之前试过网上找的通过ASCII之类的字符替换,发现很多莫名其妙的问题。最后还是换成下面的字符替换方式了,把目前能找到的所有全角都列出来了一个个替换吧
复制代码 代码如下:
/**
* 全角字符转换为半角
*
* @param string $str
* @return string
*/
public function Sbc2Dbc($str)
{
$arr = array(
'0'=>'0', '1'=>'1', '2'=>'2', '3'=>'3', '4'=>'4','5'=>'5', '6'=>'6', '7'=>'7', '8'=>'8', '9'=>'9',
'A'=>'A', 'B'=>'B', 'C'=>'C', 'D'=>'D', 'E'=>'E','F'=>'F', 'G'=>'G', 'H'=>'H', 'I'=>'I', 'J'=>'J',
'K'=>'K', 'L'=>'L', 'M'=>'M', 'N'=>'N', 'O'=>'O','P'=>'P', 'Q'=>'Q', 'R'=>'R', 'S'=>'S', 'T'=>'T',
'U'=>'U', 'V'=>'V', 'W'=>'W', 'X'=>'X', 'Y'=>'Y','Z'=>'Z', 'a'=>'a', 'b'=>'b', 'c'=>'c', 'd'=>'d',
'e'=>'e', 'f'=>'f', 'g'=>'g', 'h'=>'h', 'i'=>'i','j'=>'j', 'k'=>'k', 'l'=>'l', 'm'=>'m', 'n'=>'n',
'o'=>'o', 'p'=>'p', 'q'=>'q', 'r'=>'r', 's'=>'s', 't'=>'t', 'u'=>'u', 'v'=>'v', 'w'=>'w', 'x'=>'x',
'y'=>'y', 'z'=>'z',
'('=>'(', ')'=>')', '〔'=>'(', '〕'=>')', '【'=>'[','】'=>']', '〖'=>'[', '〗'=>']', '“'=>'"', '”'=>'"',
'‘'=>'\'', '''=>'\'', '{'=>'{', '}'=>'}', '《'=>''>','%'=>'%', '+'=>'+', '—'=>'-', '-'=>'-',
'~'=>'~',':'=>':', '。'=>'.', '、'=>',', ','=>',', '、'=>',', ';'=>';', '?'=>'?', '!'=>'!', '…'=>'-',
'‖'=>'|', '”'=>'"', '''=>'`', '‘'=>'`', '|'=>'|', '〃'=>'"',' '=>' ', '×'=>'*', ' ̄'=>'~', '.'=>'.', '*'=>'*',
'&'=>'&','<'=>''>', '$'=>'$', '@'=>'@', '^'=>'^', '_'=>'_', '"'=>'"', '¥'=>'$', '='=>'=',
'\'=>'\\', '/'=>'/'
);
return strtr($str, $arr);
}
