PHP Safe Mode was a security feature in PHP versions prior to 5.4 that restricted certain actions that could be performed by PHP scripts. It was designed to prevent malicious scripts from accessing system resources or executing arbitrary commands. Safe Mode was considered a useful security measure in its time, but it also had some drawbacks. For example, it could make it difficult to develop and debug PHP applications, and it could break legitimate scripts that relied on certain features that were restricted by Safe Mode. As a result, Safe Mode was eventually deprecated and removed from PHP in version 5.4.
There are a few ways to check if PHP Safe Mode is on. One way is to use the phpinfo() function. This function displays information about the PHP configuration, including whether Safe Mode is enabled. If Safe Mode is on, the output of phpinfo() will include a line that says “safe_mode = On”. Another way to check if Safe Mode is on is to use the ini_get() function. This function retrieves the value of a configuration option. To check if Safe Mode is on, you can use the following code:
