$ip=1;US;USA;United States

here i need only iso3 code of that country how seprate that variable to get output like this.

There should be a string split function. I think in PHP it's called explode — Brian, Dec 07 '18 at 13:01

$ipArr = explode(';',$ip);

if (is_array($ipArr)) {
    $iso3=$ipArr[2];
}
else {
    $iso3='same default value or error msg';
}

Your if statement is obsolete, you can simplify it as: `$iso3= $ipArr[2] ?? "default value or error msg"` see: http://php.net/manual/en/migration70.new-features.php#migration70.new-features.null-coalesce-op – Sven Hakvoort Dec 07 '18 at 13:14

First you'll want to use explode with the ';' as the delimiter. This is going to cut up the string at each ';' that it contains.

Example:

$ip = "1;US;USA;United States";

$ipValues = explode(';', $ip);

The result is going to be:

  [
      0 => '1',
      1 => 'US',
      2 => 'USA',
      3 => 'United States',
  ]

Then you simply assign the ISO code to your variable like so:

$iso3 = $ipValues[2];
