 这篇文章主要介绍了PHP全角半角转换函数,把目前能找到的所有全角都列出来了一个个替换吧,需要的朋友可以参考下

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   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);  }
