PHP Bug Type: Arrays related
Bug description: String '0' not handled correctly in foreach
Description:
------------
The string, '0', is not handled correctly
in a foreach loop (and possibly elsewhere).
The first loop executes correctly. The
second and third loops perform incorrect
comparisons.
In loops two and three, '0' == 'NOLIMIT'
evaluates to true when it should be false.
Reproduce code:
---------------
$arr = array('0' => '$0',
'1000' => '$1,000',
'2000' => '$2,000',
'3000' => '$3,000',
'NOLIMIT' => 'NO LIMIT');
foreach ($arr as $key => $value)
{
echo "$key : $value $hi\n";
}
echo "\n";
foreach ($arr as $key => $value)
{
if ($key == 'NOLIMIT') { continue; }
echo "$key : $value $hi\n";
}
echo "\n";
foreach ($arr as $key => $value)
{
$hi = ($key == 'NOLIMIT' ? 'hi' : '');
echo "$key : $value $hi\n";
}
Expected result:
----------------
0 : $0
1000 : $1,000
2000 : $2,000
3000 : $3,000
NOLIMIT : NO LIMIT
0 : $0
1000 : $1,000
2000 : $2,000
3000 : $3,000
0 : $0
1000 : $1,000
2000 : $2,000
3000 : $3,000
NOLIMIT : NO LIMIT hi
Actual result:
--------------
0 : $0
1000 : $1,000
2000 : $2,000
3000 : $3,000
NOLIMIT : NO LIMIT
1000 : $1,000
2000 : $2,000
3000 : $3,000
0 : $0 hi
1000 : $1,000
2000 : $2,000
3000 : $3,000
NOLIMIT : NO LIMIT hi
I am using PHP 5.03 and Apache 2.0.53 on Windows XP, service patch 2.
