Tag: PHP Development Notes
This posts was written in year 2006 on 20th May. In one of my server crash, I lost my posts, Today I got it recovered from Archive.org, and representing it again.
Today, I am going to write about array PHP functions, these functions allow you to interact with and manipulate arrays in various ways.
Arrays are essential for storing, managing, and operating on sets of variables.
What are Arrays?
This is very easy to tell but sometime it is really difficult to understand the dynamics of arrays, after functions, arrays are one of the greatest mechanism of programming to solve the problem of data maintenance and presentation.…
Optimization of database tables in mysql is a process which has to be carried out regularly to make your database in good health.
According to mysql manual,
OPTIMIZE TABLE should be used if you have deleted a large part of a table or if you have made many changes to a table with variable-length rows (tables that have VARCHAR, VARBINARY, BLOB, or TEXT columns). Deleted rows are maintained in a linked list and subsequent INSERT operations reuse old row positions. You can use OPTIMIZE TABLE to reclaim the unused space and to defragment the data file.
In this article you will learn how to install and configure the PHP/Java Bridge and how to use Java classes in PHP scripts in a demo application. To use the PHP/Java bridge, you should have knowledge of Java SE and the PHP5 core, as well as how they interact.
PHP 4 supported an extension for combining PHP with Java, but to combine PHP with Java in PHP 5 you should install the PHP/Java Bridge, which the website describes as:”… an implementation of a streaming, XML-based network protocol, which can be used to connect a native script engine, for example PHP, Scheme or Python, with a Java virtual machine.”

In this article, I am going to write about the functions using which you can get the information about php functions.
For a full list of PHP functions you can visit http://www.zend.com/phpfunc/
Using these functions you can query the stats/status of your functions, these functions are very useful in dynamic application creation.
For example, using func_get_arg and func_num_args functions you can simulate the function overloading in PHP.
Read a good example for http://www.dubi.org/php-function-overloading
Functions I will write in this article are :-
You want to how many functions are in your installation of PHP, just call this function, it will return an array of all php functions you can call.…
Some weeks ago I got an old PHP application to work with. I was asked to look for the potential problems and bottlenecks in the application. So I decide to use APD as a profiler for the application, after installing the APD on that server. I enabled profiler on one of the reportedly slow page.
That page was meant to be displayed and executed only if user is logged in and session variables are set. If we dont found user session then user was being redirected to Login page of the application.…
This question again struck me today, somebody just throw a simple question about EXPLAIN statement in MySQL and in hast I relate that to DESCRIBE. When that person cut the line of phone, I suddenly realize my mistake.
I am working with PHP and MySQL since last seven years then why this happen to me? This is because I am not using MySQL frequently, although it is the integral part of almost every application I am working on. I am fairly away from MySQL queries because I am using my factory classes or framework like cakephp which does not require me to write the SQL queries.…
PHP 5 is in the market since many years, but it still has to capture the market.
Why? Is it not efficient version of PHP language?
What are main reasons behind slow-adoption of PHP version 5.
I am compiling a list of reasons; you can also send me the reason why you have moved to PHP5 or why you are not able to do that?
I will write about that list in my coming articles.…
In this article I am going to write my experience with a work in which I was supposed to do file upload progress bar.
First of all I consider using APC then came to know about PECL extension uploadprogress
Unfortunately both were not possible for me as I have no control on the server on which it was supposed to run.
Tweaking with installed version of PHP or up gradation of PHP was also ruled out.
In India we have a word which is very common in use whenever someone is in a deadlock, the magic word is ‘Jugad’, if simply translated into English, it will mean ‘system’, but in contextual meaning it stands for ‘Smart Work’.…
