#30238 [NEW]: string concatenation with . terminates while using ternary ? operator

From: kossarev at hytti dot uku dot fi Operating system: Windows 2000 PHP version: 4.3.9RC3 PHP Bug Type: Zend Engine 2 problem Bug description: string concatenation with . terminates while using ternary ? operator Description: ------------ Firstly, thank you for developing the great and powerful PHP language. And the bug: consider the following code.. (from next box) the first . operation terminates prematurely while using the ternary operator at the end of the statement. so i have to use a version commented out by /* */ Reproduce code: --------------- for ($i=2; $i<=$loop_count; $i++) { //bug is in the first statement: $query_string .= $dest_fields[$i-1][0]." = '".$init_array[$i]."'".($i<$loop_count)?(", "):(" ");*/ //so i have to use this version: /*$query_string .= $dest_fields[$i-1][0]." = '".$init_array[$i]."'"; $query_string .= ($i<$loop_count)?(", "):(" ");*/ } Expected result: ---------------- i expect concatenation operation to use values in $dest_fields and $init_array[, which contain simple string values (database columns and respective fields): user_id = '225', last_edit = '2004-09-26 04:08:40', language_id = '1', title = 'dfdfdsfdsa', province_id = '1', locality = 'Monako', selftype_id = '1', searchedtype_id = '1', purpose_id = '2', submenu_id = '0', messagetext = 'adsf öfdsölkfdasökfdök jöa' Actual result: -------------- using a 1-line statement version, i only get the result of ternary comparison in the resulting $query_string: , , , , , , , , , , , somehow values in $dest_table and $init_array[$] get skipped.. i suspect that presence of a ? ternary operator causes the string concatenation with . to exit prematurely. it however works when devided into two lines of code (commented out in the code example) -- Edit bug report at http://bugs.php.net/?id=30238&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30238&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30238&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30238&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30238&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30238&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30238&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30238&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30238&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30238&r=support Expected behavior: http://bugs.php.net/fix.php?id=30238&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30238&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30238&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30238&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30238&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30238&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30238&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30238&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30238&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30238&r=mysqlcfg
