PHP custom debugging functions

Iman — Mon, 12 Jul 2010 15:40:45 +0000

Here is another debugging helper for Symfony, CodeIgniter, Kohana and Zend frameworks or your applications. Normally you would use var_dump() or print _r() for debugging but dumping the data without xdebug always a pain.

I use these custom functions depending on type of data whether an array or a class to debug my code which makes it more friendly and human-readable.

<?php

function my_print_r ($param, $bool = TRUE) {

    pre( print_r($param, $bool), FALSE);

}

function my_var_dump ($param) {

    pre(var_dump($param));

}

function my_debug ($param) {

    if (is_object($param)) {

        pre('Object: ['.get_class($param). '] => '

           . print_r(array_keys(get_object_vars($param)), TRUE), FALSE);

    }

}

function my_debug_in ($param) {

    if (is_object($param)) {

        pre('Object: [' .get_class($param).' ] => Array', FALSE);

        foreach (get_object_vars($param) as $key) {

            my_debug($key);

        }

    }

    if (is_array($param)) {

        my_print_r($param);

    }

}

function my_class($name = NULL) {

    $class = new ReflectionClass($name);

    my_print_r(Reflection::export($class));

}

function pre($param, $bool = TRUE) {

    if (!ini_get('xdebug.default_enable') || !$bool) {

        echo "<pre>".$param ."</pre>\n";

    }else {

        echo $param;

    }

}

To use the native MySQL ENUM type in Symfony and Doctrine you will have to update your "project/config/databases.yml" and add the "use_native_enum" directive under "attributes" i.e:

How to install YUM, Zend Optimizer, eAccelerator and APC

Iman — Wed, 12 Aug 2009 14:54:45 +0000

Recently a friend had difficulty installing Alternative PHP Cache (APC) and upload progress for his Drupal CMS on Debian VPS. Therefore I tought of sharing this post about how to setup and run your virtual private server with most useful PHP packages.

I would assume you have a Debian VPS, CentOs or Ubuntu and you would like to install APC, Zend Optimizer and eAccelerator for the best PHP performances or if they are required by some third party applications.

I normally like to install everything on Debian, CentOs or Ubuntu using the yum (Yellow dog Updater, Modified) package manger to make sure that updates for all applications are uniform and its easy to do, easy to search for available packages and easier to type instead of apt-get.
