Operating system: All
PHP version: 4.3.2
PHP Bug Type: Documentation problem
Bug description: ob_start() return value type is invalid
Documentation states
void ob_start ( [callback output_callback])
In reality since 4.3.2 this function returns a boolean value. It returns
true if output buffering started successfully, and false if some problem
occured. This problem can be output callback function that does not exist.
Earlier versions of PHP started output buffering with default handler in
this case.
Code to show backward incompatibility:
<?
ob_start();
echo "AAA";
$a = ob_get_contents();
$var = ob_start("thereisnosuchfunction");
echo "BBB";
$b = ob_get_contents();
ob_end_clean();
ob_end_clean();
echo $b.'---'.$a;
var_dump($var);
?>
4.3.2 outputs
AAABBB---AAAbool(false)
earlier versions output
BBB---AAAbool(true)
