    PHP proxy

    19th September 2007

    PHP proxy is simple but good. I converted it into a proxy-function for one of my projects.

    Do pay attention to the comments, especially these two:

    I had issues with this script (and others) returning 0 for the bytesTotal in flash. Basically, the Content-Length header was absent from the response. By simply adding
    header(“Content-length: “.strlen($response)) before the echo, it resolved the issue. I don’t know if there is a more appropriate fix to account for character encoding, etc, but it seems to work.

    @Schimmi: Well, if you can add some checks there (like who is referring your script) and allow the access to whitelisted clients (served from your domain)… I think, you can totally make it used applications from same-domain….So it would not be open to world. Yeah above script doesn’t have those things.

    How to make PEAR work from behind an HTTP proxy (Windows and Linux)

    31st May 2007

    Earlier in one of my posts (Using PEAR HTTP_Client or HTTP_Request with HTTP proxy) I gave an example of using PEAR HTTP_Client and/or HTTP_Request from behind an http proxy. However, I didn’t tell how to make PEAR itself work properly from behind an HTTP proxy (e.g., for online operations like “pear upgrade-all”).

    So here’s that tiny missing bit of information.

    Windows:
    Launch regedit, navigate to HKEY_CURRENT_USER\Environment, and create a string value called PHP_PEAR_HTTP_PROXY. Modify that new value to hold the string like: http://proxy_username:proxy_password@proxy_server_address:proxy_port.

    Linux:
    In the Terminal/Konsole, execute (for a system-wide pear configuration)

    sudo pear config-set http_proxy http://proxy_username:proxy_password@proxy_server_address:proxy_port

    If your proxy password has symbols, special for the shell (e.g. question or exclamation mark) – enclose full proxy specifications with single-quotes, e.g.

    sudo pear config-set http_proxy ‘http://proxy_username:proxy_password@proxy_server_address:proxy_port’

    If your HTTP proxy server does not require authentication, then use http://proxy_server_address:proxy_port instead.

    I think the strings are completely self-explanatory; however, here’s an example of proxy (with authentication) specification: http://john.smith:CrAzYP433WoRd@192.168.0.1:3128.

    Directory-based random image rotation PHP script

    23rd May 2007

    Yesterday I needed to put together a rather simple PHP script: it would read the contents of a single pre-configured directory, and randomly select up to a pre-configured number of files. These files were images, and were just dumped as IMG tags into the webpage. I came up with a solution, shown below.

    The script is simple, but still it’s easier to use the ready solution than to write your own :).
    It is heavily commented, and should be easy to understand.

    Executing and checking background shell process from PHP

    23rd May 2007

    Found a nicely illustrated method for running a background shell command from PHP and continuously checking if the process is still running.

    Here’s sample code without explanations:

    1. function run_in_background($Command, $Priority = 0)
    2. {
    3.  if($Priority)
    4.   $PID = shell_exec("nohup nice -n $Priority $Command 2> /dev/null & echo $!");
    5.  else
    6.   $PID = shell_exec("nohup $Command 2> /dev/null & echo $!");
    7.  return($PID);
    8. }
    9.  
    10. function is_process_running($PID)
    11. {
    12.  exec("ps $PID", $ProcessState);
    13.  return(count($ProcessState) >= 2);
    14. }

    To run something like hmmsearch from the HMMER package, you’d do this:

    1. echo("Running hmmsearch. . .")
    2. $ps = run_in_background("hmmsearch $hmmfile $fastafile > $outfile");
    3. while(is_process_running($ps))
    4. {
    5.  echo(" . ");
    6.  ob_flush();flush();
    7.  sleep(1);
    8. }

    How to find absolute path on a web-server (using PHP)

    30th April 2007

    When using PHP, the simplest way to find the absolute path of your files/folders on the server is by creating a simple path.php file with the following contents (click on the “Plain text” box header for copy-pasting):

    1. <?php
    2. echo realpath(dirname(__FILE__));
    3. ?>

    Put the new file anywhere in the web-accessible folder on your server,
    then just access that file from your favourite web-browser – and you’ll have the absolute path shown to you.

    Alternatively, you may use the following code:

    1. <?php
    2. echo getcwd();
    3. ?>

    This also should display the absolute path on your server.

    Drupal internationalization (i18n) and localization (l10n)

    10th March 2007

    This is a collection of links related to the multiple-language content in Drupal CMS.

    i18n module
    i18n: Getting the whole thing to work : http://drupal.org/node/81094
    Patch: Translations of menu titles and descriptions: http://drupal.org/node/70919
    Translated links: http://drupal.org/node/67814
    i18n: menu not expanding with URL-Alias: http://drupal.org/node/80820

    There was an alternative module to i18n, but I cannot find it at the moment.
