我只想在php中将这种格式的日期dd-mm-yyyy（1991年3月11日）转换为阿拉伯语，而不是像这样（۱。
答案我做了这个逻辑，它完美地工作
$dateofbirth_numerial="03-05-2001";
$numerial_no = array("0","1","2","3","4","5","6","7","8","9","-");
$arabic_no = array("۰","۱","۲","۳","۴","۵","۶","۷","۸","۹","/");
$dateofbirth_arabic = str_replace($numerial_no , $arabic_no , $dateofbirth_numerial);
$result = explode('/',$dateofbirth_arabic);
echo $result[2]."/".$result[1]."/".$result[0]; /* yyyy/mm/dd */
您可以使用PHP本地化方法：
setlocale(LC_TIME, 'ar');
$arabic = strftime('%A %e %B %Y', time());
echo $arabic;
如果你没有看到阿拉伯字母而不是拉丁字母，这可能是因为你的系统上没有安装区域设置。您可以通过运行以下命令来检查已安装的区域设置：locale -a
有关更多选项，请参阅文档：

header('Content-Type: text/html; charset=utf-8');
$standard = array("0","1","2","3","4","5","6","7","8","9");
$eastern_arabic_symbols = array("٠","١","٢","٣","٤","٥","٦","٧","٨","٩");
$current_date = date('d').'-'.date('m').'-'.date('Y');
$arabic_date = str_replace($standard , $eastern_arabic_symbols , $current_date);
您可以尝试str_replace函数
