PHP strrchar

[Markpyro]

edit (I realize that I spelled the function wrong in the title, I know it's not supposed to be spelled that way)

I have a php file, that when you start it, finds data from a text file, and is supposed to find the last line of text (appears as last line when presented in html, as is divided by <br>'s) and put it into an image.

Here's a snippet that I'm having problems with:

$data=fread($o,filesize($filename));
$find = '>';
$string = $data; // Data is set at this point
$string = strrchr($data,$find); // Poof! Gone!
$string = ShortenText($string);


Okay, here's the definition via PHP.Net of the function, Strrchr:

strrchr -- Find the last occurrence of a character in a string,
This function returns the portion of haystack which starts at the last occurrence of needle and goes until the end of haystack.


Now, when If I echo $data before it's modified, it looks fine. Once I apply the function to it, though, it dissapears. I just want to gather a portion of $data, the last line, and display it in an image. But, for some reason, strrchr doesnt output anything. Wtf?

I did some quick tests and if the second parameter of strrchr doesn't exist, strrchr won't output anything. Without any sample data that doesn't work though, it's impossible to debug.

I don't know why your code doesn't work (I've never used strrchr), but here's how I would do it.


$data = file_get_contents("filename.txt");
$items = explode("<br>", $data);
$thelastline = end($items);


That should work fine but may take longer... though I doubt you'll notice unless your file is big.

Thanks a bunch, I got it to work now ^_^

One more thing- is there a way I can run a PHP file from a different PHP file? This script that I just fixed updates an image, but I want it to go in my signiture. Since I cant link PHP files in my signiture, I'd like every time I open a different file for the first to run and update the image.

It may be possible to do that using curl (http://us2.php.net/curl), but I don't know enough about curl to be of much help there. Good luck if you give it a try :)

Nevermind, found a way around my problem :P

I guess that works :P

[Markpyro]

It does :), no hassle remembering either. Found a wonderful firefox extension.

What's it called?

[Markpyro]

Signature. Just that. Simple right click, and it inserts all the text you need. I'm studying how to make the extensions themselves so I can have it automatically insert on every textbox on certain pages, but I'm still working on that :P

You can tell a PHP page to send a header that tells the browser it's an image. The rest of the PHP code should be used to display the image.

Or is this not what you wanted at all?

[Markpyro]

Not at all :/
