Error suppression

[Joshua Beall]

Hi All,

I know that I can prepend functions with an '@' character in order to get
them to not output any errors, but I am wondering is there any way for a
function that I write to know if it has been called with the '@' character?
Then I can decide how errors are supposed to be handled. E.g., I could have
them emailed or logged, instead of echoing them to the screen.

Is this possible?

Use the return value of the error_reporting ().

<?php
function user_function() {
$err = error_reporting (E_ALL); // or simply error_reporting ()
// to not change it but get the
// the current value anyway
if ($err == 0) {
/* whatever, function was probably called with an '@' */
}
// rest of script
error_reporting ($err);
}
?>

Placing the line:

<?php error_reporting (0); ?>

....at the top of all of your pages (or, preferably, in an include file
referenced by all pages) will turn error reporting off completely.
Then you're free to put your own error-checking routines in (though
you have to be careful, because if you miss a condition, it can be
very difficult to debug problems).

You can also use:

<?php error_reporting (E_ALL); ?>

....during development to debug your code.
