我之前的相关问题:

php处理图像:用阿拉伯语,ttf字体写完整的单词

我的问题是:

  • 如果我想写احمد在图像中,它显示为د م ح ا
  • 好吧,我修复了它,现在输出: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) ;

}

但新的问题是:

ا ح م د

(分隔的字母)它应该在哪里:

احمد

我怎样才能解决这个问题?

反转阿拉伯字符的方式没有考虑连接字形的性质。但是,它是解决PHP/GD 不能自动支持 RTL 语言(如阿拉伯语)的问题的有效技巧。

您需要做的是使用完全符合您预期的 ar-php库。

确保您的PHP 文件编码为un​​icode/UTF
例如 > 打开记事本 > 另存为 > 编码为 UTF-8:

在 PHP 中使用imagettftext的阿拉伯文排版示例用法:

<?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:

你必须使用双向转换器我用它在图像中写波斯语

我用这个没有任何问题: https ://github.com/omid/Persian-Log2Vis

更新:我分叉了 Persian-Log2Vis 并更改了一些代码以正常工作。 https://github.com/tahmasebi/Persian-Log2Vis
