Example 1. ocinumcols() example

<?php   
    echo "<pre>\n";   
    $conn = OCILogon("scott", "tiger");
    $stmt = OCIParse($conn, "select * from emp");
    OCIExecute($stmt);
    while (OCIFetch($stmt)) {
        echo "\n";   
        $ncols = OCINumCols($stmt);
        for ($i = 1; $i <= $ncols; $i++) {
            $column_name  = OCIColumnName($stmt, $i);
            $column_value = OCIResult($stmt, $i);
            echo $column_name . ': ' . $column_value . "\n";
        }
        echo "\n";
    }
    OCIFreeStatement($stmt);  
    OCILogoff($conn);   
    echo "</pre>";
?>

Note: This function was renamed to oci_num_fields() after PHP >= 5.0.0. For downward compatibility ocinumcols() can also be used. This is deprecated, however.
