PHP version issue?

lee_sov · December 14, 2015

Hi, we've recently moved a website to a different host & now have a problem with the contact us php page. this was all working fine on the previous host & the files have been directly copied to the new host so nothing has changed.

The html part of the site is all fine but when trying to browse to the contact us php page, we receive:

500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed.

The only difference, from what I can see is the PHP version, - on the old host it was 5.3.28 & the new host is 5.2 & cannot be changed. Would that cause this issue, or is this something else altogether?

Thanks

Why would you go to a host going backwards in PHP versions? The current version is PHP 7. You need to get a new host. It is ridiculous to fix code going backwards.

benanamen is right, but if you want us to help debug your php page, we kinda need to see the code. Otherwise there is no way for us to really help;

I know I was just as surprised when they told us! We have many of our clients at the same host (123-Reg) & due to issues with the previous host we moved this one as well, just haven't had any php issues before! this is on a shared windows hosting platform & they say 5.2 is the highest version available!

Would that be the reason then for receiving this error, & is there any way around it?

Current code is here:

<?php
ini_set('display_errors', 1); 
$SENT = false;
if ($_POST && $_POST["name"] && preg_match("/^[a-zA-Z0-9 ]+$/i", $_POST["name"]) !== false && $_POST["email"] && preg_match("/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i", $_POST["email"]) !== false) { 
 
try {
  include_once('class.phpmailer.php');
    $mail = new PHPMailer();
    $mail->IsSMTP();
    $mail->Host = "smtp.gmail.com"; // place your smtp host here
    $mail->SMTPAuth = true;
    $mail->SMTPSecure = "ssl";
    $mail->Username = "mail@emailaddress.com "; // place your smtp username here
    $mail->Password = "Password"// place your smtp password here
    $mail->Port = "465";
 
    $mail->From = $_POST["email"];
    $mail->FromName = $_POST["name"];
    $mail->AddAddress("mail@emailaddress.com ");
 
    $mail->Subject = "Enquiry from the  Website";
 

 // build the email
 $s = "The following contact form has been submitted:\n\n";
 
 $s .= "=== Customer Details =====\n";
 $s .= "Name: " .$_POST["name"]. "\n";
 $s .= "Company: " .$_POST["company"]. "\n";
 $s .= "Telephone: " .$_POST["telephone"]. "\n";
 $s .= "Email Address: " .$_POST["email"]. "\n\n";
 
 $s .= "=== Enquiry Information =====\n";
 $s .= trim($_POST["comments"])."\n\n";
 
 $s.= "Generated: " .date("Y-m-d H:i:s");
 
 $mail->Body = $s;
 $mail->WordWrap = 72; // wrap text to 72 characters
 

 //  echo "Attempting to send e-mail...";
 if ($mail->Send()) {
  $SENT = true;
 // echo "Success!";
 } else {
  $SENT = false;
 //  echo "Failed!";
 }
} catch (phpmailerException $e) {
    echo $e->errorMessage();
  } catch (Exception $e) {
    echo $e->errorMessage();
  } 
}

fixing code so it doesn't break highlighting

benanamen · December 14, 2015

You have numerous problems with that code.

You are missing a quote here: $mail->Password = "Password"// place your smtp password here

Your html is all over the place incorrectly. You have two html start tags. You have several closing tags with no opening tags.

more coming.....

PHP 5.2 reached end of life back in 2011 and hasn't received any security updates ever since. Running this on a public webserver is just reckless and unprofessional.

Get a hoster which actually cares about the servers and keeps them up-to-date. The currently supported PHP versions are 5.6 and 7.

lee_sov · December 15, 2015

But is there anything in this code that would cause it not to work in php 5.2 or produce that error?

I tried enabeling error checking but it doesnt even get that far, as soon as I browse to the page i receive the internal server error...

Ch0cu3r · December 15, 2015

as soon as I browse to the page i receive the internal server error...

Tried checking your servers error logs?

lee_sov · December 15, 2015

Yes, nothing in the logs & the hosts have checked as well & can find no issues!

cyberRobot · December 15, 2015

Have you tried removing all the PHP code at the top and then adding it back a little at a time? This should help you track down the offending code.

benanamen · December 15, 2015

Did you add the missing quote I already told you about?

lee_sov · December 23, 2015

Did you add the missing quote I already told you about?

Yes the missing quote is there but the code still wont work, any other ideas?

lee_sov · December 23, 2015

Have you tried removing all the PHP code at the top and then adding it back a little at a time? This should help you track down the offending code.

I've tried taking all the php code out at the top & I still receive the 500 Internal server error so it must be something to do with the page itself, - being saved as a *.php or that the server doesn't like it maybe?

As a test, I created a blank page with nothing in it, saved it as test.php & uploaded it. As soon as I try to browse to that page I receive the same error so it must be something to do with the php file extension. As soon as I changed the file name to test.html, it worked fine...

the code you posted in this thread was broken because you made edits to it to remove information from the post and you removed at least one quote/semi-colon, which made it next to impossible to help based on the code, because we don't know what else you may have changed in it when posting it.

repost the code, literally just replacing any sensitive information with x's (you should have this type of information defined in a require'ed file using variables or defined constants anyway), but do not modify any syntax, such as quotes, semi-colons, ...

next, assuming this is a run-time error, and not a php syntax error, you should have the following three lines at the start of your php code to get all php detected run-time errors reported and displayed -

ini_set("display_startup_errors", "1");
ini_set("display_errors", "1");
error_reporting(-1);

have you tried a .php file with just something simple like the following in it -

<?php
echo 'yes php works';
?>

is there a .htaccess file that came from the old hosting? it may have some statements in it that's producing an error. however, there should be errors in the web server error log. if you do have a .htaccess file, what is the contents of the .htaccess file?

also, what was the web server type on the both the old and new hosting?
