(PHP 5, PHP 7, PHP 8, PECL OCI8 >= 1.1.0)
oci_fetch — Fetches the next row into result-buffer
$statement
): booloci_fetch() 獲取下一行(對于 SELECT 語句)到內(nèi)部結(jié)果緩沖區(qū)。
注意:
在 PHP 5.0.0 之前的版本必須使用 ocifetch() 替代本函數(shù)。該函數(shù)名仍然可用,為向下兼容作為 oci_fetch() 的別名。不過其已被廢棄,不推薦使用。

示例 #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);
?>
示例 #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);
?>
注意:
In PHP versions before 5.0.0 use ocifetch() instead.
