    copied!<h2>Note: I'm not interested in how I can parse anything into HTML. I already know that. In this scenario I'm extracting the HTML from a site, and I try to find the best way to make an array of all the different keys and values multiple selects can produce.</h2> <p>I'm trying to convert pages with <code>&lt;select&gt;&lt;option&gt;</code> where I fetch <code>name=""</code> and <code>value=""</code> in order to get the value. This data will be transferred to an array:</p> <pre><code>&lt;select name="example"&gt; &lt;option value="1"&gt;1&lt;/option&gt; &lt;option value="2"&gt;2&lt;/option&gt; &lt;option value="3"&gt;3&lt;/option&gt; &lt;/select&gt; </code></pre> <p>would give:</p> <pre><code>array(array('example' =&gt; 1), array('example' =&gt; 2), array('example' =&gt; 3)) </code></pre> <p>However, in my case there can be multiple <code>&lt;select&gt;</code>, so I need some logic to take these values and create all possible combinations in that array. I wish to be getting these as an array with 4 arrays with 2 same keys but different values:</p> <pre><code>&lt;select name="example"&gt; &lt;option value="1"&gt;1&lt;/option&gt; &lt;option value="2"&gt;2&lt;/option&gt; &lt;/select&gt; &lt;select name="second"&gt; &lt;option value="1"&gt;1&lt;/option&gt; &lt;option value="2"&gt;2&lt;/option&gt; &lt;/select&gt; </code></pre> <p>Would become:</p> <pre><code>array(array('example' =&gt; 1, 'second' =&gt; 1), array('example' =&gt; 1, 'second' =&gt; 2), array('example' =&gt; 2, 'second' =&gt; 1), array('example' =&gt; 2, 'second' =&gt; 2)) </code></pre> <p>What method in php would be more ideal to create these arrays? Only way I can think of are several loops in each other. I want this solution to be scalable and work with as many <code>&lt;select&gt;</code> as possible.</p>
