Question

How can I handle an exception happening in a foreach loop?

I want to throw my exception if the for loop didn’t work properly.

As data is huge, foreach exits because PHP’s memory limit is exceeded.

try
{
 foreach()
}catch (exception $e)

{
echo $e;
}

This is not working. How do I throw an exception?

Answer 1

Memory exceeded is a fatal error, not an exception and cannot be handled with try/catch blocks.
What you need is set_error_handler.

EDIT: If that does not work you can use register_shutdown_function as a last resort and check if the script was stopped by and error.
