<p>Tuncerd: </p> <hr /> <div><br /> =Debugging=<br /> <br /> Working with a framework can sometimes be hard to debug. In Yii we have some tools at our disposal to help debug the application. The very first thing to do is modify '''application/config/config-defaults.php''' and to set [[Optional_settings#Development_and_debugging|debug = 2]] at the end. Now we get more errors presented and we can use a trace function to see what a variable's content is at any time during program execution.<br /> <br /> If you want to see what queries are sent to the database, you can also enable debugsql by setting it to 1.<br /> <br /> To do a dump of a variable you can use the following syntax:<br /> <br /> &lt;syntaxhighlight lang=&quot;php&quot; enclose=&quot;div&quot;&gt;$variable = $this-&gt;someMethod();  // What would this return?<br /> <br /> Yii&lt;center&gt;trace(CVarDumper&lt;/center&gt;dumpAsString($variable), 'vardump');&lt;/syntaxhighlight&gt;<br /> <br /> We make use of the &lt;nowiki&gt;Yii&lt;center&gt;trace()&lt;/nowiki&gt; method, and pass it the result of the static call to &lt;nowiki&gt;CVarDumper&lt;/center&gt;dumpAsString()&lt;/nowiki&gt;. What it does is similar to var_dump but it allows a little more control if you need it. The second parameter 'vardump' makes sure our messages gets logged. All this is a lot of typing and since programmers are lazy, we created a global function to save you some trouble. Instead of the lines above you can also use:<br /> <br /> &lt;syntaxhighlight lang=&quot;php&quot; enclose=&quot;div&quot;&gt;traceVar($variable);&lt;/syntaxhighlight&gt;<br /> <br /> As a bonus you will also get the file and line that called the traceVar function to assist in debugging.</div>
