在PHP中将字符串拆分为2个变量

Question

I have a string with the following format: city (Country) and I would like to separate the city and the country and store the values in 2 different variables.

I tried the following and it is working to store the city but not for the country.

<?php

$citysearch = "Madrid (Spain)";
echo $citysearch;

$citylen = strlen( $citysearch );
for( $i = 0; $i <= $citylen; $i++ )
{
  $char = substr( $citysearch, $i, 1 );
  if ($char <> "(")
  {
    echo $city. "<br>"; 
    $city = $city .$char;
    if ($char == " ")
    {
      break;
    } 
  }
  if ($char <> ")")
  {
    echo $country. "<br>"; 
    $country = $country .$char;
    if ($char == ")")
    {
      break;
    } 
  }
}

echo "This is the city:" .$city;
echo "This is the country:" . $country;;

?>

Any help would be highly appreciated.

You can use a simple regex to solve this:

preg_match('/^(\w*)\s\((\w*)\)$/', $citysearch, $matches);
var_dump($matches);
echo "city: ".$matches[1]."
";
echo "country: ".$matches[2]."
";

Update:
Or without regex:

$citysearch = 'Madrid (Spain)';
$pos = strpos($citysearch, ' (');
$city = substr($citysearch, 0, $pos);
$country = substr($citysearch, $pos + 2, -1);
