Function Error
Zend Server Best Practices
Description: When a specific function in your code returns FALSE, it generates an event. The “Function
Error” Rule contains a list of monitored functions (i.e. functions that when returning FALSE will trigger an
event).
Information Collected:
The most important details are:
Function Name - As displayed in the Issue’s General Details
Function Arguments - The arguments of the function that triggered the event are listed in the
Function Data tab.
Backtrace – identify what happened before the error happened that may have caused a problem
such as incorrect data or problematic input data.
In most cases, these details alone should be enough to indicate what triggered the event.
Applicable Diagnostic Actions:
