oci_fetch()
(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)
Fetches the next row into result-buffer
说明
oci_fetch(resource $statement): bool
oci_fetch()获取下一行(对于 SELECT 语句)到内部结果缓冲区。
Note:在 PHP 5.0.0 之前的版本必须使用ocifetch()替代本函数。该函数名仍然可用,为向下兼容作为oci_fetch()的别名。不过其已被废弃,不推荐使用。
参数
- $statement
有效的 OCI8 报表标识符由oci_parse()创建,被oci_execute()或REF CURSORstatement 标识执行。
返回值
Returns TRUE
on success or FALSE
if there are no more rows in the$statement.
范例
Example #1 oci_fetch() with defined variables
<?php $conn = oci_connect('hr', 'welcome', 'localhost/XE'); if (!$conn) { $e = oci_error(); trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR); } $sql = 'SELECT location_id, city FROM locations WHERE location_id < 1200'; $stid = oci_parse($conn, $sql); // The defines MUST be done before executing oci_define_by_name($stid, 'LOCATION_ID', $locid); oci_define_by_name($stid, 'CITY', $city); oci_execute($stid); // Each fetch populates the previously defined variables with the next row's data while (oci_fetch($stid)) { echo "Location id $locid is $city<br>\n"; } // Displays: // Location id 1000 is Roma // Location id 1100 is Venice oci_free_statement($stid); oci_close($conn); ?>
Example #2 oci_fetch() with oci_result()
<?php $conn = oci_connect('hr', 'welcome', 'localhost/XE'); if (!$conn) { $e = oci_error(); trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR); } $sql = 'SELECT location_id, city FROM locations WHERE location_id < 1200'; $stid = oci_parse($conn, $sql); oci_execute($stid); while (oci_fetch($stid)) { echo oci_result($stid, 'LOCATION_ID') . " is "; echo oci_result($stid, 'CITY') . "<br>\n"; } // Displays: // 1000 is Roma // 1100 is Venice oci_free_statement($stid); oci_close($conn); ?>
注释
Note:In PHP versions before 5.0.0 use ocifetch() instead.在当前版本中,旧的函数名还可以被使用,但已经被废弃并不建议使用。
