Parse error PHP

My question is that I get a syntax error with the following code:

$query = "SELECT stad, modell FROM Biluthyrare a, Bilar b WHERE a.uthyrNr = b.uthyrNr AND stad = '".$stad"'";

The error is "Parse error: syntax error, unexpected '""' (T_CONSTANT_ENCAPSED_STRING) in ......

Any ideas?

This looks like it comes from mixing quotes. Two ways to change your query so that it will no longer throw that error are below.

The following example works because when you use double-quotes ("), you can simply add your variables in the string and the query will be formed how you intended.

<?php

$query = "SELECT stad, modell FROM Biluthyrare a, Bilar b WHERE a.uthyrNr = b.uthyrNr AND stad = '{$stad}'";

This one where I have simply added an extra concatenation after the variable will also work but in my opinion is significantly less clear about what is happening because we're gluing multiple portions of the string together with multiple quotation marks sitting right next to each other.

<?php

$query = "SELECT stad, modell FROM Biluthyrare a, Bilar b WHERE a.uthyrNr = b.uthyrNr AND stad = '" . $stad . "'";
