unhandled errors in php
How can I know during runtime that my code threw a Warning?
example
try {
e开发者_StackOverflow中文版cho (25/0);
} catch (exception $exc) {
echo "exception catched";
}
throws a "Warning: Division by zero" error that i can not handle on my code.
You're looking for the function set_error_handler()
. Check out the sample code in the manual.
Make sure that you don't only suppress the error warnings, but instead silently redirect them to a log file or something similar. (This helps you track down bugs)
You need to handle the exception yourself as follows.e.g
function inverse($x)
{
if(!$x)
{
throw new Exception('Division by zero.');
}
else
{
return 1/$x;
}
}
try
{
echo inverse(5);
echo inverse(0);
}
catch (Exception $e)
{
echo $e->getMessage();
}
You need to install an error handler that converts old style php "errors" into exceptions. See an example here
