    <p>The simplest solution I can think of:</p> <pre><code>// The filename to write to $csvFile = 'theCSVfile.csv'; $csvRows = array(); foreach ($collection as $product_all) { $sku = $product_all['sku']; $product_id = Mage::getModel('catalog/product')-&gt;getIdBySku($sku); $product = Mage::getModel('catalog/product'); $product -&gt;load($product_id); // Replacing quotation marks with CSV escaped ones $name = str_replace( '"' , '""' , $product['name'] ); $csvRows[] = "{$sku},\"{$name}\""; } file_put_contents( $csvFile , implode( "\n" , $csvRows ) ); </code></pre> <p>Bear in mind that this may produce invalid CSV syntax if the <code>$name</code> variable contains commas or other unusual characters.</p> <p>As noted by <strong>Bogdan</strong>, this may be memory intensive, as it involves holding all of the rows in RAM before performing a single write to the file. If that is a concern, or you are dealing with a very large number of rows, the following code batches the writes into smaller chunks.</p> <pre><code>// The filename to write to $csvFile = 'theCSVfile.csv'; // Rows per chunk $csvChunk = 1000; // Initialise the Array $csvRows = array(); // Variable to check if first write performed $firstWriteDone = false; function writeChunk(){ global $csvFile, $csvRows, $csvChunk, $firstWriteDone; if( count( $csvRows )==$csvChunk ){ // Chunk Limit Reached - Write to disk file_put_contents( $csvFile , ( !$firstWriteDone ? "\n" : '' ) . implode( "\n" , $csvRows ) , ( !$firstWriteDone ? FILE_APPEND : 0 ) ); // Set the First Write Done flag $firstWriteDone = true; // Reset the Array $csvRows = array(); } } foreach ($collection as $product_all) { $sku = $product_all['sku']; $product_id = Mage::getModel('catalog/product')-&gt;getIdBySku($sku); $product = Mage::getModel('catalog/product'); $product -&gt;load($product_id); // Replacing quotation marks with CSV escaped ones $name = str_replace( '"' , '""' , $product['name'] ); $csvRows[] = "{$sku},\"{$name}\""; if( count( $csvRows )==$csvChunk ){ // Chunk Limit Reached - Write to disk writeChunk(); } } if( count( $csvRows ) ){ // Write the Last Chunk, even if not at the limit writeChunk(); } </code></pre>

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.
