php: please review... can't find error..

No errors, but nothing shows up on the page. I've been looking at it too long to identify the error--please review.  All this code is trying to do is return simple string values from a remote web service.


if ($_POST['zipn'] != ''){
  $zipn = (string) $_POST['zipn'];
  $client = new SoapClient("");
  $result = $client->GetSupplierByZipCode(array('izipn' = $zipn));
  // Note that $array contains the result of the traversed object structure
  $array = $result->GetSupplierByZipCodeResult->tSupplierData;

  print "
<table border='2'>

  foreach($array as $k=>$v){
    print "
        <td align='right'>" . ($k+1) . "</td>
          <td>" . $v->sSupplierNumber . "</td>
		      <td align='right'>" . $v->sCompanyName . "</td>
		      <td align='right'>" . $v->sAddress1 . "</td>
		      <td align='right'>" . $v->sAddress2 . "</td>
		      <td align='right'>" . $v->sCity     . "</td>
		      <td align='right'>" . $v->sState    . "</td>
		      <td align='right'>" . $v->sZip      . "</td>
		      <td align='right'>" . $v->sZipPlus4 . "</td>
		      <td align='right'>" . $v->sTelephone . "</td>
		      <td align='right'>" . $v->sIsSupplierParticipating . "</td>


print "</table>";
else {

Php is smart enough to understand by itself is a value is a string or a number, so you can be happy leaving Php does the work for you.

That said, your question (what is the best way...) is too vague for me. If you need more help, you should post an example of the array you need to process and say exactly what you want to get. In addition, I don't have any idea about what GetSupplierByZipCode() method does. AFAIK, your code should work fine once you fix the error mentioned above :)

This is what I do when this happens to me:

try to comment all of your code and add an echo command at the end. Something like:


all your php code here

echo 'Hi!';

you will see the message "Hi!" on the screen.

Then try to uncomment line by line until you found the error.

Another solution is to set the display mode to show errors, but some servers doesn't allow this, so on this case I use the technique I described above about commenting/uncommenting code.

Hope it helps.

Your line 6 is

$result = $client->GetSupplierByZipCode(array('izipn' = $zipn));

but should be

$result = $client->GetSupplierByZipCode(array('izipn' => $zipn));

=> instead of =

I see also a bad value for form id which should not  contain white spaces: you should modify it to "MedicareSuppliers"

@margusG -- great catches!

  $result = $client->GetSupplierByZipCode(array('izipn' => $zipn));  

I think this is the line where things go wrong, now that you spotted it-- the other method i was working with was by supplier id--which was convenient since i had an integer to work with while cycling thru an array...

What is the best way to work with this array of strings (zip codes) that look like numbers?
Paula DiTalloIntegration developerAuthor Commented:
Thanks margus--I come from the c# world -- i would have had to have create a integer/string-key pair to cycle through the array.
