White Space in Key of Associative Array PHP - php

Question

I'm parsing out an HTML table and building an array based on the row values. My problem is the associative keys that are returned have a bit of white space at the end of them giving me results like this:
Array ( [Count ] => 6 [Class ] => 30c [Description] => Conformation Model (Combined 30,57) )
So a line like this:
echo $myArray['Count'];
or
echo $myArray['Count '];
Gives me a blank result.
for now I've got a pretty hacky work around going...
foreach($myArray as $row){
$count = 0;
foreach($row as $info){
if($count == 0){
echo 'Count:' . $info;
echo '<br>';
}
if($count == 1){
echo ' Class:' . $info;
echo '<br>';
}
if($count == 2){
echo ' Description:' . $info;
echo '<br>';
}
$count++;
}
}
The function I'm using to parse the table I found here:
function parseTable($html)
{
// Find the table
preg_match("/<table.*?>.*?<\/[\s]*table>/s", $html, $table_html);
// Get title for each row
preg_match_all("/<th.*?>(.*?)<\/[\s]*th>/", $table_html[0], $matches);
$row_headers = $matches[1];
// Iterate each row
preg_match_all("/<tr.*?>(.*?)<\/[\s]*tr>/s", $table_html[0], $matches);
$table = array();
foreach($matches[1] as $row_html)
{
preg_match_all("/<td.*?>(.*?)<\/[\s]*td>/", $row_html, $td_matches);
$row = array();
for($i=0; $i<count($td_matches[1]); $i++)
{
$td = strip_tags(html_entity_decode($td_matches[1][$i]));
$row[$row_headers[$i]] = $td;
}
if(count($row) > 0)
$table[] = $row;
}
return $table;
}
I'm assuming I can eliminate the white space by updating with the correct regex expression, but, of course I avoid regex like the plague. Any ideas? Thanks in advance.

Answer 1

You can use trim to remove leading and trailing whitespace characters:
$row[trim($row_headers[$i])] = $td;
But don’t use regular expressions for parsing the HTML document; use a proper HTML parser like the Simple HTML DOM Parser or the one of DOMDocument instead.

Answer 2

An easy solution would be to change
$row[$row_headers[$i]] = $td;
to:
$row[trim($row_headers[$i])] = $td;
