(PHP 5, PECL OCI8 >= 1.1.0)
oci_fetch — Fetches the next row into result-buffer
说明
bool oci_fetch ( resource$statement
)
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 CURSOR statement 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。
