PHP Developer in India Lists 8 Commonly Used Still Less Known PHP Functions

Successfully completing a project for PHP development would mean that the PHP developer in India is going to add a combination of functions to ensure proper development of the product. While there are many different functions available in PHP development it is of course difficult to remember all of them. Hence here we have a list of some PHP functions which are commonly used by PHP developers but are less mentioned online :

1) Argument with inconsistent numbers : It is a common practice for a PHP developer in India to use optional arguments to define functions but few would be aware that they can even define innumerable number of function arguments using func_get_args(). It has the ability to work with any number of numbers.

2) Find Files using Glob() : Are you familiar with this term, it's ok if you are not familiar with it because many terms in PHP development are such that it is difficult to remember their functions. It is in fact difficult to even guess what would Glob() mean because the function is not self representative. It is a function which can be used by a PHP developer in India to search files using patterns. Even multiple files can be searched using this function. Use realpath() function to find the complete path to the file.

3) Memory Usage Update : Monitoring the memory usage on the script is very important to ensure that the application does not become all that heavy as heavy applications can affect the site popularity. If in case the application is heavy then the PHP developer in India can make relevant changes to the script. Current update on memory can be checked using the memory_get_usage() function and memory_get_peak_usage() function should be used to check highest memory consumption at any time.

4) CPU Usage Update : This is also as important as memory usage update because often people have limited CPU space and so find it difficult to run heavy applications. If a PHP developer is working on a platform other than Windows then they can use getrusage() function which will display the CPU usage in 'system time' and 'user time' values.

5) Magic Constants : These help a PHP developer in India to fetch directory path, class name, current line number, function name, file path, namespace and method name.

6) Unique ID Generation : Often a PHP application requires unique ID generation, what would you do when you have to do this, most of the PHP developers use md5() function though it is not meant for this. However the ideal practice for doing this is to use uniqid() function.

7) Serialization : This function is used by developers when the application needs that they store complex variable in database or text file. A PHP developer in India can use two different functions to do this a) serialize() and unserialize() or b) json_encode() and json_decode() functions.

8) String Compression : Zip and RAR are commonly used compression archives but for PHP a developer can use gzcompress() and gzuncompress() functions to compress long strings. Using these functions developers can reduce the size of code by atleast 50%.
