Php 将阿拉伯语写入图像时出错
我先前的相关问题: 我的问题是:Php 将阿拉伯语写入图像时出错,php,arabic,imagettftext,Php,Arabic,Imagettftext,我先前的相关问题: 我的问题是: 如果我想在图像中写入 好的,我修复了它,现在输出:احمد 使用此功能: function arab($word){ $w = explode(' ',$word) ; $f = array(array('ا','أ'),'ب','ت','ث','ج','ح','د','ذ','ر','ز','س','ش','ص','ض','ط','ظ','ع','غ','ف','ق','ك','ل','م','ن','ه','و','ى'
- 如果我想在图像中写入
- 好的,我修复了它,现在输出:
احمد
function arab($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:
احمد
(分开的字母)应为:
如何修复此问题?您必须使用bidi转换器
我用它来写波斯语图像

我使用此选项时没有任何问题:
更新:
我分叉了Persian-Log2Vis并更改了一些代码以使其正常工作。
您的反转阿拉伯字符的方式没有考虑到连接符号的性质。
然而,这是一个有效的技巧来解决PHP/GD不能自动支持RTL语言(如阿拉伯语)的问题
您需要做的是使用完全符合您意图的库
确保您的PHP文件编码为unicode/UTF
e、 g.>打开记事本>另存为>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($im);
?>
产出:
对不起,我不明白这个问题。如果你想让显示为的话,为什么要通过这个函数来传递它呢?因为它看起来像的右边,但字母之间有空格,所以似乎破坏了阿拉伯字符串,$f
和$t
行在打印时是无效的语法,如果你将C&P添加到一个普通的编辑器中,它们会恢复正常。如果有人愿意将其与Laravel集成,请在“classmap”部分下将文件路径添加到composer.json。这比上面的解决方案更适合我。上面使用ar php的解决方案丢弃了一些字符,特别是由Android系统格式化的日期创建的非西方数字。
