Question

I’m writing a relatively simple if statement to process the response of a web-service

The below code will output the type of data that’s being returned and the value of it:

$response = $client->__getLastResponse();
echo $response;
echo gettype($response);

For a correct response, I get ‘true string’
For an incorrect response, I get ‘false string’

So I need an if statement to process whether it’s true or false:

if($response == "true"){
    echo "Logged In";
} else {
    echo "Not Logged In";
}

Whatever response I get, I always receive “Not Logged In”

I’ve tried the === operator also, but to no avail.

Can someone help?

Provided that’s you actual code, you have echo $response . gettype( $response ) which yields “true string”, right? If so, there’s a space after “true”. Try to trim the response:

<?php
$response = $client->__getLastResponse();
if( strtolower( trim( $response ) ) === 'true' ) {
   echo 'response is true.';
}

Apart from that, debugging is really easy using var_dump, as that will display quotes around the value and the total length of the string, making the additional space pop-up much easier to spot.
