使用php获取HTML节点值

Question

I'am parsing an HTML file and getting values of the 'td' tags, what I want is to get are the char values of each string. Here is my code:

$content = "";

$data = file_get_contents('https://www.oncf.ma/fr/Horaires? from%5B00229%5D%5B0093%5D=RABAT+AGDAL&to%5B00206%5D%5B0093%5D=CASA+PORT&datedep=27%2F05%2F2018+01%3A00&dateret=&is-ar=0');

$doc = new DOMDocument();
@$doc->loadHTML($data);
$items = $doc->getElementsByTagName('td');
$i=0;
if(count($items)>0)  
{
    foreach ($items as $heure)
    {    
        $content .= $heure->NodeValue; 
    }   
}
else
{
    $content = $doc->saveHTML();
}
echo $content;

I want to get the value of every char of the string: $heure->NodeValue.

Answer 1

Its typo here please replace

$heure->NodeValue

to

$heure->nodeValue

Edited

Please add a line before last echo

$content = preg_replace('/[0-9]+/', '', $content);
echo $content;
