Bug description: array_fill() function's inconsistent behavior in PHP5 and PHP6
Description:
------------
1) In php 5 when following values are given as value for $start_key, the
values
are not automatically converted and used,A warning message is displayed.
However
automatic conversion of these values happen in php6 and the converted
values are
used, hence no warning messages generated.
The $start_key values are :
null, NULL, true, false, TRUE, FALSE.
The warning message generated in php5 is :
Warning: array_fill(): Wrong data type for start key in %s on line %d
bool(false)
2) In php6 when empty string("" & '') is given as $start_key the
array_fill()
function generates an warning however in php5 it doesn't. conversion
happens
and the value is used.
The warning message generated in php6 is :
Warning: array_fill() expects parameter 1 to be long, string given in %s
on line 3
NULL
Please note that documentation doesn't say any thing in specific for these
but looking at
array type documentation(
http://in.php.net/manual/en/language.types.array.php ),
an array could have any of these as key. Since this function is doing the
creation of
an array with specified values, it should create array in all possible
ways,
that can be created in general using array(). If not, then one would have
to write
an work-around code when these value are to be passed to array_fill().
Reproduce code:
---------------
1) null and boolean values as $start_key
<?php
var_dump( array_fill(TRUE, 2, 100) );
var_dump( array_fill(NULL, 2, 100) );
?>
2) empty string value as $start_key
<?php
var_dump( array_fill("", 2, 100) );
?>
Expected result:
----------------
1) null and boolean values as $start_key
array(2) {
[1]=>
int(100)
[2]=>
int(100)
}
array(2) {
[0]=>
int(100)
[1]=>
int(100)
}
2) empty string value as $start_key
array(2) {
[0]=>
int(100)
[1]=>
int(100)
}
Actual result:
--------------
1) null and boolean values as $start_key
on php5:
Warning: array_fill(): Wrong data type for start key in %s on line %d
bool(false)
Warning: array_fill(): Wrong data type for start key in %s on line %d
bool(false)
on php6:
array(2) {
[1]=>
int(100)
[2]=>
int(100)
}
array(2) {
[0]=>
int(100)
[1]=>
int(100)
}
2) empty string value as $start_key
on php6:
Warning: array_fill() expects parameter 1 to be long, string given in %s
on line %d
NULL
Warning: array_fill() expects parameter 1 to be long, string given in %s
on line %d
NULL
on php5:
array(2) {
[0]=>
int(100)
[1]=>
int(100)
}
