oci_num_fields() example
<?php // Create the table with: // CREATE TABLE mytab (id NUMBER, quantity NUMBER); $conn = oci_connect("hr", "hrpwd", "localhost/XE"); if (!$conn) { $m = oci_error(); trigger_error(htmlentities($m['message']), E_USER_ERROR); } $stid = oci_parse($conn, "SELECT * FROM mytab"); oci_execute($stid, OCI_DESCRIBE_ONLY); // Use OCI_DESCRIBE_ONLY if not fetching rows $ncols = oci_num_fields($stid); for ($i = 1; $i <= $ncols; $i++) { echo oci_field_name($stid, $i) . " " . oci_field_type($stid, $i) . "<br>\n"; } // Outputs: // ID NUMBER // QUANTITY NUMBER oci_free_statement($stid); oci_close($conn); ?>
