Update page after each cURL Request - php

Question

I have the following code:
$fiz = $_GET['file'];
$file = file_get_contents($fiz);
$trim = trim($file);
$tw = explode("\n", $trim);
$browser = 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1468.0 Safari/537.36';
foreach($tw as $twi){
$url = 'https://twitter.com/users/username_available?username='.$twi;
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_USERAGENT, '$browser');
curl_setopt($ch, CURLOPT_TIMEOUT, 8);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
$json = json_decode($result, true);
if($json['valid'] == 1){
echo "Twitter ".$twi." is available! <br />";
$fh = fopen('available.txt', 'a') or die("can't open file");
fwrite($fh, $twi."\n");
} else {
echo "Twitter ".$twi." is taken! <br />";
}
}
And what it does is that it takes list that would look something like:
apple
dog
cat
and so on, and it checks it with Twitter to check if the name is taken or not.
What I want to know is that if it's in any way possible to make the request show up after each check in instead of showing up all at once?

You need to use Ajax calls, If you are familiar with JavaScript or Jquery you can easily do this.
Instead of checking all names at once , use an Ajax function to send one name at a time to the server side PHP code.
Say you send "Cat" first , the page is processed and returns the result using Ajax. Now you can display the result on page.
send "dog" get the response---> display it and so on.

Hope this helps, I use Jquery here ...
JavaScript
<script>
var keyArray = ('cat','dog','mouse','rat');
function checkUserName(name, keyArray, position){
$("#result").load("namecheck.php", {uesername: name, function(){ // Results are displayed on 'result' element
fetchNext(keyArray, position);
});}
}
function fetchNext(keyArray, position){
position++; // get next name in the array
if(position < keyArray.lenght){ // not exceeding the aray count
checkUserName(keyArray[position], keyArray, position) // make ajax call to check user name
}
}
function startProcess(){
var keyArray = ('cat','dog','mouse','rat');
var position = 0; // get the first element from the array
fetchNext(keyArray, position);
}
</script>
HTML
<div id="result"></div>
<button onclick="startProcess()"> Start Process </button>
PHP
<?
$twi = $_GET['username'];
$browser = 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1468.0 Safari/537.36';
$url = 'https://twitter.com/users/username_available?username='.$twi;
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_USERAGENT, '$browser');
curl_setopt($ch, CURLOPT_TIMEOUT, 8);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
$json = json_decode($result, true);
if($json['valid'] == 1){
echo "Twitter ".$twi." is available! <br />";
$fh = fopen('available.txt', 'a') or die("can't open file");
fwrite($fh, $twi."\n");
}else{
echo "Twitter ".$twi." is taken! <br />";
} ?>
