oci_field_name — 返回字段名
$statement
, int $field
)oci_field_name() 返回与字段数字索引(从 1 开始)相对应的字段名。
Example #1 oci_field_name() 例子
<?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:
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。
参见 oci_num_fields() , oci_field_type() 和 oci_field_size() 。

This does not work for empty tables.

Beware, the field index starts with 1, not 0. It's a bit counter-intuitive.
