/* Inherited properties */
protected string $message ;
protected int $code ;
protected string $file ;
protected int $line ;
/* Methods */
public __construct ([ string $message = "" [, int $code = 0 [, int $severity = 1 [, string $filename = __FILE__ [, int $lineno = __LINE__ [, Exception $previous = NULL ]]]]]] )
final public int getSeverity ( void )
/* Inherited methods */
final public string Exception::getMessage ( void )
final public Exception Exception::getPrevious ( void )
final public mixed Exception::getCode ( void )
final public string Exception::getFile ( void )
final public int Exception::getLine ( void )

Examples

Example #1 Use set_error_handler to change error messages into ErrorException.

<?php
function exception_error_handler($errno$errstr$errfile$errline ) {
    throw new 
ErrorException($errstr0$errno$errfile$errline);
}
set_error_handler("exception_error_handler");

/* Trigger exception */
strpos();
?>

The above example will output something similar to:

Fatal error: Uncaught exception 'ErrorException' with message 'Wrong parameter count for strpos()' in /home/bjori/tmp/ex.php:8
Stack trace:
#0 [internal function]: exception_error_handler(2, 'Wrong parameter...', '/home/bjori/php...', 8, Array)
