PHP version: Irrelevant
PHP Bug Type: Documentation problem
Bug description: print_r, var_export, debug_print_backtrace use output
buffering
Description:
------------
It needs to be documented that print_r and var_export, with the second
parameter TRUE, internally use output buffering to return their result
rather than output it.
This causes them to fail when used within an output buffering callback
handler.
Alternatively, this could be changed to a feature request and the code
could be changed to not use output buffering.
Reproduce code:
---------------
<?php
function ob_handler( $in ) {
return var_export( $in, true );
}
ob_start( 'ob_handler' );
echo "Hello";
?>
Expected result:
----------------
'Hello'
Actual result:
--------------
Fatal error: var_export(): Cannot use output buffering in output buffering
display handlers in Command line code on line 2
