求正则匹配tab， \t貌似也会匹配空格呢


回复讨论(解决方案)

这么可能呢？分析如下 

$s = ' 	'; //一个空格加一个制表符echo current(unpack('H*', $s)); //2009 20是空格的十六进制内码，09是Tab键的十六进制内码preg_match("/\t+/", $s, $r);echo current(unpack('H*', $r[0])); //得到 09preg_match("/ +/", $s, $r);echo current(unpack('H*', $r[0])); //得到 20preg_match("/\s+/", $s, $r);echo current(unpack('H*', $r[0])); //得到 2009

我的编辑器错了，都是tab键，一个tab显示的距离只有空格的宽度，晕死
