我想取出“家”字
------解决方案--------------------
引用:会乱码。$str = 'a大家好啊';$regex = '/a大(.*?)好啊/';
header(content-type: text/html; charset=gb2312);
$regex = '/大(.*?)好啊/';
$str = '大家好啊';
$str= mb_convert_encoding($str,'gb2312','utf-8');
$regex = mb_convert_encoding($regex,'gb2312','utf-8');;
$matches = array();
if(preg_match($regex, $str, $matches)){
var_dump($matches);
//array(2) { [0]=> string(12) 大家好啊 [1]=> string(3) 家 }
}
