#48015 [NEW]: implode giving wrong results

From: blackmagic at computer dot org Operating system: Centos 5.3 PHP version: 5.2.9 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); -- Edit bug report at http://bugs.php.net/?id=48015&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48015&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48015&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48015&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48015&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48015&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48015&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48015&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48015&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48015&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48015&r=support Expected behavior: http://bugs.php.net/fix.php?id=48015&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48015&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48015&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48015&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48015&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48015&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48015&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48015&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48015&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48015&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48015&r=mysqlcfg
