Combine 2 separate foreach loops

Question

so far ive managed to scrape 2 elements from an external site on to my test page: http://mt-cloud.co.uk/nhs/

(Please do a test search on the page to view results)

$ch = curl_init('http://www.nhs.uk/service-search/GP/m410ux/Results/4/-2.35167407989502/53.4519462585449/4/0?distance=25');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
$output = curl_exec($ch);
curl_close($ch);

$document = new DOMDocument;
libxml_use_internal_errors(true);
$document->loadHTML($output);
$document->encoding = 'utf-8';
$xpath = new DOMXPath($document);
$pnames = $xpath->query("//th[@class='fctitle']");
$addresses = $xpath->query("//td[@class='fcdetails fc-first']");

I have 2 foreach loops:

foreach ($pnames as $pname) {
$result1 = $document->saveHTML($pname);
}


foreach ($addresses as $address) {
$result2 = $document->saveHTML($address);
}

$result1 = Name of a GP Practice $result2 = Address of GP Practice

As you see on the test page my result 1 and 2 are seperated..how do i get the them so i have Practice name and Practice Address together?

UPDATE (@Tri)

for($i = 0; $i < count($pnames); $i++){
$name= $document->saveHTML($pnames[$i]);
$name=str_replace ('<a href="/Services/', '<a href="http://www.nhs.uk/Services/', $name);
$address = $document->saveHTML($addresses[$i]);

echo $name.'<br>'.$address;
}

Only returns one result rather than all

You first code was OK, you just need to store your names and addresses in an 2 dimensional array and then loop through your array.

This part of the code is exactly same as yours:

$ch = curl_init('http://www.nhs.uk/service-search/GP/m410ux/Results/4/-2.35167407989502/53.4519462585449/4/0?distance=25');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
$output = curl_exec($ch);
curl_close($ch);

$document = new DOMDocument;
libxml_use_internal_errors(true);
$document->loadHTML($output);
$document->encoding = 'utf-8';
$xpath = new DOMXPath($document);
$pnames = $xpath->query("//th[@class='fctitle']");
$addresses = $xpath->query("//td[@class='fcdetails fc-first']");

Now we will create an array:

$results = array();

Then use your loops and store names and addresses as pairs in same indexs of array:

$iCnt = 0;
foreach ($pnames as $pname){
    $results[$iCnt]['name'] = $document->saveHTML($pname);
    $iCnt++;
}

$iCnt = 0;
foreach ($addresses as $address){
    $results[$iCnt]['address'] = $document->saveHTML($address);
    $iCnt++;
}

Now we have an array with pairs of names and addresses and if we loop through it, we can see them together:

for($iCnt = 0, $cnt = count($results); $iCnt < $cnt; $iCnt++){
    echo 'Name: '.$results[$iCnt]['name'].'<br>';
    echo 'Address: '.$results[$iCnt]['address'].'<br>';
}

That's all. The complete code will look like this:

<?php
$ch = curl_init('http://www.nhs.uk/service-search/GP/m410ux/Results/4/-2.35167407989502/53.4519462585449/4/0?distance=25');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
$output = curl_exec($ch);
curl_close($ch);

$document = new DOMDocument;
libxml_use_internal_errors(true);
$document->loadHTML($output);
$document->encoding = 'utf-8';
$xpath = new DOMXPath($document);
$pnames = $xpath->query("//th[@class='fctitle']");
$addresses = $xpath->query("//td[@class='fcdetails fc-first']");

$results = array();

$iCnt = 0;
foreach ($pnames as $pname){
    $results[$iCnt]['name'] = $document->saveHTML($pname);
    $iCnt++;
}

$iCnt = 0;
foreach ($addresses as $address){
    $results[$iCnt]['address'] = $document->saveHTML($address);
    $iCnt++;
}

for($iCnt = 0, $cnt = count($results); $iCnt < $cnt; $iCnt++){
    echo 'Name: '.$results[$iCnt]['name'].'<br>';
    echo 'Address: '.$results[$iCnt]['address'].'<br>';
}
?>

Answer 2

So just do not use foreach:

for($i = 0; $i < count($pnames); $i++){
    $name= $document->saveHTML($pnames[$i]);
   $address = $document->saveHTML($addresses[$i]);
   //do something with your result
}

Note: you must make sure that length of addresses equal to pnames
