<?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);
?>

注: 在 PHP 5.0.0 之前的版本必须使用 ocicolumnname() 替代本函数。该函数名仍然可用,为向下兼容作为 oci_field_name() 的别名。不过其已被废弃,不推荐使用。
