Loop through array values - php

Question

I have a small problem:
I need to repeat this
do {
$QUERY = "/member?id=".$counter."&action=refresh";
$URL = $HTTP.$HTTPUSER.":".$HTTPPASS."#".$HTTPSERVER.":".$HTTPPORT.$QUERY;
$xml = file_get_contents($URL);
$data = new SimpleXMLElement($xml);
$test_ip = (string)$data->c1;
$dnsip = explode('<br>', $test_ip);
$ext_ip = strip_tags($dnsip[1]);
if ($ext_ip != "127.0.0.1" && $ext_ip != "localhost") {
$dns = strip_tags($dnsip[0]);
echo "$dns $ext_ip <br>";
}
$counter +=1;
} while (!empty($data));
as many times as there are values inside an array, so i tried to add this
$ports = array('2001','2002','2003');
foreach ($ports as $HTTPPORT) {
echo "$HTTPPORT<br>";
$counter = 1;
do {
$QUERY = "/member?id=".$counter."&action=refresh";
$URL = $HTTP.$HTTPUSER.":".$HTTPPASS."#".$HTTPSERVER.":".$HTTPPORT.$QUERY;
$xml = file_get_contents($URL);
$data = new SimpleXMLElement($xml);
$test_ip = (string)$data->c1;
$dnsip = explode('<br>', $test_ip);
$ext_ip = strip_tags($dnsip[1]);
if ($ext_ip != "127.0.0.1" && $ext_ip != "localhost") {
$dns = strip_tags($dnsip[0]);
echo "$dns $ext_ip <br>";
}
$counter +=1;
} while (!empty($data)); }
The problem is that it executes the script with only first port number (2001), and i can't discover why.
Any Ideas?

You could be getting an exception inside your 'do .. while' loop that is causing bother.
I have added a 'try .. catch' block and some 'echo' statements to ensure it always loops round all the 'ports' now. Changed 'catch' to mark $data as empty then continue.
here is tested code:
<?php
$ports = array('2001','2002','2003');
$counter = 0; // total count of documents
foreach($ports as $HTTPPORT) {
echo $HTTPPORT, ' start of process port loop<br/>';
try { // catch any error -- report it and loop round again
do {
$QUERY = "/member?id=".$counter."&action=refresh";
$URL = ''; // $HTTP.$HTTPUSER.":".$HTTPPASS."#".$HTTPSERVER.":".$HTTPPORT.$QUERY;
try {
$xml = file_get_contents($URL);
$data = new SimpleXMLElement($xml);
}
catch (Exception $e) { // ignore any errors
echo 'SimpleXMLElement : oops :', $e->getMessage(), '<br />';
$data = ''; // mark as empty
}
if (!empty($data)) { // process data
$test_ip = (string)$data->c1;
$dnsip = explode('<br>', $test_ip);
$ext_ip = strip_tags($dnsip[1]);
if ($ext_ip != "127.0.0.1" && $ext_ip != "localhost") {
$dns = strip_tags($dnsip[0]);
echo "$dns $ext_ip <br>";
}
}
$counter +=1;
} while (!empty($data));
} // end of try to get and process a document...
catch (Exception $e) { // catch all errors for now
echo 'Processing List of Ports: oops! :', $e->getMessage(), '<br />';
}
} // end of foreach port
