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
