PHP Bug Type: Compile Warning
Bug description: Warning message is missing with shuffle() more than one
argument
Description:
------------
When shuffle() function is called with two arguments (ie. one argument
more than expected), it performs the operation of shuffling and donot
throws warning message stating for more than expected number of arguments ,
as we see with other functions like end() etc.
Also when shuffle() is called with zero argument(ie. one less than minimum
number of argument required) the warning message is not proper and do not
say anything about the insufficient number of arguments.
The following can be added in the beginning of the function definition for
PHP5 to check for the above scenarios:
if (ZEND_NUM_ARGS() != 1) {
WRONG_PARAM_COUNT;
}
Reproduce code:
---------------
<?php
$arr = array(1,2,3,4,5);
var_dump( shuffle() );
var_dump( shuffle($arr, 2) );
?>
Expected result:
----------------
Warning: Wrong parameter count for shuffle() in %s on line %d
NULL
Warning: Wrong parameter count for shuffle() in %s on line %d
NULL
Actual result:
--------------
Warning: shuffle(): could not obtain parameters for parsing in %s on line
%d
bool(false)
bool(true)
