PHP Bug Type: PostgreSQL related
Bug description: implode giving wrong results
Description:
------------
A Postgresql query returns an array. If the array is imploded each
value in the original array appears twice in the implosion.
Assume a Postgresql result array contains $array[0], $array[1],
$array[2];
$x=implode ('|', $array) puts
$array[0]|$array[0]|$array[1]|$array[1]|$array[2]|$array[2] into $x.
$x=$array[0]. '|' . $array[1]. '|' . $array[2]; works fine.
Why is there a difference?
Reproduce code:
---------------
<?php
$company;
$details;
$index;
require_once('../functions/sql_functions.inc');
database_connect();
$db_query = "SELECT * FROM
company ORDER BY id ";
database_query(__FILE__, __LINE__);
if ($db_rows == 0) echo $DB_EMPTY_FILE;
else {
for ($index=0; $index<$db_rows; $index++) {
$details =
pg_fetch_array($db_result, $index);
$company[$index] = implode('|', $details); } //THE BUG IS
HERE// $details =
implode('^', $company);
echo "$details"; }
Expected result:
----------------
I expected to see:
$company[$index] = $details[0]|$details[1]|$details[2].
Actual result:
--------------
Actual result:
$company[$index] =
$details[0]|$details[0]|$details[1]|$details[1]|$details[2]|$details[
2].
This program was working fine until I changed
$company[$index] = $details[0]. '|' . $details[1]. '|' . $details[2];
to
$company[$index] = implode('|', $details);
