Here is a code that prints time taken by each step in a simple mySQL query.
<?php
function connect_database()
{
$link = mysql_connect('www.mywebsite.com', 'db_local', 'password');
if (!$link)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db('db_local');
}
function disconnect_database()
{
mysql_close();
}
function get_table()
{
$sttime = microtime(true);
connect_database();
$timediff = round((microtime(true) - $sttime)*1000, 2);
print "Connect: \t\t{$timediff} ms\n";
$query1 = "SELECT * FROM categories ";
$sttime = microtime(true);
$table = mysql_query($query1);
$timediff = round((microtime(true) - $sttime)*1000, 2);
print "Query: \t\t{$timediff} ms\n";
$sttime = microtime(true);
disconnect_database();
$timediff = round((microtime(true) - $sttime)*1000, 2);
print "Disconnect: \t{$timediff} ms\n";
return $table;
}
$sttime = microtime(true);
get_table();
$timediff = round((microtime(true) - $sttime)*1000, 2);
print "Total: \t\t{$timediff} ms\n";
/*
---------OUTPUT---------
Connect: 82.82 ms
Query: 14.55 ms
Disconnect: 0.09 ms
Total: 97.65 ms
*/
