  1. POVariable variables to call programmatically-created arrays
    text
    copied!<p>I am creating a series of arrays from template tags in a content management system, and outputting the titles of these arrays as arrays labeled with variables:</p> <pre><code>&lt;Loop&gt; $&lt;GeneratedArrayName1&gt; = array( "foo" =&gt; "bar" ); $&lt;GeneratedArrayName2&gt; = array( "foo" =&gt; "bar" ); &lt;/Loop&gt; </code></pre> <p>I'm also generating another array of possible GeneratedArrayNames and sorting it by count. I'm looping through this array to get the GeneratedArrayNames so I can selectively show them. After I sort, I want to pull and display only a few of the many arrays I have with GeneratedArrayNames. I'm doing this by positioning the pointer at the top of the master array and getting the name:</p> <pre><code>reset($ArrayNames); $firstArray = current($ArrayNames); //outputs GeneratedArrayName1 </code></pre> <p>Then I went to pull the GeneratedArrayName by getting the Variable variable, which gives me an error:</p> <pre><code>print_r(${$firstArray}); // outputs Undefined variable: GeneratedArrayName1 </code></pre> <p>But when I hardcode, I get the correct data: </p> <pre><code>print_r($GeneratedArrayName1); // outputs the array </code></pre> <p>Where am I going wrong?</p> <p><em>EDIT</em></p> <p>I am getting <code>$firstArray</code> by this loop:</p> <pre><code>$count = 0; foreach($ArrayNames as $ArrayCount =&gt; $ArrayName) { $count++; echo "$ArrayName" . ' - ' . "$ArrayCount" . '&lt;br&gt;'; if ($count &gt;= 3) { break; } } //from here I proceed to reset($ArrayNames) </code></pre>
