    <p>Here is the extract of my code that display the excel entries and stores into array .</p> <p>The logic is first, detect which entry is invalid , mark it down, then for other valid entry, check whether it is duplicate, if it is, mark it down.</p> <p>Eventually , scan through the whole sheet again, retrieve all the entries that is not in that two list. (duplicate or invalid)</p> <p>The problems of it are:</p> <p>1) When i display the table, although it can display but it warns me that " datatables warning:Request unknown parameter '0' from the data source for row 0"</p> <p>2) When i store into array, it can only store for the first line of row</p> <p>So , i would like to know are there any mistake in my looping logic? and had i used the PHPEXCEL to read spreadsheet in a correct way? Thank you. <pre><code>$reader = PHPExcel_IOFactory::createReader($readerType); $PHPExcel = $reader-&gt;load($file); $sheet = $PHPExcel-&gt;getSheet(0); $highestRow = $sheet-&gt;getHighestRow(); $highestColumn = PHPExcel_Cell::columnIndexFromString($sheet-&gt;getHighestColumn()); $pattern="/^[\w-]+(?:\.[\w-]+)*@(?:[\w-]+\.)+[a-zA-Z]{2,7}$/"; for ($row = 1; $row &lt;= $highestRow; $row++){ for ($head = 0; $head &lt; $highestColumn; $head++){ $testMail = $sheet-&gt;getCellByColumnAndRow($head, $row)-&gt;getValue(); if (preg_match($pattern,$testMail)) $mailColumn=$head; }} if(!isset($mailColumn)) {die('No email column detected, please check your file and import again.');} $invaild[] = NULL ; $email[] = NULL ; $duplicate[] = NULL ; for ($row = 1; $row &lt;= $highestRow; $row++) { for ($y = 0; $y &lt; $highestColumn; $y++) { $val = $sheet-&gt;getCellByColumnAndRow($y, $row)-&gt;getValue(); if ($y == $mailColumn &amp;&amp; !preg_match($pattern,$val)) {$invaild[]=$row;} elseif ($y == $mailColumn &amp;&amp; in_array($val,$email)) {$duplicate[]=$val; $duplicate[]=$row;} //elseif (!in_array($row,$duplicate) &amp;&amp; !in_array($row,$invaild) ) //{echo $val;} if ($y == $mailColumn) {$email[]=$val; $email=array_unique($email);} } } $invaild=array_unique($invaild); foreach ($invaild as $c) {echo $c;} echo "&lt;br&gt;"; foreach ($duplicate as $d) {echo $d;} ?&gt; &lt;div id="stylized" class="view"&gt; &lt;h1&gt;&lt;?echo $file.'

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.
