$conn = oci_connect('abc', 'test', 'test');
$sql  = ' begin balance1(:cardnumber); end; ';
$stmt = oci_parse($conn,$sql);
 
oci_bind_by_name($stmt,':cardnumber',$cardnumber,32);
 
$cardnumber = '5xxxxxxxxxxxxx';

try adding  '&' in the following statements
 
oci_bind_by_name($stmt,':cardnumber',&$cardnumber,32);
oci_bind_by_name($stmt,':trnamntstr',&$trnamntstr,32);

I try to change Function balance 1 to Procedure balance

Definition for balance :

create or replace procedure balance(v_cardnumber in varchar2,trnamntstr out varchar2 ) is
.....
end balance

and the Php i change is :

<?php
$conn = oci_connect('aaa', 'bbb', 'test') or die('Cannot connect') ;
$sql  = 'BEGIN balance(:cardnumber,:trnamntstr); END;';
$stmt = oci_parse($conn,$sql);

oci_bind_by_name($stmt,':cardnumber',$cardnumber,32);
oci_bind_by_name($stmt,':trnamntstr',$trnamntstr,32);

$cardnumber = '5212345678991111';
oci_execute($stmt);
print "$trnamntstr\n";
?>


But the output is nothing ?
Would anybody have idea ?

CHECK WHETHER THE PROCEDURE IS GIVING PROPER OUTPUT by executing it in sqlplus;
 set serveroutput on
decare
v_output varchar2(100);
begin
 balance( '5212345678991111',v_output );
dbms_output.put_line(v_output);
end;

try this
use double quotes inseted of single quotes
oci_bind_by_name($stmt,":cardnumber",&$cardnumber,32);
oci_bind_by_name($stmt,":trnamntstr",&$trnamntstr,32);

Have you tried as SQL
$sql  = 'balance1(:cardnumber)';
Or have you read http://www.php.net/manual/en/function.oci-new-cursor.php

additional note:
the & might not be needed if you correctly define the variables before usage. So this might also work if you want to try. Would be intersting to know if that also works.
$conn = oci_connect('abc', 'abc', 'test') or die('Cannot connect') ;
$sql  = 'BEGIN balance(:cardnumber,:trnamntstr); END;';
$stmt = oci_parse($conn,$sql);
 
$cardnumber = '52131111111111';
$trnamntstr = null;
oci_bind_by_name($stmt,':cardnumber',$cardnumber,32);
oci_bind_by_name($stmt,':trnamntstr',$trnamntstr,32);
 
oci_execute($stmt);
print "$trnamntstr\n";
