    text
    copied!<p>I have an array of arrays like this:</p> <pre><code>[0] { Array[0] { First_Name =&gt; "john" } Array[1] { Last_Name =&gt; "smith" } Array[2] { Job =&gt; "Worker Ant" } } [1] { Array[0] { First_Name =&gt; "jane" } Array[1] { Last_Name =&gt; "smith" } } </code></pre> <p>etc. Let's call it <code>peopleArray</code>;</p> <p>I also have an array of keys such as <code>"First_Name, Last_Name"</code> that would match the keys in the above examples. I'll call it <code>headingArray</code>.</p> <p>I want to echo out <code>peopleArray</code> seperated by commas like this:</p> <p><code>"'john', 'smith', 'Worker Ant'"</code></p> <p><code>'jane','smith',''</code></p> <p>And have the values without keys in the <code>headingArray</code> be just an empty string.</p> <p>I've been trying something like this:</p> <pre><code>for($i=0; $i &lt; count($headingArray); $i++){ foreach($peopleArray as $row){ foreach($row as $data){ if(key($data) == $headingArray[$i]){ echo '"'.current($data).'",'; } } } //die(); echo "\r\n"; } </code></pre> <p>Where I loop through each header and try to match up the values, but it clearly doesn't work. </p> <p>There must be a simpler way of doing this. </p> <p>Can anyone help me out/point me in the right direction? I've been pounding my brain on this for hours.</p> <p>Edit: I've come up with this. It echoes all the values I need, but does some weird thing with skipping the ones that don't exist:</p> <pre><code>foreach($peopleArray as $person) { $prevKey = array(); $numItems = count($person); $i = 0; foreach($person as $heading) { foreach($person as $key =&gt; $value) { if(key($value) == $heading){ echo '"'.str_replace(',',' ',current($value)).'",'; $prevKey[] = key($value); break; } else if(in_array(key($value), $prevKey)) { } else { echo '"",'; } } //die(var_dump($prevKey)); $i++; } echo "\r\n"; } </code></pre> <p>I need it to return a blank string if it doesn't exist.</p>
