PHP: Return multiple results by if else statement

Question

What I want to achieve is to check multiple domain availability.

Here is my code:

<?php
//$domain = 'example.com';
$domain = array('example.com', 'foo.com');

if ( checkdnsrr(in_array($domain), 'ANY') ) {
  $echo_checkdnsrr = in_array($domain) . " DNS Record found (checkdnsrr)" . "<br />" . PHP_EOL;
}
else {
  $echo_checkdnsrr = in_array($domain) . " NO DNS Record found (checkdnsrr)" . "<br />" . PHP_EOL;
}

if ( gethostbyname(in_array($domain)) != in_array($domain) ) {
  $echo_gethostbyname = in_array($domain) . " DNS Record found (gethostbyname)" . "<br />" . PHP_EOL;
}
else {
  $echo_gethostbyname = in_array($domain) . " NO DNS Record found (gethostbyname)" . "<br />" . PHP_EOL;
}

$separator = "-------------------------------------------" . "<br />" . PHP_EOL;

print_r($echo_checkdnsrr);
print_r($echo_gethostbyname);
echo $separator;
?>

What I want to achieve:

example.com DNS Record found (checkdnsrr)
example.com DNS Record found (gethostbyname)
-------------------------------------------
foo.com DNS Record found (checkdnsrr)
foo.com DNS Record found (gethostbyname)
-------------------------------------------

Thank You for your help!

Thank You to @fluinc, here is my final code:

$domains = array('example.com', 'foo.com');

foreach ($domains as $domain) {
    if (checkdnsrr($domain, 'ANY') || gethostbyname($domain) != $domain) {
        echo "TAKEN " . $domain . "<br />" . PHP_EOL;
    } else {
        echo "AVAILABLE " . $domain . "<br />" . PHP_EOL;
    }
}

This is what it's returns:

TAKEN example.com
TAKEN foo.com

Later on it's super easy to import in excel, choose space as separator and find out the available domains with a query.

I would start with a foreach() to loop through the domains in the array. — Fluinc

@BenPearlKahan It just returns "array DNS record found (checkdnsrr)\r\narray DNS record not found (gethostbyname)" I think it's messing up multiple results into one query. Somehow needs to echoing multiple results into multiple outputs. — Lanti

Use a foreach to loop through the domains, Your use of in_array is wrong and not needed.

$domains = array('example.com', 'foo.com');

foreach ($domains as $domain) {
    if (checkdnsrr($domain, 'ANY')) {
        echo $domain . " DNS Record found (checkdnsrr)<br />". PHP_EOL;
    } else {
        echo $domain . " NO DNS Record found (checkdnsrr)<br />". PHP_EOL;
    }

    if (gethostbyname($domain) != $domain) {
        echo $domain . " DNS Record found (gethostbyname)<br />". PHP_EOL;
    } else {
        echo $domain . " NO DNS Record found (gethostbyname)<br />". PHP_EOL;
    }
    echo "-------------------------------------------<br />". PHP_EOL;
}

Updated as per comment

$domains = array('example.com', 'foo.com');

foreach ($domains as $domain) {
    if (checkdnsrr($domain, 'ANY') || gethostbyname($domain) != $domain) {
        echo $domain . " TAKEN<br />". PHP_EOL;
    } else {
        echo $domain . " AVAILABLE<br />". PHP_EOL;
    }

    echo "-------------------------------------------<br />". PHP_EOL;
}

Thank You! Works like a charm! Is it possible only return something if one of the checkdnsrr or gethostbyname is true? Because this way only one line enough for one domain. So only will be enough $domain . 'AVAILABLE' and $domain . 'TAKEN'?

Try using foreach() and echo out each result as it is processed:

$domains = array('example.com', 'foo.com');

foreach($domains as $domain){
    if(checkdnsrr(in_array($domain), "ANY")){
        echo in_array($domain) . " DNS Record found (checkdnsrr)" . "<br />" . PHP_EOL;
    } else {
        echo in_array($domain) . " NO DNS Record found (checkdnsrr)" . "<br />" . PHP_EOL;
    }

    if(gethostbyname(in_array($domain)) != in_array($domain)) {
        echo in_array($domain) . " DNS Record found (gethostbyname)" . "<br />" . PHP_EOL;
    } else {
        echo in_array($domain) . " NO DNS Record found (gethostbyname)" . "<br />" . PHP_EOL;
    }

    echo "-------------------------------------------" . "<br />" . PHP_EOL;
}

Shorter:

$domains = array('example.com', 'foo.com');

foreach($domains as $domain){
    echo in_array($domain).(checkdnsrr(in_array($domain), "ANY") ? "NO " : "")."DNS Record found (checkdnsrr)" . "<br />" . PHP_EOL;
    echo in_array($domain).(gethostbyname(in_array($domain))!= in_array($domain) ? "NO " : "")."Record found (gethostbyname)" . "<br />" . PHP_EOL;
    echo "-------------------------------------------" . "<br />" . PHP_EOL;
}
