So, I only get first value (because class name is without spaces), but I can't get the rest of values
EDIT: I fixed a mistake into PHP code. See again
EDIT2: It's not a duplicate, I tried that solution but It doesn't work
EDIT3: I tried to use advanced_html_dom (it should fix spaces problem), but I don't get anything (also just the only one I was getting)
EDIT4: In the screens below you can see what I'd like to get and what I get right now:

Class-names don't have spaces, don't try to match them
SimpleHtmlDom doesn't support attribute selectors like this. Plus you're tyring to match a class as though it has spaces in the class name. So, instead of this:
$wins = $html->find("td[class=wins col_wins]");
$draws = $html->find("td[class=draws col_draws]");
$losses = $html->find("td[class=losses col_losses]");
Do the following to match td elements which match BOTH of two class-names:
$wins = $html->find("td.wins.col_wins");
$draws = $html->find("td.draws.col_draws");
$losses = $html->find("td.losses.col_losses");
Additionally, that HTML markup doesn't require you to match both classes to get the data, should you could simply do:
$wins = $html->find("td.col_wins");
$draws = $html->find("td.col_draws");
$losses = $html->find("td.col_losses");
Getting repeated selectors (looping through rows).
What you are trying to extract is the an array of data from the rows of a table. More specifically, something that looks like this:
$teams = [
['Arsenal', matches, wins, ...],
['Liverpool', matches, wins, ...],
...
];
This means you'll need to run the same data-extraction against each row of the table. SimpleHtmlDom makes this easy through jQuery-like find methods, which can be called from any matched element.
Complete Solution
This solution actually defines a Team object to load each row's data into. Should make future adjustments much simpler.
The important piece to note here, is that first we loop through every table-row as $row, and collect the team and numbers from $row->find([selector]).
// START team.php
class Team
{
public $name, $matches, $wins, $draws, $losses, $goals;
public function __construct($row)
{
$this->name = $this->parseMatch($row, 'span.team_name_span a');
if (null === $this->name) {
return; // couldn't even match the name, probably not a team row, skip it
}
$this->matches = $this->parseMatch($row, 'td.col_matches_played');
$this->wins = $this->parseMatch($row, 'td.col_wins');
$this->draws = $this->parseMatch($row, 'td.col_draws');
$this->losses = $this->parseMatch($row, 'td.col_losses');
$this->goals = $this->parseMatch($row, 'td.col_goals');
}
private function parseMatch($row, $selector)
{
if (!empty($match = $row->find($selector, 0))) {
return $match->innertext;
}
return null;
}
public function isValid()
{
return null !== $this->name;
}
public function getMatchData() //example
{
return "<br><b>". $this->wins .' : '. $this->matches . "</b>";
}
}
// END team.php
// START DOM parsing block
$teams = [];
foreach($html->find('table.stats-table tr') as $row) {
$team = new Team($row); // load the row into a Team object if possible
// skipp this entry if it couldn't match the row
if ($team->isValid()) {
// what were actually doing here is just the OOP equivalent of:
// $teams[] = ['name' => $row->find('span.team_name_span a',0)->innertext, ...];
$teams[] = $team;
}
}
foreach($teams as $team) {
echo "<h1>".$team->name."</h1>";
echo $team->losses;
echo $team->getMatchData();
}
// END DOM Parsing Block
