oci_fetch_array
(PHP 5)
oci_fetch_array -- Returns the next row from the result data as an associative or numeric array, or both
Description
array
oci_fetch_array ( resource statement [, int mode] )
Returns an array, which corresponds to the next result row or FALSE in case of error or there is no more rows in the result.
oci_fetch_array() returns an array with both associative and numeric indices.
Note: This function sets NULL fields to PHP NULL value.
Optional second parameter can be any combination of the following constants:
|
OCI_BOTH - return an array with both associative and numeric indices (the same as OCI_ASSOC + OCI_NUM). This is the default behavior. |
|
OCI_ASSOC - return an associative array (as oci_fetch_assoc() works). |
|
OCI_NUM - return a numeric array, (as oci_fetch_row() works). |
|
OCI_RETURN_NULLS - create empty elements for the NULL fields. |
|
OCI_RETURN_LOBS - return the value of a LOB of the descriptor. |
Default
mode is
OCI_BOTH.
It should be mentioned here, that oci_fetch_array() is insignificantly slower, than oci_fetch_row(), but much more handy.
Note: Don't forget, that Oracle returns all field names in uppercase and associative indices in the result array will be uppercased too.
Example 1. oci_fetch_array() with OCI_BOTH example <?php
$connection = oci_connect("apelsin", "kanistra");
$query = "SELECT id, name FROM fruits";
$statement = oci_parse ($connection, $query);
oci_execute ($statement);
while ($row = oci_fetch_array ($statement, OCI_BOTH)) {
echo $row[0]." and ".$row['ID']." is the same<br>";
echo $row[1]." and ".$row['NAME']." is the same<br>";
}
?> |
|
Example 2. oci_fetch_array() with OCI_NUM example <?php
$connection = oci_connect("user", "password");
$query = "SELECT id, name, lob_field FROM fruits";
$statement = oci_parse ($connection, $query);
oci_execute ($statement);
while ($row = oci_fetch_array ($statement, OCI_NUM)) {
echo $row[0]."<br>";
echo $row[1]."<br>";
echo $row[2]->read(100)."<br>"; //this will output first 100 bytes from LOB
}
?> |
|
Example 3. oci_fetch_array() with OCI_ASSOC example <?php
$connection = oci_connect("user", "password");
$query = "SELECT id, name, lob_field FROM fruits";
$statement = oci_parse ($connection, $query);
oci_execute ($statement);
while ($row = oci_fetch_array ($statement, OCI_NUM)) {
echo $row['ID']."<br>";
echo $row['NAME']."<br>";
echo $row['LOB_FIELD']."<br>"; //this will output "Object id #1"
}
?> |
|
Example 4. oci_fetch_array() with OCI_RETURN_LOBS example <?php
$connection = oci_connect("user", "password");
$query = "SELECT id, name, lob_field FROM fruits";
$statement = oci_parse ($connection, $query);
oci_execute ($statement);
while ($row = oci_fetch_array ($statement, OCI_NUM)) {
echo $row[0]."<br>";
echo $row[1]."<br>";
echo $row['LOB_FIELD']."<br>"; //this will output LOB's content
}
?> |
