Question

I need get multiple values from span tags using php, for example :

   <div>
    <span class='name'>name value</span>
    <span class='city'>city name</span>
    <span class='street'>street name</span>
    <span class='phone'>[phone]</span>
    </div>
  <div>
   <span class='name'>name value 2</span>
   <span class='city'>city name 2</span>
   <span class='street'>street name 2</span>
   <span class='phone'>[phone]</span>
  </div> 

I have to get span values using span class, i try this code to get the value, and it’s working put for just 1 value such as “name” :

<?
$html = "<div>
         <span class='name'>name value</span>
         <span class='city'>city name</span>
         <span class='street'>street name</span>
         <span class='phone'>[phone]</span>
         </div>
         <div>
         <span class='name'>name value 2</span>
         <span class='city'>city name 2</span>
         <span class='street'>street name 2</span>
         <span class='phone'>[phone]</span>
         </div>";
$dom = new DOMDocument();
@$dom->loadHTML($html);
$dom_xpath = new DOMXPath($dom);

$entries = $dom_xpath->evaluate("//span[@class='name']");
foreach ($entries as $entry) {
   echo  $entry->nodeValue."<br />";
}
?>

Is there anyone to help me to retouch the code so i can get all values

Thanks

Try changing

......
$dom = new DOMDocument();
@$dom->loadHTML($html);

foreach($dom->getElementsByTagName('span') as $span){
  echo $span->nodeValue . '<br>';
  //echo $span->getAttribute('class');
}

Base on the above format you may want to try this (assuming that the className will never change and always present)

......
$dom = new DOMDocument();
@$dom->loadHTML($html);

$result = array();
foreach ($dom->getElementsByTagName('div') as $div){
    $temp = array();
    foreach($div->getElementsByTagName('span') as $span){
        $temp[$span->getAttribute('class')] = $span->nodeValue; 
    }

    // db insert here
    // You may want to do some error check before inserting the data by making sure the array key exist 
    // need to escape data (SQL_injection)
    //mysql_query("INSERT INTO db (`name`,`city`,`street`,`phone`) VALUES('{$temp['name']}','{$temp['city']}','{$temp['street']}','{$temp['phone']}')");

    $result[] = $temp;

}

print_r($result);

You need to escape you values before inserting them into db (sql injection) and a more efficient want of doing bulk insert —

OR

 $entries = $dom_xpath->evaluate("//span[@class='name']")

to

 $entries = $dom_xpath->evaluate("//span")
