Tips for improvingPHP code

Problem 1 Not using PHP built-in function

• Sometimes we try to solve the small problem with
  our own function instead of a built-in PHP
  function that provides the functionality.
• SolutionPHP provides many useful functions that
  remove the need to refresh the wheel, and will
  often complete the work much better than anything
  typed by a standard program. Therefore, if you
  are experiencing the need to write complex tasks
  that you think may already exist, it is best to
  search the Internet (and PHP scripts in
  particular) before you start writing your code.

Problem 2 Not creating functions

• Not creating functions is a typical problem for
  developers mainly for beginners. The problem
  stems from the fact that a programmer can write
  multiple lines of PHP scripts without having to
  encrypt parts of the code into tasks. This is
  problematic because it is difficult to understand
  what the code actually does without going deeper
  into it, and the developer may repeat himself
  unintentionally.
• Solution
• Dividing the functions into small individual
  functions is a good solution to this problem.

Problem 3 Code Duplication

• If you are writing the same code more than one or
  two times then there will be something wrong with
  the code. In this way you are violating the
  important rule of modern code writing Do not
  Repeat Yourself (DRY). This is important because
  if the code is finished and one code is written
  more than one time and after that, if there need
  to make changes, then you have to make more
  efforts to make changes in all the places.
• Solution
• Wrap the code in a function is a good way to
  avoid duplication. Then the function can be
  called whenever needed.

Problem 4 Vague names for functions and
variables

• Another problem that seems to exist even within
  the experienced system is that of the fixed and
  unambiguous words that do not change variables
  and function. For example, a job name like
  "doSomething" is not very clear. The problem may
  be due to a number of reasons a lack of
  awareness, laziness, or the result of an activity
  that was written to perform a particular action,
  but which ended up taking another action instead.
  It creates the problem of readability of the code
  and makes it difficult in maintaining and making
  changes in the code.
• SolutionThe solution is to assign an
  illustrative word that contains 2 to 3 words or
  more to function and variable names.
