Hi, If you know that the characters are dots, just str_replace them with
nothing

$new = str_replace('.','','.a.b.c');

or if they are every other character , regardless of value, try:

$string = '.d.fjdghdjtgkfdhfr';
$new = '';
for ($n = 2 to len($string)+1){
if ($n%2==0) $new .= substr($string,$n-2,1);
}

this will remove all the odd characters,
testing for $n modulus 2 ==1 will take out the even characters
