Unlike oci_fetch_all(), after using oci_fetch_assoc(), LOB columns (CLOB, BLOB) are NOT returned as strings but as Oci-Lob objects. You have to use Oci-Lob->read() or load() method in order to read column content.
(PHP 5, PHP 7, PHP 8, PECL OCI8 >= 1.1.0)
oci_fetch_assoc — Returns the next row from a query as an associative array
Returns an associative array containing the next result-set row of a query.
Each array entry corresponds to a column of the row. This function
is typically called in a loop until it returns false, indicating
no more rows exist.
Calling oci_fetch_assoc() is identical to
calling oci_fetch_array()
with OCI_ASSOC
+ OCI_RETURN_NULLS.
Returns an associative array. If there are no more rows in
the statement then false is returned.
示例 #1 oci_fetch_assoc() Example
<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$stid = oci_parse($conn, 'SELECT department_id, department_name FROM departments');
oci_execute($stid);
while (($row = oci_fetch_assoc($stid)) != false) {
echo $row['DEPARTMENT_ID'] . " " . $row['DEPARTMENT_NAME'] . "<br>\n";
}
oci_free_statement($stid);
oci_close($conn);
?>注意:
See oci_fetch_array() for more examples of fetching rows.
Unlike oci_fetch_all(), after using oci_fetch_assoc(), LOB columns (CLOB, BLOB) are NOT returned as strings but as Oci-Lob objects. You have to use Oci-Lob->read() or load() method in order to read column content.Here's a simple example of using the oci_fetch_assoc function for anyone who would like to see it.
<?php
$oconn = oci_connect('ora_user','ora_pass','ora_inst');
if (!$oconn){
$msg = "Cannot connect to Oracle ".oci_error();
} else {
$msg = "Connected to Oracle";
}
$select_stmt = "select username from user_table";
$stid = oci_parse($oconn, $select_stmt);
oci_execute($stid);
echo "<table border='1'>\n";
while ($row = oci_fetch_assoc($stid)) {
echo "<tr>\n";
echo "<td>". $row["USERNAME"] . "</td>\n";
echo "</tr>\n";
}
echo "</table>\n";
oci_free_statement($stid);
oci_close($oconn);
?>
Make sure you capitalize the column name for referencing the item in the associative array. Of course, this is just a simple example and you might want to do some processing on the data prior to output, but you get the idea here.
