PHP Error

Description: When a specific PHP error is reported, it generates an event. The “PHP Error” Rule contains a list of monitored PHP error types. This event type complements the error_reporting settings in your php.ini by reporting specific errors even if they are set to disabled in your php.ini..

Information Collected:

The most important details are:

Function Name - As displayed in the Issue’s General Details
Error Data - Listed in the Error Data tab.
Backtrace – to investigate what function calls were executed just before the error was reported.
In most cases, these details alone should be enough to indicate what happened to trigger an event.

Applicable Diagnostic Actions:

Click on a link to see how to perform each action tools are listed in order of relevance to helping solve the event:

Run the Debugger
Open code in editor
Redefine database queries
View information in the Logs

Possible Causes and Solutions:

Syntax/Parse Errors - missing or incorrect syntax in code that is found during PHP compilation

Fatal Runtime Errors - such as E_WARNING and E_ERROR - indicate that there was a call to an undefined function or that you did not load a specific extension or when classes and Functions are defined twice. Possible Solution: Open code and view Line and function that triggered the error.

Uncaught Exceptions - generate fatal errors, with a complete backtrace to trace the reason why the PHP error was reported.

Runtime Warnings - The code did not run as expected. Normally a notice is displayed and the code continues to run in an unexpected manner or the code will crash. Possible solutions: check your code for the following wrong DB QUERIES missing FILES, STREAMS functions that are performing DIV BY ZERO
