PHP mysql_free_result() Function
Complete PHP MySQL Reference
Definition and Usage
The mysql_free_result() function frees memory used by a result handle.
This function returns TRUE on success, or FALSE on failure.
Syntax
mysql_free_result(data)
| Parameter | Description |
|---|---|
| data | Required. Specifies which result handle to free. The result handle is the return from the mysql_query() function |
Tips and Notes
Tip: PHP automatically releases the memory used by result handles at the end of the script. However, this function can be useful when you want to free up memory between large queries.
Example
<?php
$con = mysql_connect("localhost", "peter", "abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db("test_db",$con);
$sql = "SELECT * from Person";
$result = mysql_query($sql,$con);
print_r(mysql_fetch_row($result));
// Free memory
mysql_free_result($result);
$sql = "SELECT * from Customers";
$result = mysql_query($sql,$con);
print_r(mysql_fetch_row($result));
mysql_close($con);
?>
$con = mysql_connect("localhost", "peter", "abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db("test_db",$con);
$sql = "SELECT * from Person";
$result = mysql_query($sql,$con);
print_r(mysql_fetch_row($result));
// Free memory
mysql_free_result($result);
$sql = "SELECT * from Customers";
$result = mysql_query($sql,$con);
print_r(mysql_fetch_row($result));
mysql_close($con);
?>
