非静态方法 PEAR::isError() 不应静态调用 [英] Non-static method PEAR::isError() should not be called statically
问题描述
从 RHEL 5x 升级到 CentOS 6x 后，我开始在 httpd 日志中看到这些错误:
After upgrading from RHEL 5x to CentOS 6x, I started seeing these errors in my httpd log:
PHP 严格标准:非静态方法 PEAR::isError() 不应该在第 33 行的/web/sites/blah/somescript.php 中静态调用
PHP Strict Standards: Non-static method PEAR::isError() should not be called statically in /web/sites/blah/somescript.php on line 33
我看到了 MDB2 的类似错误.稍后会详细介绍.
I saw similar errors for MDB2. More on that in a sec.
somescript.php:
somescript.php:
32 $mdb2_dbx = MDB2::factory($dsn_mdb2, $mdb2_options);
33 if (PEAR::isError($mdb2_dbx))
34 {
35 $err = '<p>Cannot connect to database: ' . $mdb2_dbx->getMessage();
36 errorHandler($err);
37 }
我做的第一件事是编辑 /etc/php.ini 并添加 &~E_STRICT 到错误报告.重新启动 httpd 以加载新配置.仍然收到这些错误消息.
The first thing I did was edit /etc/php.ini and add & ~E_STRICT to error reporting. Restarted httpd to load the new config. Still getting these error messages.
其他人提到了与 MDB2 相同的问题，因此我将这些包更新到了测试版.这似乎解决了 MDB2 错误，但我仍然在 httpd 日志文件中收到 PEAR 错误消息.
Others mentioned the same problem with MDB2, so I updated these packages to the beta releases. This seemed to address MDB2 errors, but I'm still getting the PEAR error messages in httpd log file.

问题
是否有不同的调用 PEAR::isError() 方法不会产生错误?
Is there a different way of invoking PEAR::isError() that will not produce errors?
推荐答案
不，没有.PEAR::isError 继承自 PHP 4 次.
No there isn't. PEAR::isError is legacy from PHP 4 times.
如果在 php.ini 中改变错误级别还不够，你应该检查
If changing the error level in php.ini is not enough you should check
- 是否正在加载另一个 php.ini 文件(通过 Apache 检查 phpinfo() 输出)
- 某些脚本设置了错误级别.
如果所有这些都没有帮助，请在运行时使用 error_level() 函数设置适当的级别，或者如果没有其他帮助，请使用 @ 抑制错误操作员.应该避免使用 @ ，因为它相对慢"(错误报告无论如何都很慢......)并且它可能隐藏其他错误.
If all that doesn't help, set an appropriate level using the error_level() function at runtime, or if nothing else helps, suppress the errors using the @ operator. Using @ should be avoided as it is relatively "slow" (error reporting is slow anyways ...) and it might hide other errors.
长期建议是使用更现代的库.
Long-term suggestion would be to use more modern libraries.
