php 验证码报错Call to undefined function imagecreatetruecolor() 多种方法无效
刚学PHP 弄那个验证码的 我在网上找了好多

调试都统一报错

Call to undefined function imagecreatetruecolor()

我去查了下 


;extension=php_gd2.dll
在php.ini中去掉前边的;
然后将php目录中的ext下的php_gd2.dll拷入c:\windows\system32,重启apache

我弄了 电脑也重启好多遍了 还是不行

偶然看到说可能是GD库的问题 找地址下载 却都不是XP系统的

望高人指点 谢谢

------解决方案--------------------
基本上应该是gd2.dll扩展没有正常的支持.
换个php版本
------解决方案--------------------
wamp更简单 点击wamp图标 选择 php settings-> php extensions->php_gd2 点下 前面有个小三角就表示有启动
然后会自动重启apache 用 phpinfo()看下有没有GD扩展
------解决方案--------------------
可能是该的配置文件不对。wamp的php.ini配置文件要通过它的菜单改,不是php目录那个,是在apache下的。
------解决方案--------------------
gds32.dll 存在吗?
------解决方案--------------------
1.会不会是版本太低了?不支持该方法
2.gd2.dll不存在改文件,如果木有就网上下载一个
3.php.ini文件 查找 ;extension=php_gd2.dll ,把前面的分号去掉,如果没有这句就加个(当然不要带分号,分号是注释掉的意思)然后保存退出。

没有打开gd库,做法:php.ini文件 查找 ;extension=php_gd2.dll ,把前面的分号去掉
