Bug description:'mysql_fetch_array' numeric index results corrupted for SELECT numeric.
Description:
------------
The function 'mysql_fetch_array()' should (by default) return an array
with a numeric index, and a column name index.
A query which includes a "SELECT number" - e.g. "SELECT 1234" in any
column corrupts the index count for subsequent columns.
Test script:
---------------
$qTemp = mysql_query( "SELECT a, b, c FROM test" );
$rTemp = mysql_fetch_array( $qTemp );
print_r( $rTemp );
Result:
Array
(
[0] => apple
[a] => apple
[1] => banana
[b] => banana
[2] => cherry
[c] => cherry
)
(Correct)
But, change the query to: "SELECT 7000, a, b, c FROM test" and the
resultant 'print_r' is now:
Array
(
[0] => 7000
[7000] => 7000
[7001] => apple
[a] => apple
[7002] => banana
[b] => banana
[7003] => cherry
[c] => cherry
)
This is wrong. The "SELECT 7000" has polluted the numeric index. If you
use "SELECT a, b, 7000, c" - the index from the 3rd column onwards then
gets polluted.
The same code above works perfectly under PHP 5.4.3 - but produces the
incorrect result above with PHP 5.6.9
