How to turn off php error log

In the process of PHP development, we often need to turn on the PHP error log to help us troubleshoot code problems. But in some specific cases, we may also choose to turn off PHP's error log. This article will introduce how to turn off PHP's error log, let's learn about it together.

1. Why should you turn off PHP’s error log?

During the development process, the purpose of turning on the PHP error log is to promptly discover code problems and make adjustments. However, in some cases, we may not need to record error logs, such as:

1. Website in a production environment: In a production environment, turning on error logs will occupy the server's storage space and write input speed, making the website run slower. If the website is running stably, we probably don't need to log errors.
2. Some low-level errors: Some low-level errors, such as entering a non-existent file name, will be logged. At this time, we can avoid recording these useless error logs by masking error messages.
3. Specific development environment: For example, in some experimental projects, during the experiment, we need to operate the output of the error log. At this point, turning off PHP's error logging may provide us with some advantages.

The above are some situations where we may need to turn off the PHP error log. Next, we will introduce how to turn it off.

2. How to turn off PHP error log?

There are many ways to close the PHP error log. This article will introduce two common methods.

1. Modify the php.ini file

You can modify it by finding the php.ini file in the PHP installation directory. The specific steps are as follows:

(1 ) Find the line with log_errors = On in the file and change it to log_errors = Off.

(2) Change error_reporting to E_ALL & ~E_NOTICE.

(3) Save the modified configuration file.

It should be noted that modifying the php.ini file may affect the error log output of the entire system. Therefore, before making modifications, be sure to back up the configuration file and confirm whether modifications can be made.

2. Manual operation in the code

Manually close the PHP error log in the code, which can be achieved through the following code:

error_reporting(0);

In the PHP code Add the above code to turn off error reporting. This method can turn off error logging for specific problems during development and does not require changes to PHP's global configuration.

It should be noted that this code only switches the PHP error log on and off. If you need to close other types of logs, you need to modify the relevant configuration files.

3. Summary

In the process of developing PHP websites, error logs are very important for us to solve code problems in a timely manner. But in some cases, we need to turn off the error log. This article introduces two common methods to turn off PHP's error log. I hope it will be helpful to everyone. Whether the PHP error log is turned on or off, we need to understand its scope of impact and perform backup work to avoid impact on the entire system.
