How can I fix this error?

I'm using file_get_contents and file_put_contents in the context of an app that I'm building. I've been able to successfully get the content and write to a new html file, but when I go and try to retrieve the content from the page using loadHTML(), I'm getting an error and I'm not sure where it's coming from.

Here's my code:

<?php
libxml_use_internal_errors(true);
if (file_get_contents('https://ncws.vh.eng.vzwcorp.com:8080/reports/delvane/volte_7_day.html')) {
$datafile14 = file_get_contents('https://ncws.vh.eng.vzwcorp.com:8080/reports/delvane/volte_7_day.html');
echo "Uploading Filename: https://ncws.vh.eng.vzwcorp.com:8080/reports/delvane/volte_7_day.html\n";
file_put_contents('raw_html/crystal.html',$datafile14);
//chmod("raw_html/crystal.html",0777);
echo "data has been uploaded!";
}
$html = file_get_contents('raw_html/crystal.html');


    /*** a new dom object ***/ 
    $dom = new domDocument; 

    /*** load the html into the object ***/ 
    $dom->loadHTML($html); 
	if(!$dom) 
	{
	echo "you've got a problem...!";
	}

    /*** discard white space ***/ 
    $dom->preserveWhiteSpace = false; 

    /*** the table by its tag name ***/ 
    $tables = $dom->getElementsByTagName('table'); 

    /*** get all rows from the table ***/ 
    $rows = $tables->item(0)->getElementsByTagName('tr'); 

    /*** loop over the table rows ***/ 
    foreach ($rows as $row) { 
        /*** get each column by tag name ***/ 
$cols = $row->getElementsByTagName('td'); 

$enddate = $cols->item[0]->nodeValue;
$num_days = $cols->item[1]->nodeValue;
$area = $cols->item[2]->nodeValue;
$mmepool = $cols->item[3]->nodeValue;
$region = $cols->item[4]->nodeValue;
$vendor = $cols->item[5]->nodeValue;

$volte_qci1_setup_attempts = $cols->item[11]->nodeValue;

$rrc_setup_attempts = $cols->item[19]->nodeValue;
$rrc_setup_failures = $cols->item[20]->nodeValue;
$volte_qci1_drop_pcnt = $cols->item[21]->nodeValue;
$volte_qci1_drops = $cols->item[22]->nodeValue;
$volte_qci1_established_calls = $cols->item[23]->nodeValue;

$volte_avg_mos = $cols->item[27]->nodeValue;
$volte_mos_numerator = $cols->item[28]->nodeValue;
$volte_mos_denominator = $cols->item[19]->nodeValue;
$volte_pdcp_dl_volume_mb = $cols->item[30]->nodeValue;
$volte_dl_volume_pcnt = $cols->item[31]->nodeValue;
$lte_pdcp_dl_volume_mb = $cols->item[32]->nodeValue;
$x7x24_volte_pdcp_dl_volume_mb = $cols->item[33]->nodeValue;
$x7x24_volte_dl_volume_pcnt = $cols->item[34]->nodeValue;
$x7x24_lte_pdcp_dl_volume_mb = $cols->item[35]->nodeValue;
$volte_pdcp_ul_volume_mb = $cols->item[36]->nodeValue;
$volte_ul_volume_pcnt = $cols->item[37]->nodeValue;
$lte_pdcp_ul_volume_mb = $cols->item[38]->nodeValue;
$x7x24_days = $cols->item[39]->nodeValue;
}
echo $x7x24_days;
?>

The error I'm getting is: "Notice: Undefined property: DOMNodeList::$item in /opt/lampp/htdocs/crystal/test.php on line 37."

After that I get the expected parade of errors as my code tries to retrieve data from what is perceived as a "non-object."

What am I missing?
