Text File to array

Dawg · Posted: Mon Jul 25, 2005 11:01 pm

Code:

<?
$newline = " ";
$arr=file("cache/test_txt.txt");

foreach($arr as $str)
{
list($name,$message)=explode("|",$str);
echo $name,$message,$newline,$newline;
}

?>

This array outputs the data.....

time2005-07-25 16:00:35

lat 34.14

lon -77.71

wind_speed 1.9

The hard part is figuring out how to break the array apart so I can then display the $name as NAME

Let me say that again.....
Currettly I am displaying

wind_from_direction 181

I wish to display.....

Wind From Direction
181

Could you be so kind as to point me in the proper direction? I have been messing with this all night! It's killing me!

Thank You for your time!!

Raven is Da Man!

Thank You!

Maybe one day I will grow up to be a "Raven"!!

LOL

When I get finished with this script....Can I talk you into a once over of it before I release it to make sure I did not do anything STUPID! Having the Master review the work with comments is a HAPPY thang!

Greetings Raven, and All,

I have been working on this script for a while and I have it working....sort of.

Here is the deal. One of the local .EDU's has several buoys in the water and several more planned to come online soon. I have made a deal with them to display their data.

This works but it takes forever to run. 6-8 secs and you have to hit reload to get the current data if it has timed out.

/*-----------------------------AIR TEMP-----------------------------------*/

$q = 7200; //cache time delay in seconds, 3600=one minute

$filesize = filesize("cache/ILM2air_temp1-day.png");
$lastvisit = filemtime("cache/ILM2air_temp1-day.png");
$currenttime = getdate(time());
$currentdate = $currenttime["0"];
$difference = $currentdate - $lastvisit;
$diff = $q-$difference;
$hrs = intval($diff/3600);
$min = intval(($diff-($hrs*3600))/60);

$ufurl = "http://www.cormp.org/images2/";
$content = "ufurl: $ufurl ";

$imagefile = "/cache/ILM2air_temp1-day.png";

if (!($textfile = fopen( "$ufurl", "r"))) {
$content .= "$ufurl could not be opened ";
die();
}

while (!feof($textfile)) {
$line = fgets($textfile, 1500);
if (eregi( ".*<IMG ALT=\"ILM2\".*SRC=\"(.*)\">.*", $line, $out)) {
$imagefile = $out[1];
break;
}
}

fclose($textfile);

$content = "";
$content .= "<A HREF=\"http://www.cormp.org/images2/ILM2air_temp1-day.png\" target=\"_blank\"><IMG SRC=\"$imagefile\" alt=\"Data By CORMP\"></A>";
$content .= "<tr><td align=\"center\">Next Update $hrs hrs $min mins";
echo $content;
$content .= "";

if ( ($difference < $q) AND ($filesize != 0) )
{ }
elseif ( ($difference > $q) OR ($filesize == 0) )

{
$fc = fopen("cache/ILM2air_temp1-day.png", "wb");
$file = fopen ("http://www.cormp.org/images2/ILM2air_temp1-day.png", "rb");
if (!$file) {
$info = "E";
exit;
}
else
{
while (!feof ($file)) {
$line = fread ($file, 4096);
fwrite($fc,$line);
}
}
fclose($fc);
fclose($file);

$info = "F"; }
?>

Like I said this works......just not very well. I have about 10 of these calls on a single page......the text file we talked about earlier and all of the graphs that go along with it.

My guess is that I need to turn the time part of this script into a function and then call that function for each part of the script that needs to be updated. In order to get around the hitting reload to get the current data I guess I will have to put the time function in something that is called more often....like the config file or the main file and then have this script call it?????

This is where I really get lost. So I have come to you. I do not wish for you to code it for me (althought it would be easier on both of us) I really wish to learn so I do not have to ask.

Do I have the right idea here or am I barking up the wrong tree?

Would you be kind enough to point me in the right direction?

I can't really get the picture of what this does, unfortunately. I would have to set it up locally and play with it. But, you could install timers throughout the code to profile different sections to see where the time is being eaten up. Then, armed with exactly where it takes the time, you can work on making that section more efficient. Make sense?

Raven · Posted: Tue Aug 02, 2005 4:47 am

It took 4.5 seconds for me. With all that graph work I'd say that is very respectable.

Dawg · Posted: Tue Aug 02, 2005 5:08 am

WOW....You are fast....

Did you notice the timers under each one.....once they count down to 0 they go to -4 hrs 32 mins or what ever the time was of it's last refresh.

Currently.....if it has been longer than 2 hrs.....and you pull the page....it does not refresh the graphs until you hit the refresh button.

What I would realy like it to do is check the time before it displays the graphs to make sure it is up to date then display the up to date info not the old graphs......

Thank You for your time!

Talking about the time to display the graphs....

If it was doing all the graphing work on the fly...I would agree but these are premade images....one I just looked at was only 4713 bytes...even if there are 10 of them on a page....that is not that much info.

I get much faster load times in my gallery or front page and I know my front page is loaded down. It just seemed that these pages were loading real slow. I was guessing I made an error in the code somewhere.

Then I would profile different sections of the code to see where the time is being eaten up. That should solve the riddle Wink

Here is an easy to use Script timer I found....

<?php

// Filename: STOPWATCH.PHP
// =======================

// Start TIMER
// -----------
$stimer = explode( ' ', microtime() );
$stimer = $stimer[1] + $stimer[0];
// -----------

/* ------------------------------------- */
// Add your PHP script and/or content here
/* ------------------------------------- */

// End TIMER
// ---------
$etimer = explode( ' ', microtime() );
$etimer = $etimer[1] + $etimer[0];
echo '';
printf( "Script timer: %f seconds.", ($etimer-$stimer) );
echo '';
// ---------

?>

My results were............

Script timer: 0.511784 seconds.
Script timer: 0.519668 seconds.
Script timer: 0.508725 seconds.
Script timer: 0.509885 seconds.
Script timer: 0.517278 seconds.
Script timer: 0.520487 seconds.
Script timer: 0.602185 seconds.
Script timer: 0.520353 seconds.

More or less I am burning .5 secs per image. That is the time to figure out the time....pull the image....and display it.

Would I be better off the change the time portion of each of these to a function and then call that function for each graph?

If so......and this is my timing code....

$q = 7200;

$filesize = filesize("cache/ILM2air_temp1-day.png");
$lastvisit = filemtime("cache/ILM2air_temp1-day.png");
$currenttime = getdate(time());
$currentdate = $currenttime["0"];
$difference = $currentdate - $lastvisit;
$diff = $q-$difference;
$hrs = intval($diff/3600);
$min = intval(($diff-($hrs*3600))/60);

I do not know how to make a $ to decide whether or not to update.

In the orginal script I guess this one is doing it....

$content .= "";
if ( ($difference < $q) AND ($filesize != 0) )
{ }
elseif ( ($difference > $q) OR ($filesize == 0) )

But I do not think that would work overall because there are a lot of content calls in this script.

Could you point me in the right direction?

Thank you for your time!
