UK Post codes to latitude - longitude

Hi folks,

Apart from the conventional Google API for retrieving the latitude and longitude of any location by:

http://maps.googleapis.com/maps/api/geocode/json?address=<Address>&sensor=false

The above works quit beautifully for me. But the only problem was with its daily query limit. That is, you cannot make more than one particular number of calls to the above API from a single IP address.

So I started researching on other available API's for generating lat/lon from a given post code/city/town. Since my requirement was just for UK, so the following API URL came in very handy to me:

Remove special characters - PHP

Hi,

I know there are a million ways to remove special characters but this is one of the better solutions which I came across over the internet. Here is the PHP function:

function just_clean($string)
{
// Replace other special chars
$specialCharacters = array(
‘#’ => ”,
‘$’ => ”,
‘%’ => ”,
‘&’ => ”,
‘@’ => ”,
‘.’ => ”,
‘€’ => ”,
‘+’ => ”,
‘=’ => ”,
‘§’ => ”,
‘\\’ => ”,
‘/’ => ”,
);
while (list($character, $replacement) = each($specialCharacters)) {
$string = str_replace($character, '-' . $replacement . '-', $string);
}
$string = strtr($string,
"ÀÁÂÃÄÅ? áâãäåÒÓÔÕÖØòóôõöøÈÉÊËèéêëÇçÌÍÎÏìíîïÙÚÛÜùúûüÿÑñ",
"AAAAAAaaaaaaOOOOOOooooooEEEEeeeeCcIIIIiiiiUUUUuuuuyNn"
);
// Remove all remaining other unknown characters
$string = preg_replace('/[^a-zA-Z0-9\-]/', ' ', $string);
$string = preg_replace('/^[\-]+/', '', $string);
$string = preg_replace('/[\-]+$/', '', $string);
$string = preg_replace('/[\-]{2,}/', ' ', $string);
return $string;
}

Best of luck
