  • Quickest way to run a linux dev-environment inside windows

    - by Industrial
    Hi everyone, I get more and more trouble from running WAMP on my XP computer to solve my local development needs. It feels like as more and more things just go wrong or could not be installed at all to a Windows version of PHP. I have been looking for an alternative and found AndLinux plus this link. Would it be a good idea to get an Ubuntu box running virtually on my XP computer to simulate the production web server?

  • PHPUnit not working with netbeans 7.2.1

    - by user1578653
    I have just upgraded to netbeans 7.2.1 and phpunit is not working. I get the error:- Cannot run program C:\wamp\bin\php\php5.3.5\PEAR\phpunit-skelgen": CreateProcess error=193, %1 is not a valid Win32 application" when I try to generate PHPUnit tests. The only thing I can think of is that I seem to have a 64 bit version of netbeans installed - could this be the problem? If so, can anyone point me to a 32 bit version, because I couldn't see one on the website?

  • Use case for output buffering as the correct solution to "headers already sent"

    - by kemp
    I see (not just on this site) a lot of question from inexperienced PHP programmers about the infamous "headers already sent... output started at" error, and many people suggest using ouput buffering as a solution. In my experience I have never found a situation where that error wasn't caused by a flow in the program's logic. Are there cases where output buffering is actually the correct solution?

    - by Trickerie
    I'm an experienced iOS programmer and have recently began to dabble in web development to expand my horizons.

  • Why is phpseclib producing incompatible certs?

    - by chacham15
    Why is it that when I try to use a certificate/key pair generated from phpseclib, the OpenSSL server code errors out? Certs/Keys generated from OpenSSL work fine. How do I fix this? Certificate/Key Generation taken straight from phpseclib documentation: <?php include('File/X509.php'); include('Crypt/RSA.php'); // create private key / x.509 cert for stunnel / website $privKey = new Crypt_RSA(); extract($privKey-createKey()); $privKey-loadKey($privatekey); $pubKey = new Crypt_RSA(); $pubKey-loadKey($publickey); $pubKey-setPublicKey(); $subject = new File_X509(); $subject-setDNProp('id-at-organizationName', 'phpseclib demo cert'); //$subject-removeDNProp('id-at-organizationName'); $subject-setPublicKey($pubKey); $issuer = new File_X509(); $issuer-setPrivateKey($privKey); $issuer-setDN($subject-getDN()); $x509 = new File_X509(); //$x509-setStartDate('-1 month'); // default: now //$x509-setEndDate('+1 year'); // default: +1 year $result = $x509-sign($issuer, $subject); echo "the stunnel.pem contents are as follows:\r\n\r\n"; echo $privKey-getPrivateKey(); echo "\r\n"; echo $x509-saveX509($result); echo "\r\n"; ?

    Whats a better way to store textual data, such as comments, user profile fields that require them to type something in, etc? Store the escaped data right away (using htmlspecialchars in php for example), or put it thru the same function before its echoed out?

  • What is the purpose of abstract classes?

    - by SpikETidE
    I am trying to learn OOP in PHP, and I have some confusion about interfaces and abstract classes. They both contain no implementations, only definitions, and should be implemented through their sub-classes. What part of abstract classes clearly distinguishes them from interfaces? Also, due to their apparent similarities, based on what reasons should I decide to use one over the other?

  • Mustache vs other engines. Maybe I should use another template engine?

    - by marcioAlmada
    I'm passing an object to mustache and this object has a method with one parameter. Is something like this possible with Mustache and PHP? {{object.method(parameter)}} If it gets too laborious to achieve this with Mustache, what template engine would you recommend? Remember I need to pass parameters to object methods while in the view context (like we do with helpers). The nearest as possible to mustache syntax is welcome.

  • Monitor AJAX calls via cURL

    - by iamdadude
    Is it possible to monitor a page's AJAX calls via cURL in PHP? For example, if I connect to a website that uses lots of AJAX to pull content, can I connect to the site via cURL, have it wait a couple of seconds until the AJAX requests are done and analyze the request that the site made?
