Class synopsis

/* Properties */

protected int $severity ;

/* Methods */

public __construct ([ string $message [, int $code [, int $severity [, string $filename [, int $lineno ]]]]] )

final public int getSeverity ( void )

/* Inherited methods */

final public string Exception::getMessage ( void )

final public int Exception::getCode ( void )

范例

Example #1 Turn all error messages into ErrorException.


<?php
function exception_error_handler($errno, $errstr, $errfile, $errline ) {
throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
}
set_error_handler("exception_error_handler");

/* Trigger exception */
strpos();
?>

上例的输出类似于：

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)
#1 /home/bjori/php/cleandocs/test.php(8): strpos()
#2 {main}
  thrown in /home/bjori/tmp/ex.php on line 8
