Question

i have a csv file containing telephone numbers.

There is about 15 numbers with the area code +44 and 20 numbers beginning with +64 (there are about 40 area codes). i need to echo one number of each set and drop the remains.

i loaded all the content using fgetcsv(). but i cant find a way to do the filtering part. can some please give me an idea how to sort this out in php?

Try this replace $numbers with your csv file content.

$numbers = array('+1134124', '[phone]', '[phone]','[phone]','[phone]','[phone]','[phone]','[phone]');                          

$final = array();

$received = array();

foreach($numbers as $snKey => $snValue )
{

    $snCode = substr($snValue,0,3);

    if(in_array($snCode,$received))
        continue;
    else
    {
        $received[] = $snCode;
        $final[] = $snValue;
    }
}
print_r($final);
