#41176 [NEW]: User defined function return incorrect characters

From: ian at avionwbt dot co dot uk Operating system: Win 2003 Web Edition IIS6 PHP version: 5.2.1 PHP Bug Type: CGI related Bug description: User defined function return incorrect characters Description: ------------ The comma-separated return string from a user-defined function sometimes (about 20%, erratically) returns a pipe ('|') separated return string instead of a comma-separated string. The function works through a two-dimensional array, applying scaling factors to some elements and returning the modified first-dimension array. The example code below has been abbreviated by removing conditional (if-else) blocks for simplification. This problem has been traced by writing the return out to a log file, clips of which are listed below. This code worked fine in PHP 4, but became erratice after upgrade to PHP5. Note also that following upgrade to PHP 5 that the code failed fatally until the "if(!function_exists('calcPrice')){" condition was added. Reproduce code: --------------- if(!function_exists('calcPrice')){ function calcPrice($prod){ global $vat; global $cFactor; global $lessonData; $curr = $lessonData[$prod]['currentPrice']; $name = $lessonData[$prod]['name']; $v = ($curr*$lessonData[$prod]['netVATrate'])*0.01; $p0 = $cFactor * ($curr+$v); return ( "$prod,$p0,$curr,$name,0"); } } } foreach($lsnArray as $value){ # $lsnArray is external $p = calcPrice($value); # For reasons which escape me entirely, the # function calcPrice() periodically returns # a string with '|' separators instead of ',' !!!!!! $item = str_replace( "|", ",",$p); # work-around solution $pricelist .= "&$value=$item"; # Required URL-encoded output fwrite($LOG, "\r\nPricelist element: $value=$p"); # TRACE Expected result: ---------------- Log file clip, achieved about 80% of instances (erratic): Pricelist increment: INTR=INTR,0,0.00,Introduction to Tutor,0 Pricelist increment: OV01=OV01,11.75,10.00,Overview of the PRINCE2 Pricelist increment: OV02=OV02,15.275,13.00,Principles of PRINCE2,0 Pricelist increment: BC01=BC01,12.925,11.00,Business Case,0 Pricelist increment: OR01=OR01,16.45,14.00,Project Organisation,0 Pricelist increment: PR01=PR01,29.9625,25.50,Overview of PRINCE2 Processes,0 ... etc Actual result: -------------- Log file clip, actual about 20% of instances (erratic): Pricelist increment: INTR=INTR|0|0|Introduction to Tutor|0 Pricelist increment: OV01=OV01|11.75|10|Overview of the PRINCE2 Method|0 Pricelist increment: OV02=OV02|15.275|13|Principles of PRINCE2|0 Pricelist increment: BC01=BC01|12.925|11|Business Case|0 Pricelist increment: OR01=OR01|16.45|14|Project Organisation|0 Pricelist increment: PR01=PR01|29.962|25.5|Overview of PRINCE2 Processes|0 ... etc -- Edit bug report at http://bugs.php.net/?id=41176&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41176&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41176&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41176&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41176&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41176&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41176&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41176&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41176&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41176&r=support Expected behavior: http://bugs.php.net/fix.php?id=41176&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41176&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41176&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41176&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41176&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41176&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41176&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41176&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41176&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41176&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41176&r=mysqlcfg
