Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

Thread: PHP: fopen() and fread()

  1. #1

    PHP: fopen() and fread()

    hi,

    in my application there is a code block that looks something like this:

    PHP Code:
    $fp fopen($rssURL,"r"
     
    while (
    $data fread($fp4096))
    {
        
    //process data

    the $rssURL is the location of an rss file on some website's server.

    so my question is: when does fopen() and/or fread() time out? is there any way to detect this? i don't want my script to sit there for hours trying to open one 2K file? can i set the limit?

    thanks

    php has it's max execution time - 30s
    after this time, script is stopped

    btw
    i prefer usign
    PHP Code:
    file_get_contents ($rssURL); 
    than fopen () + fread ()

  3. #3
    yeah but i want to stop trying to open the file after about a second or two...ya know?

  4. #4

    here it goes (not sure if working):
    PHP Code:
    <?php

    $rssURL 
    "ulr_gose_here";
    $maxtime 3//3 seconds in this case
    $time_start time ();

    if (@
    $fp fopen ($rssURL"r")) {
        while (
    $data fread ($fp4096) && (time () - $time_start) < $max_time) {
            
    //process data
        
    }
    }

    ?>
    edit: fixed "fopen" statement

    it needs to be on the fopen()...

    let's say the site with the RSS file i'm trying to pull is down. then i obviuosly can't pull the RSS file. it's weird though because it doesn't cause an error and die. it just sits there.

    ?

    look @ the code AGAIN...

    You may want to consider launching a CRON script that pulls the data and caches it locally, and then using your web code to parse the script once it's already on the filesystem.

    This has a few advantages -
    1) It doesn't slam their server if your server is busy.
    2) It doesn't hang your site if their server is down.
