s/^[\s ]+//g;
$a =~s/[\s ]+$//g;

weiyi_cn

其实还可以这样：
$a =~ s/^\s+|\s+$//g;
就当灌水啦

amorer

搞错了吧，perl哪有这样得语法？
