php - Variable invisible outside a function -


i have written query customer information database want use on page. don't want have copy , paste other page use it.

i have looked @ function don't know how variables out of function.

this current function:

function getcustomer($customerid) {  $getcustomer = mysql_query("select * hire_customers id='".$customerid."'"); $fetch = mysql_fetch_assoc($getcustomer);  $cust_firstname = $fetch['firstname']; $cust_lastname =  $fetch['lastname']; $cust_address =   $fetch['address']; $cust_town =      $fetch['town']; $cust_postcode =  $fetch['postcode']; $cust_cont1 =     $fetch['contact1']; $cust_number1 =   $fetch['contactnumber1']; $cust_cont2 =     $fetch['contact2']; $cust_number =    $fetch['contactnumber2']; $cust_email =     $fetch['email']; $cust_idform1 =   $fetch['idform1']; $cust_idnfo1 =    $fetch['idinfo1']; $cust_idform2 =   $fetch['idform2']; $cust_idinfo2 =   $fetch['idinfo2']; $cust_enterdby =  $fetch['enteredby'];   }

this customer page

getcustomer($customerid);  echo $cust_firstname;

but nothing echoed out.

do need looking @ class or object this? have gone wrong function.

what have php file customer functions (update, select, etc) in 1 place.

i think should return $fetch , access variable outside of function.

function getcustomer($customerid) {     $customerid = mysql_real_escape_string($customerid);     $getcustomer = mysql_query("select * hire_customers id='".$customerid."'");     $fetch = mysql_fetch_assoc($getcustomer);     return $fetch; }  $data=getcustomer($customerid);  echo data['firstname'];
