Question

我会更改5到50 100保存但结果不会改变任何东西每次只显示小文本以及如何更改字体和$string = $user['name'];这行打印全名我们只想要fb graph api的名字请帮助。

我的代码如下：

$barcode1 = imagecreatefrompng($image_bg);
            imagecopy($fullimage, $im1, 35, 74, 0, 0, 365, 317);
            imagecopyresampled($fullimage, $barcode1, 0, 0, 0, 0, imagesx($fullimage), imagesy($fullimage), imagesx($barcode1), imagesy($barcode1));

$color = imagecolorallocate($fullimage, 0, 0, 0);
$string = $user['name'];
$fontSize = 5;
$x = 95;
$y = 344;
$font = 'arial.ttf';

imagestring($fullimage, $fontSize, $x, $y, $string, $color);

$imagename = date("Ymd") . uniqid() . uniqid() . uniqid() . '.jpg';
imagejpeg($fullimage, 'Apps/If_You_Produce/123321/' . $imagename, 100);

$values['user_id'] = $userid;
$values['image_name'] = $imagename;
$db->insert($db_table_name, $values);

您无法使用10,50,100 - http://php.net/manual/en/function.imagestring.php

仅限1-5（默认情况下）

更新

为了能够完全控制您可能想要使用的字体大小http://php.net/manual/en/function.imagettftext.php

示例（来自同一网站）：

<?php
// Set the content-type
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 = 'Testing...';
// 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);
?>
