How to distinguish between array and non-array output - php

Question

I'm working on a way to pull a list of files from a query and am having trouble when the query returns more than one file.
<?php
error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
ini_set('display_errors',1);
static $fileCount = 0;
date_default_timezone_set('UTC');
ob_start();
$soapClient = new SoapClient("https://ip_address:8443/CDRonDemandService/services/CDRonDemand?wsdl",
array("login" => "login","password"=> "password","trace" => true, "cache_wsdl" => WSDL_CACHE_NONE));
echo '<pre>';
//THIS LINE IS FOR A MANUAL PULL OF THE LIST. ENTER THE START AND END DATES AS NEEDED
$data = $soapClient->get_file_list("beginning_range","end_range","1");
//If $data only contains one object, execute this;
if (count($data) === 1)
{
var_dump($data);
$name = $data->FileName;
echo '<tr><td>'. $name .'</td></tr>';
$fileCount = '1';
}
//Otherwise, execute this if $data contains any other number
else
{
sort($data->FileName);
var_dump($data);
foreach($data->FileName as $name)
{
echo '<tr><td>' . $name . '</td></tr><br>';
$fileCount++;
}
}
echo "<TABLE>";
$content = ob_get_clean();
echo "Number of CDR Files <b>" . $fileCount . "</b><br />";
echo $content;
?>
This code works okay when the output of a query contains a single file. This is the output;
object(stdClass)#2 (1) {
["FileName"]=>
string(40) "file_1"
}
file_1
But when the output contains multiple files (an array), this is the output;
object(stdClass)#2 (1) {
["FileName"]=>
array(2) {
[0]=>
string(40) "file_1"
[1]=>
string(40) "file_2"
}
}
Notice: Array to string conversion in /var/www/test.php on line 49
Array
If I remove the code in the if statement and leave only the code in the else statement, I'm able to pull the list of files;
object(stdClass)#2 (1) {
["FileName"]=>
array(2) {
[0]=>
string(40) "file_1"
[1]=>
string(40) "file_2"
}
}
file_1
file_2
It looks to me that the If/Else structure isn't right, but I'm not sure how to go about correcting it. Also, the var_dump statements are only there for troubleshooting, to show that I am actually pulling information, I will remove it later. Any help is appreciated.

Answer 1

Looks like count($data) is always equal to 1. You're trying to access an array with $data->FileName. Which is throwing the error
if (count($data)) {
if(is_array($data->FileName)) {
foreach($data->FileName as $name) {
echo '<tr><td>' . $name . '</td></tr><br>';
$fileCount++;
}
} else {
echo '<tr><td>'. $data->FileName .'</td></tr>';
$fileCount++;
}
} else {
echo "no files!";
}

Answer 2

Maybe it will work if you change
if (count($data) === 1)
to
if (count($data->Filename) === 1)

Answer 3

change this:
if (count($data) === 1) { ... }
to this:
if ( is_array($data->Filename) ) { ... }
