读者您好：

可将运行之后的结果截图发上来，便于我们帮你分析和解决问题。

$结果集=mysql_query("select * from 字符表");
$某行=mysql_fetch_array($结果集);

这部分的代码，从数据库查询完字符表之后，没有进行while循环吗？是否可将实际代码粘贴上来？

SET FOREIGN_KEY_CHECKS = 0;

DROP TABLE IF EXISTS  `zi_fu_biao`;
CREATE TABLE `zi_fu_biao` (
  `id` int(30) NOT NULL AUTO_INCREMENT,

insert into `zi_fu_biao`(`id`,`zi_fu`,`zi_fu_da_xiao`,`zi_fu_jiao_du`,`zi_fu_heng_zhou_wei_zhi`,`zi_fu_zong_zhou_wei_zhi`,`zi_ti`) values

<?php
require '../../../../../public_file/database_connection.php';
$jie_guo_ji=mysql_query("select * from zi_fu_biao");
$mou_hang=mysql_fetch_array($jie_guo_ji);

$a=$mou_hang['zi_fu_da_xiao'];

$f=$mou_hang['zi_fu'];


$hua_bu= imagecreate(5120,4862);             
imagecolorallocate($hua_bu, 255,255,255);
$qian_jing_yan_se=imagecolorallocate($hua_bu,0,0,0);

imagettftext($hua_bu,$a,$b,$c,$d,$qian_jing_yan_se,$e,$f);

header("content-type:image/png");   
imagepng($hua_bu);      
imagedestroy($hua_bu);  
?>

我怀疑是数据引入，好像要使用$_GET[ ]
php gd函数不能与mysql一起使用

<?php    
require '../../../../../public_file/database_connection.php';
$结果集=mysql_query("select * from 字符表");
$某行=mysql_fetch_array($结果集);
$a=$某行['字符大小'];
$b=$某行['字符角度'];
$c=$某行['字符横轴位置'];
$d=$某行['字符纵轴位置'];
$e=$某行['字体'];
$f=$某行['字符'];
?>
<img src="cha_kan_xiao_guo2.php?字符大小=<?php echo $a ?>&字符角度=<?php echo $b ?>&字符横轴位置=<?php echo $c ?>&字符纵轴位置=<?php echo $d ?>&
字体=<?php echo $e ?>&
字符=<?php echo $f ?>"  alt=""/>

<?php    
$画布 = imagecreate(5120,4862);             
imagecolorallocate($画布, 255,255,255);
$前景颜色=imagecolorallocate($画布,0,0,0);  
$a=$_GET['字符大小'];
$b=$_GET['字符角度'];
$c=$_GET['字符横轴位置'];
$d=$_GET['字符纵轴位置'];
$e=$_GET['字体'];
$f=$_GET['字符'];
imagettftext($画布,$a,$b,$c,$d,$前景颜色,$e,$f);
header("content-type:image/png");   
imagepng($画布);      
imagedestroy($画布);  
?>

这两个文件合在一起可以运行
