This is a quick function I wrote to parse out the 'microtime()' feature, and deal with the results mathmatically. Since microtime() returns the milliseconds, then a space, then the unix timestamp, using the results from microtime() itself weren't conducive to quick math. We had some pages here that we needed to time down to the millisecond, so we used this. :) <? function getmicrotime() { $temparray=split(" ",microtime()); $returntime=$temparray[0]+$temparray[1]; return $returntime; } ?>

Web based calendar. The calendar has 2 functions. The first is to view the whole month, the second is used when you click on a specific day in the month, which will then take you to the hour breakout for that day and the previous and next day <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Joe Harman's Calendar</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <style type="text/css"> <!-- body { font-family: Tahoma, Verdana, Helvetica, Arial, sans-serif; font-size: 11px; color: #000000; } --> </style> </head> <body leftmargin="1" marginwidth="1"> <?php // Created By Joe Harman - cjharman@gmail.com function Cal_Month() { // Get Today's Date $todays_date = getdate(); // Determine what month to display if(isset($_GET['month'])) { $resolve_time = "1 ".$_GET['month']."

Time your PHP scripts. I took the "dealing with microtime" function and created a class. Now it is easy to start, stop and print out the elapsed time. Great for timing PHP scripts. <? class BC_Timer{ //properties var $stime; var $etime; //methods //get_microtime function taken from Everett Michaud on Zend.com function get_microtime(){ $tmp=split(" ",microtime()); $rt=$tmp[0]+$tmp[1]; return $rt; }//end get_microtime() function start_time(){ $this->stime = $this->get_microtime(); }//end start_time function end_time(){ $this->etime = $this->get_microtime(); }//end start_time function elapsed_time(){ return ($this->etime - $this->stime); }//end start_time }//end BC_Timer class ?>

PHP_Scheduler is a very simple class for storing timestamps at application-level. It can be useful in situations such as "I want to update a file not more than once every 15 minutes" or "I want to cache a database query and refresh it every 30 minutes." The class is very simple to use, simply look at the example. Feel free to contact me via email with questions/suggestions/bug reports. <?php /* PHP_Scheduler Version 0.5.1 Ryan Flynn (ryan@ryanflynn \|\| DALnet->#php->pizza_milkshake) Saturday, June 24 2001 This class was written to solve the problem of a standardized scheduling/timing mechanism in PHP that needed to be cross-OS compatible. For the moment it's nothing more than a simple timer, but I hope to build it into a cross-platform crontab-like class. We'll see. This class has been tested with PHP 4.0.x on Windows 2000/IIS and FreeBSD 4.2/Apache. Uses for this class would be along the lines of: "I need to update a file not more than every 15 minutes" "I want to cache my qery results to increase performance but refresh every 30 minutes" ================================================================================= An example of the use of this class: //this script shows the # of registered users $sch=new Scheduler("news"); //create new sched obj $sch->set_increment("MINUTES", 30); //set to 30 minute increments $sch->start(); //put in motion - this will only actually 'start' the //counter if this is the first "news" Scheduler created, //otherwise it will leave the existing "news" time alone if($sch->times_up()){ //if it's been 30 or more minites since //last access to DB we get fresh results $rs=mysql_query("SELECT COUNT() AS users FROM tbl_users;"); //no error checking, sloppy! $rs2=mysql_fetch_array($rs); putenv("TOTAL_REGGED_USERS={$rs2[0]}"); } echo getenv("TOTAL_REGGED_USERS"); $sch->cleanup(); //kills object but not global var (so next pageview can access it) ================================================================================= WARNING: This may seem obvious, but you need to use diffnt strings to declare diffnt scheduler objects, i.e. if you have two pages using two diffn't scheds you cannot use the same string or it over-writes the other object's time. I absolutely encourage feedback and/or modification of this class to improve it.

This class allow very precise timing based on microtime() function, in a two-step very simple operation: Call it from your code with include("timer.class.php4"), Then start and stop timer before and after your code. static $timerGap = 0; // Merge both parts of a microtime() result into a float. // microtime() function returns a string like "0.324324 332144" // The first part is the milliseconds // The second part is the seconds elapsed from Jan 1st of 1970 function getmicrotime($mt) { list($a, $b) = explode(" ", $mt); return ((float)$a + (float)$b); } // Evaluate the time needed to retrieve start & stop timers. // Gap is the time needed to get start then stop time // Due to memory allocations involved in instance creation // of the object, evaluating the time slice needed for // timer initialization and destroy give more accurate results. function initGap() { global $timerGap; $timerGap = "GAPTEST"; //eqv 0 but not 0 $vmax = 0; $vmin = 1; for ($i=0;$i<10;$i++) { $subtest = NULL; //unalloc memory space $subtest = new timer(); $subtest->result(); $v = $subtest->result(); if ($v>$vmax) $vmax=$v; if ($v<$vmin) $vmin=$v; } $timerGap = $vmin; } class timer { var $tmStart = 0; // Start timestamp, microtime format var $tmStop = 0; // Stop timestamp, microtime format var $tmCount = 1; // Number of cycles in user's test loop var $tmGap = 0; // Gap used (taken from the result) // Initializes and start the timer // Call initGap if it hasn't been done before function timer($counter=1) { global $timerGap; if ($timerGap===0) initGap(); $this->tmGap = $timerGap; $this->tmCount = (int)($counter<=0?1:$counter); $this->tmStart = microtime(); } // Reset the start timer // Reevaluate Gap Time considering static calls function reset($counter=1) { $this->tmStop = 0; $this->tmCount = 1; $this->tmStart = microtime(); $this->tmGap = $this->result(); //more accurate gap $this->tmStop = 0; $this->tmCount = (int)($counter<=0?1:$counter); $this->tmStart = microtime(); } // Stops the timer and returns elapsed time // Multiple calls to the result function result() { $mt = microtime(); if ($this->tmStop===0) $this->tmStop = $mt; $tm1 = getmicrotime($this->tmStop); $tm2 = getmicrotime($this->tmStart); return ($tm1-$tm2-$this->tmGap)/$this->tmCount; } }
