Desired result is:

abc.id as od

Solution

  • You can use the following regex pattern to select the string :

    (.*?)(?:\sas\s)(.*?)$

    ­

    input        >>  abc.id as od
regex search >>  (.*?)(?:\sas\s)(.*?)$
replace with >>  $1$2
output       >>  abc.idod

    see demo / explanation

    PHP

    $re = '/(.*?)(?:\sas\s)(.*?)$/';
$str = 'abc.id as od';
$subst = '$1$2';
$result = preg_replace($re, $subst, $str);
echo $result;
