oci_field_name()
(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)
返回字段名
说明
oci_field_name(resource $statement,int $field): string
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()。
Beware, the field index starts with 1, not 0. It's a bit counter-intuitive.
This does not work for empty tables.
