how to skip InnerText empy in a If statment using php - php

Question

I am trying to skip when InnerText is empty but it put a default value.
This is my code:
if (strip_tags($result[$c]->innertext) == '') {
$c++;
continue;
}
This is the output:
Thanks
EDIT2: I did the var_dump
var_dump($result[$c]->innertext)
and I got this:
how can I fix it please?
EDIT3: This is my code; I extract in this way the names of the teams and the results, but the last one not works in the best way when We have postponed matches
<?php
include('../simple_html_dom.php');
function getHTML($url,$timeout)
{
$ch = curl_init($url); // initialize curl with given url
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]); // set useragent
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // write the response to a variable
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects if any
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); // max. seconds to execute
curl_setopt($ch, CURLOPT_FAILONERROR, 1); // stop when it encounters an error
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
return #curl_exec($ch);
}
$response=getHTML("https://www.betexplorer.com/soccer/japan/j3-league/results/",10);
$html = str_get_html($response);
$titles = $html->find("a[class=in-match]"); // name match
$result = $html->find("td[class=h-text-center]/a"); // result match
$c=0; $b=0; $o=0; $z=0; $h=0; // set counters
foreach ($titles as $match) { //get all data
$match_status = $result[$h++];
if (strip_tags($result[$c]->innertext) == 'POSTP.') { //bypass postponed match but it doesn't work anymore
$c++;
continue;
}
list($num1, $num2) = explode(':', $result[$c++]->innertext); // <- explode
$num1 = intval($num1);
$num2 = intval($num2);
$num3 = ($num1 + $num2);
$risultato = ($num1 . '-' . $num2);
list($home, $away) = explode(' - ', $titles[$z++]->innertext); // <- explode
$home = strip_tags($home);
$away = strip_tags($away);
$matchunit = $home . ' - ' . $away;
echo "<tr><td class='rtitle'>".
"<td> ".$matchunit. "</td> / " . // name match
"<td class='first-cell'>" . $risultato . "</td> " .
"</td></tr><br/>";
} //close foreach
?>

By browsing the content of the website you will always be dependent on the changes made in the future.
However, I will use PHP's native libxml DOM extension.
By doing the following:
<?php
function getHTML($url,$timeout)
{
$ch = curl_init($url); // initialize curl with given url
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]); // set useragent
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // write the response to a variable
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects if any
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); // max. seconds to execute
curl_setopt($ch, CURLOPT_FAILONERROR, 1); // stop when it encounters an error
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
return #curl_exec($ch);
}
$response=getHTML("https://www.betexplorer.com/soccer/japan/j3-league/results/",10);
// "Create" the new DOM document
$doc = new DomDocument();
// Load HTML from a string, and disable xml error handling
$doc->loadHTML($response, LIBXML_NOERROR);
// Creates a new DOMXPath object
$xpath = new DomXpath($doc);
// Evaluates the given XPath expression and get all tr's without first line from table main
$row = $xpath->query('//table[#class="table-main js-tablebanner-t js-tablebanner-ntb"]/tr[position()>1]');
echo '<table>';
// Parse the values in row
foreach ($row as $tr) {
// Only get 2 first td's
$col = $xpath->query('td[position()<3]', $tr);
// Do not show POSTP and Round values
if (!str_contains($tr->nodeValue, 'POSTP') && !str_contains($tr->nodeValue, 'Round')) {
echo '<tr><td>'.$col->item(0)->nodeValue.'</td><td>'.$col->item(1)->nodeValue.'</td></tr>';
}
}
echo '</table>';
You obtain:
<tr><td>Nagano - Tegevajaro Miyazaki</td><td>3:2</td></tr>
<tr><td>YSCC - Toyama</td><td>1:2</td></tr>
