Question

我之前的相关问题：

php work with images : write complete word in arabic , ttf font

我的问题是：

如果我想在图片中写下احمد，则会显示为د م ح ا
好吧，我修复了它，现在是输出：ا ح م د

使用此功能：

function arab($word){

       $w = explode(' ',$word) ;

       $f = array(array('ا','أ'),'ب','ت','ث','ج','ح','د','ذ','ر','ز','س','ش','ص','ض','ط','ظ','ع','غ','ف','ق','ك','ل','م','ن','ه','و','ى');

       $t = array(array('ا_','أ_'),'ب_','ت_','ث_','ج_','ح_','د_','ذ_','ر_','ز_','س_','ش_','ص_','ض_','ط_','ظ_','ع_','غ_','ف_','ق_','ك_','ل_','م_','ن_','ه_','و_','ى_');

       $my_arab = '' ;

       foreach($w as $wo)
        {
             $r  = array() ;

             $wo = str_replace($f , $t ,$wo);

             $ne = explode('_', $wo) ;

             foreach($ne as $new) {
                $new = str_replace('_','',$new) ;
                array_unshift($r , $new);
             }

            $my_arab .=  ' '.implode('',$r) ;

        }

     return trim($my_arab) ;

}

但新问题是：

ا ح م د

（分开的字母）应该是：

احمد

我该如何解决这个问题？

Answer 1

逆转阿拉伯字符的方式不会考虑连接字形的性质。但是，解决 PHP / GD不能自动支持RTL语言的问题是一个有效的技巧。

您需要做的是使用完全符合您预期的ar-php库。

确保 PHP文件编码 unicode / UTF 。
例如＆GT;打开记事本＆gt;另存为＆gt;编码为UTF-8：

使用 imagettftext ：
在PHP中使用阿拉伯语排版的示例用法
<?php // The text to draw require('./I18N/Arabic.php'); $Arabic = new I18N_Arabic('Glyphs'); $font = './DroidNaskh-Bold.ttf'; $text = $Arabic->utf8Glyphs('لغةٌ عربيّة'); // Create the image $im = imagecreatetruecolor(600, 300); // Create some colors $white = imagecolorallocate($im, 255, 255, 255); $grey = imagecolorallocate($im, 128, 128, 128); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, 599, 299, $white); // Add the text imagettftext($im, 50, 0, 90, 90, $black, $font, $text); // Using imagepng() results in clearer text compared with imagejpeg() imagepng($im, "./output_arabic_image.png"); echo 'open: ./output_arabic_image.png'; imagedestroy($im); ?>

输出：

您必须使用bidi转换器我用它来写图像中的波斯语
