    It says “Choose php version 5.3.0” – so…. how do you do that? And/or what does it mean?

  3. Julian

    “Choose php version 5.3.0” mean: right click on wamp icon, PHP, choose PHP 5.3.0

    Hi, Firstly Thanks for this helpful topic
    i’ve stoped in the step number 12 “Check if PEAR path is correct in php.ini , and modify accordingly.” my wamp server now in yellow color when i went to php.ini “right click on wamp icon, i’ve chosen PHP, and click on php.ini” i’ve searched for PEAR and i’ve found this paragraphe :
    ; UNIX: “/path1:/path2”
    ;include_path = “.:/php/includes”
    ; Windows: “\path1;\path2”
    ;include_path = “.;c:\php\includes”
    ; PHP’s default setting for include_path is “.;/path/to/php/pear”
    ; http://php.net/include-path

    and i’ve changed it to this :

    ; UNIX: “/path1:/path2”
    ;include_path = “.:/php/includes”
    ; Windows: “\path1;\path2”
    ;include_path = “.;C:\wamp\bin\php\php5.3.6\PEAR”
    ; PHP’s default setting for include_path is “.;/path/to/php/pear”
    ; http://php.net/include-path

    and i’ve done this step :”13. Restart WAMP server.”

    but the wampserver still in yellow

    N.B : i’ve done all the steps successfully except the step number 12

    plz if you ‘ve a solution for this situation i’m waiting you ..
    Thanks again.

    You need to UN-comment the line:
    ;include_path = “.;C:\wamp\bin\php\php5.3.6\PEAR”

    which will be
    include_path = “.;C:\wamp\bin\php\php5.3.6\PEAR”

    Hi, thanks for your reply,
    i do what you say but without any result (the wampserver still in yellow color ) :s

  7. Julian

    well, you should check apache error log, why is not starting
    Or even better, ask directly on wamp support forum.

    Honestly, we dropped WAMP in favor of Zend Server, as we got development licenses for ZCE’s.

  8. Marouane

    Ok this is a good idea, thanks again and good luck :)

    Wamp is nice, but a miss when you want to upgrade. We are in 2013, few lines of codes to detect previous intallations, whatever the path, and deal intelligently with the inifiles is so difficult ?
    It is so painfull to upgrade, when you do not remember and old configuration.

    Hi Julian,

    I just want to know if the step that you have posted from 5.0 to 5.3 is still available to apply converting version 5.3.4 to version php5.5.4? I followed the step and it seems is not working in my end. The Wamp Server is not turning to GREEN icon. It will just pause to ORANGE icon. I tried to connect with localhost in browser and still is not working. Please advise and help.

  14. Julian

    We are not using WAMP anymore in our company, everybody swiched to Zend Server. No idea if will work with 5.5.4, my guess is that will NOT work , at least not yet.
    PHP 5.5.x is quite a major leap

  15. zatom alzoolano

    working method. thanx a 1.000.000
    i used to upgrade from php5.3.0 to php5.3.3.
