我在 PHP/GD 中将文本写入图像模板得到了很好的结果，文本换行很好但不是“平滑”，这是我正在使用的代码：

<?php

header("Content-type: image/png");

$text = "go to school go to school go to school go to school go to school go to school go to school go to school go to school go to school go to school ";
$arrText=explode("\n",wordwrap($text,60,"\n"));

$im = imagecreatefrompng("template.png");
$y = 15; //vertical position of text
foreach($arrText as $arr)
{
    $white = imagecolorallocate($im,0,0,0); //sets text color
    imagestring($im,5,15,$y,trim($arr),$white); //create the text string for image,added     trim() to remove unwanted chars
    $y = $y+20;

}
imagepng($im);
imagedestroy($im);
?>

请试试这个： -

记住：为字体设置正确的路径 $font = 'arial.ttf'; 

    header('Content-type: image/png');

    // Create the image
    $im = imagecreatetruecolor(400, 30);

    // 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, 399, 29, $white);

    // The text to draw
    $text = 'go to school go to school go to school go to school go to school go to school go to school go to school go to school go to school go to school';

   // Replace path by your own font path
    $font = 'arial.ttf';

    // Add some shadow to the text
    imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);

    // Add the text
    imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

    // Using imagepng() results in clearer text compared with imagejpeg()
    imagepng($im);
    imagedestroy($im);

尝试打开抗锯齿：

imageantialias($im, true);

这会让它看起来更好吗？

或者尝试使用 truetype 字体的 imagettftext：

imagettftext ( $im, 15, 0, 15, $y, $white, 'fontfile.ttf', trim($arr));
