Description:
------------
When there is an error within json_encode (e.g. due to invalid utf8), E_WARNING
should be raised. However, that doesn't happen in some cases.
It doesn't happen when display_errors is set to On.
In latest snapshot of 5.4 it does not happen at all.
Test script:
---------------
<?php
/**
* WTF? Error handler is not called, when display_errors=On
*
* _errorHandler must be called in each case, but it's not.
*
* Results differ on different PHP versions.
*/
function _errorHandler($severity, $message, $file, $line, $context) {
$GLOBALS['err'] = func_get_args();
// echo "Error ($severity) $message in $file:$line\n";
}
set_error_handler('_errorHandler');
// display_errors = Off, works fine
{
ini_set('display_errors', 0);
// Calls error handler, fine
$err = NULL;
$tmp = substr(new stdClass(), 1, 1);
var_dump($err[0], $err[1]);
// Calls error handler, fine
$err = NULL;
$tmp = json_encode(array("bad utf\xFF"));
var_dump($err[0], $err[1]);
}
// display_errors = On, WTF???
{
ini_set('display_errors', 1);
// Calls error handler, fine
$err = NULL;
$tmp = substr(new stdClass(), 1, 1);
var_dump($err[0], $err[1]);
// Does NOT call error handler, WTF???
$err = NULL;
$tmp = json_encode(array("bad utf\xFF"));
var_dump($err[0], $err[1]);
}
Expected result:
----------------
int(2)
string(55) "substr() expects parameter 1 to be string, object given"
int(2)
string(49) "json_encode(): Invalid UTF-8 sequence in argument"
int(2)
string(55) "substr() expects parameter 1 to be string, object given"
int(2)
string(49) "json_encode(): Invalid UTF-8 sequence in argument"
Actual result:
--------------
On 5.4.6:
int(2)
string(55) "substr() expects parameter 1 to be string, object given"
int(2)
string(49) "json_encode(): Invalid UTF-8 sequence in argument"
int(2)
string(55) "substr() expects parameter 1 to be string, object given"
NULL
NULL
On 5.4-latest:
int(2)
string(55) "substr() expects parameter 1 to be string, object given"
NULL
NULL
int(2)
string(55) "substr() expects parameter 1 to be string, object given"
NULL
NULL
