    <p><strong>Edit:</strong> Okay, I've re-read your question and I think I get what you're talking about now:<br> you want something like this to work:</p> <pre><code>// myInclude.php $x = "abc"; // ----------------------- // myRegularFile.php function doInclude() { include 'myInclude.php'; } $x = "A default value"; doInclude(); echo $x; // should be "abc", but actually prints "A default value" </code></pre> <p>If you are only changing a couple of variables, and you know ahead of time which variables are going to be defined in the include, declare them as <code>global</code> in the <code>doInclude()</code> function.</p> <p>Alternatively, if each of your includes could define any number of variables, you could put them all into one array:</p> <pre><code>// myInclude.php $includedVars['x'] = "abc"; $includedVars['y'] = "def"; // ------------------ // myRegularFile.php function doInclude() { global $includedVars; include 'myInclude.php'; // perhaps filter out any "unexpected" variables here if you want } doInclude(); extract($includedVars); echo $x; // "abc" echo $y; // "def" </code></pre> <hr> <p><em>original answer:</em></p> <p>this sort of thing is known as "closures" and are being introduced in PHP 5.3</p> <p><a href="http://steike.com/code/php-closures/" rel="nofollow noreferrer">http://steike.com/code/php-closures/</a></p> <blockquote> <p>Would it be better to use extract($_GLOBALS); inside my function call instead?</p> </blockquote> <p>dear lord, no. if you want to access a global variable from inside a function, just use the <code>global</code> keyword. eg:</p> <pre><code>$x = "foo"; function wrong() { echo $x; } function right() { global $x; echo $x; } wrong(); // undefined variable $x right(); // "foo" </code></pre>

    1. COThis is exactly the issue I've run into. I'm trying to develop a plugin for a script, but unfortunately that script does some odd things with globals. It's a pain to track all of the various globals that I need and declare them in the "doInclude" function. Oh well... I thought $GLOBALS would work, but that doesn't work because of the order of functions and includes. Such is the life of a plugin developer I guess.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
