Using if/else & a for loop in PHP to extract from XML file

Question

I'm trying to retrieve data from an XML file using PHP and keep returning the same data in my xml file, regardless of what variable it is. I realise it should be in a loop.

I've been trying to get it to go into a loop but then the code doesn't seem to work. There doesn't seem to be any great examples on the web of combined if/else statements in a for loop. Anyone know of a quick work round? Thank you.

$xml=simplexml_load_file("images/database.xml") or die("Error: Cannot create object");
if ($word = 'Agitated') {
echo $xml->programme->mood['Agitated'] . "<br>";
echo $xml->programme->name . "<br>";
echo $xml->programme->description . "<br>";

}
else {
echo $xml->programme->mood['Calm'] . "<br>";
echo $xml->programme->name . "<br>";
echo $xml->programme->description . "<br>";
}

A cursory google search yielded a few pages with great examples of using for loops to navigate XML. Take the top result which is from here in SO Loop through an XML object with SimpleXML — Luke

You only have one equal sign (=) inside your if, you need two for comparison (==).

But your logic is wrong, if you want to loop, you need a while, for, foreach and any other iterator function
