php代码出现错误分析详解

由于最近总是接触到php，经常会出现一些错误，特把php的常见的错误代码收集了下，希望对大家有帮助。
错误类型：
一、未使用二进制上传

代码:
Fatal error: This encoded file is corrupted. Please refer to http://www.zend.com/support/support_faq.php?id=loader_file_corrupt for further help in
/webhome/****.com/web/www/index.php on line 0

二、数据表中缺少字段
代码:
An error was encountered
Boka SiteEngine
数据库错误
错误信息1054: Unknown column ‘tuijian’ in ‘where clause’
出现错误的查询信息是
SELECT * FROM boka_product WHERE tuijian=1 AND classid IN (‘1′,’0’)ORDER BY id DESC LIMIT 4

三、服务器限制了网站使用内存的大小为8M，现在已经超过
代码:
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 5898240 bytes)

四、这个是模板错误，header.php的529行所指出的模板，该模板的79行出错
[code]in /webhome/***.com/web/www/header.php(529) : eval()’d code on line 79

五、数据库表不存在
代码:
An error was encountered
Boka SiteEngine
1146: Table ‘test.boka_settings’ doesn’t exist

SELECT value FROM boka_settings WHERE variable=’defaultstyleid’

六、 未安装或者数据库的用户名密码错误
代码:
An error was encountered
Boka SiteEngine
1045: Access denied for user: ‘root@localhost’ (Using password: YES)

七、查询语句有错误
代码:
Boka SiteEngine
数据库错误
错误信息1064: You have an error in your SQL syntax near ‘ORDER BY sequence ASC,id ASC’ at line 1
出现错误的查询信息是
UPDATE gzhy_newsclass SET ishidden =’1′ WHERE id = ’38’ ORDER BY sequence ASC,id ASC

八、文件过期
代码:
There is a fatal error,the file has expired

九、数据库出错，需要修复数据库或者重新启动数据库？
代码:
An error was encountered
Boka SiteEngine
2002: Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

十、代码:
Warning: Unexpected character in input: ‘’ (ASCII=4) state=1 in c:\program files\siteengine\siteenginephp\www\index.php on line 97
Warning: Unexpected character in input: ‘’ (ASCII=5) state=1 in c:\program files\siteengine\siteenginephp\www\index.php on line 97
Parse error: parse error, unexpected T_STRING in c:\program files\siteengine\siteenginephp\www\index.php on line 97

十一、这是语言管理中的language表里面有些字段没有引号，有些新增模块有这样的问题
代码:
Boka SiteEngine
数据库错误
错误信息1064: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near ‘home’]” at line 1

出现错误的查询信息是
UPDATE boka_language
十二、不存在此函数
代码:
Fatal error: Call to undefined function: buildhtml() in /usr/boka/www.lzj.bsa.cn/admin/news.php on line 894

十三、服务器执行时间超时.修改php.ini里的设置
代码:
Fatal error: Maximum execution time of 30 seconds exceeded in c:\program files\siteengine\siteenginephp\www\lib\tar.php on line 101 Fatal error: Maximum execution time of
30 seconds exceeded in c:\program files\siteengine\siteenginephp\www\lib\cookie.php on line 174

十四、调用了不存在的类
代码:
Fatal error: Call to a member function on a non-object in e:\boka\d.com\admin\product.php on line 1291

十五、ZEND版本不匹配？
代码:
Fatal error: Incompatible file format: The encoded file has format ID 2006022801, whereas the Optimizer can read up to 2002062301 in e:\website\d.com\install.php on line 0

十六、不能建立windows下的Mysql服务进程
代码:
cannot create windows service for mysql.error:0

十七、数据表错误，修复数据表.(检查数据库的表。通过phpmyadmin即可修复)
代码:
Discuz! info: MySQL Query Error
User: 球球妈
Time: 2006-7-26 10:50am
Script: /forums/redirect.php
SQL: SELECT f.fid, t.tid, f.*, ff.* , f.fid AS fid
FROM cdb_forums f, cdb_threads t
LEFT JOIN cdb_forumfields ff ON ff.fid=f.fid
WHERE t.tid=’109118′ AND t.displayorder>=’0′ AND f.fid=t.fid LIMIT 1
Error: Can’t open file: ‘cdb_threads.MYI’. (errno: 145)
Errno.: 1016
Similar error report has beed dispatched to administrator before.

十七，环境zend未安装
代码:
Zend Optimizer not installed

十八，安装是没有任何反应，输入install.php面空白。
环境错误提示被屏蔽，察看文件是否用二进制传送或者是zend是否有安装。
十九、数据库出现
代码: [拷贝到剪贴板]
too many connections

数据库链接数太多，修改mysql的最大链接数。
二十、输入安装install.php提示
install.php 不允许执行原因是：
脚本权限错误：不能设置为同组可写！
服务器端配置：
Server Administrator/Contact: [no address given]
Server Name: www.***.com
Server Port: 80
Server Protocol: HTTP/1.1
访问请求数据：
User Agent/Browser: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon)
Request Method: GET
Remote Address: 221.222.177.106
Remote Port: 30066
请检查install.php的文件属性是否为644。
二十一、访问页面提示：
代码:
Warning: main(/data/home/zn00s1/htdocs/data/language/.php): failed to open stream: No such file or directory in /data/home/zn00s1/htdocs/admin/global.php on line 62

这个错误是由于数据库恢复不正常。请核实2个数据库的版本是否一致。
二十二、在2003下执行install.php文件，点击”下一步”的按钮点击不下去.
请检查2003下的IE的安全设置为中。
