I'm faced with a task to retrofit an existing application written to work within PHP 4.3.2 to work under PHP 4.1.2. The following sections fail to work under PHP 4.1.2 (description after code):
/**
* Perform mailing
*
* @access private
* @param object $result;
* @param mixed $emailTo
* @see file_get_contents
* @see file_put_contents
*/
function &mail($result, $emailTo) { // STATIC VOID METHOD
global $willUseEmailBundling, $senderEmailAddress, $isBogusSenderEmailAddress, $bundleEmailAddress, $bundleEmailFilePath, $bundleEmailFileName;
// NEW 6/29/2005: IF SOME ERROR OCCURRED SOMEWHERE THEN YOU MUST REOBTAIN THE VALUES WITHIN $preservedValuesArray
if (!$this->isSuccessful) $this->setPOSTEmailValues();
if ($this->isSuccessful) foreach ($_POST as $key => $val) if (!isset(${$key})) ${$key} = $val;
if ($this->isSuccessful && !$willUseEmailBundling) {
// SET $this->result FROM HERE, YOU WILL BE HANDLING EMAILING USING THIS RESULTSET OUTSIDE THE SCOPE OF THIS METHOD
$this->setResult($result);
} elseif ($this->isSuccessful) {
// REOBTAIN FOR $fileID
$fileID =& $this->getResource();
@fputs($fileID, $emailTo);
@fflush($fileID);
if (!file_get_contents("$bundleEmailFilePath/$bundleEmailFileName")) @file_put_contents("$bundleEmailFilePath/$bundleEmailFileName", $emailTo);
if (!file_get_contents("$bundleEmailFilePath/$bundleEmailFileName")) {
$this->isSuccessful = false;
$this->setErrorArray(array('action' => "Could not write onto bundling file \"$bundleEmailFilePath/$bundleEmailFileName\""));
}
if ($this->isSuccessful && !$this->unlock($fileID)) {
$this->isSuccessful = false;
$this->setErrorArray(array('action' => "Could not unlock resource for \"$bundleEmailFileName\""));
} else {
@fclose($fileID);
}
if ($this->isSuccessful) {
// NEW 6/29/2005: ENSURE THAT IF USING email_select() OPTION THAT SENDING TO CC AND/OR BCC IS DONE ONLY ONCE VIA BOOLEAN SESSION VAR
if (!$this->emailHandler->getHasSentCCBCC() && (${$section . '_sender_cc'} || ${$section . '_sender_bcc'})) {
$this->emailHandler->setHasSentCCBCC(true);
if (${$section . '_sender_cc'}) $cc = "\nCC:${$section . '_sender_cc'}";
if ((int)$phpVersionInt > 412 && ${$section . '_sender_bcc'}) $bcc = "\nBCC:${$section . '_sender_bcc'}";

$sender = (${$section . '_email_sender'}) ? ${$section . '_email_sender'} : $senderEmailAddress;

mail($bundleEmailAddress, ${$section . '_email_subject'}, ${$section . '_email_body'}, "From:$sender$cc$bcc\r\n");

@fputs($fileID, $data);
@fclose($fileID);
}
}
}
What is supposed to happen is that when someone submits an email to a select group of contacts, that an email bundler program set up to work within sendmail kicks in, reading the existing email addressed written into a flat file, email_bundle.txt.
However, in PHP 4.1.2 while it write onto email_bundle.txt, I keep getting error messages indicating that there is no content in email_bundle.txt, in spite of the fact that I can view the file using command line to verfiy that content is indeed found. This does not occur in PHP 4.3.2+.
Based on what you see so far, what should or could I do differently?
Thanks
Phil
