mysql_list_processesList MySQL processes


This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:


mysql_list_processes(resource $link_identifier = NULL): resource|false

Retrieves the current MySQL server threads.



The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() had been called with no arguments. If no connection is found or established, an E_WARNING level error is generated.

Return Values

A result pointer resource on success or false on failure.


Example #1 mysql_list_processes() example

= mysql_connect('localhost', 'mysql_user', 'mysql_password');

$result = mysql_list_processes($link);
while (
$row = mysql_fetch_assoc($result)){
printf("%s %s %s %s %s\n", $row["Id"], $row["Host"], $row["db"],
$row["Command"], $row["Time"]);

The above example will output something similar to:

1 localhost test Processlist 0
4 localhost mysql sleep 5

You can achieve the equivalent of the mysql_list_processes() function for MySQLi in php using:
function mysqli_list_processes(){
if ($res =$this->mysqli->query($query)){
while ($row = $res->fetch_assoc()) $recs[$i++] = $row;
return $recs;
} else {
return false;
