Example 1. oci_field_type() example

<?php   
    $conn = oci_connect("scott", "tiger");
    $stmt = oci_parse($conn, "SELECT * FROM emp");
    oci_execute($stmt);
    
    echo "<table border=\"1\">";
    echo "<tr>";
    echo "<th>Name</th>";
    echo "<th>Type</th>";
    echo "<th>Length</th>";
    echo "</tr>";
   
    $ncols = oci_num_fields($stmt);
   
    for ($i = 1; $i <= $ncols; $i++) {
        $column_name  = oci_field_name($stmt, $i);
        $column_type  = oci_field_type($stmt, $i);
        $column_size  = oci_field_size($stmt, $i);
        
        echo "<tr>";
        echo "<td>$column_name</td>";
        echo "<td>$column_type</td>";
        echo "<td>$column_size</td>";
        echo "</tr>";
    }
       
    echo "</table>\n"; 
   
    oci_free_statement($stmt);  
    oci_close($conn);   
?>

Note: In PHP versions before 5.0.0 you must use ocicolumntype() instead. This name still can be used, it was left as alias of oci_field_type() for downwards compatability. This, however, is deprecated and not recommended.
