You need to bind your value without single quotes and then concatenate your bound value for the like comparison:

 $keyword="test";
 $stmt=oci_parse($connection,"SELECT *  
 FROM tableName where id=:id and (dataDetails like '%' || :key1 || '%' or  textData like '%' || :key1 || '%' or  name like '%' || :key1 || '%') and lang = :lang ");
       oci_bind_by_name($stmt, ':id', $id);
       oci_bind_by_name($stmt, ':key1', $keyword);
       oci_bind_by_name($stmt, ':lang', $lang);
       oci_execute($stmt, OCI_DEFAULT);
