Make sure PHP is reporting all errors and warnings.
Warnings and notices are PHP’s way of letting you know that you are utilising features in a non-standard way. If your code is omitting errors, then it should be fixed as soon as possible. Strict warnings are a class of errors that are turned off by default in most PHP installations. Turning on strict warnings gives you another level of error reporting, which is helpful to prevent you from using misusing functions, making sure your code is compatible with future PHP versions.
In the example here, using date() without explicitly setting a timezone will result in an E_STRICT warning. In this case, we are using a function called strictErrors to tell PHP to report all error types.
Example
<?php
function strictErrors() {
$reporting_level = E_ALL;
// if version of PHP < 6, explicity report E_STRICT
if ( version_compare( PHP_VERSION, '6.0.0', '<' ) ) {
$reporting_level = E_ALL | E_STRICT;
}
return error_reporting( $reporting_level );
}
// turn on strict error and warnings
strictErrors();
// produces strict warning
echo date( "d-M-Y" );
// no warning
date_default_timezone_set( 'Europe/London' );
echo date( "d-M-Y" );
?>
