Whenever it comes to web development, many developers want tips to improve their websites. Web development in PHP is pretty easy for newbies. All you need is PHP tutorials for beginners and the easiest way to optimize a PHP website.
PHP is one of the most loved and widely used languages that developers love to build their websites in. The best part of PHP development is that developers can find a guide for PHP developers and the best PHP tips and tricks on the official PHP site. Another advantage of PHP is that, as a PHP developer, you can find good frameworks and CMSs to work on. Many people tend to ask, ‘How can I improve my PHP code?’ The answer to this lies in practice and being capable of building your own confidence in creating a project and releasing it. You can also learn PHP by building web applications.
Key Takeaways:
The error reporting feature, an important feature in a PHP website, is one of the best Useful PHP tricks for Developers. The best thing to cope with errors is to set the system to display errors. To set the settings, you have to alter the php.ini file when you develop your site. Include these two lines at the beginning.
error_reporting ( E_ALL ) ; ini_set ( 'display_errors' , 1 ) ;
The following code helps you to see both types of errors, whether the fatal errors that produce the dreaded white screen or warnings and notices that may be bugs to fix.
Security holes are the biggest cause of the bad reputation of PHP, but PHP tips for website development are here.
There are many ways to avoid SQL injection, but the simplest one is to escape any variable that we will use in the database. The code should look like this:
$query_result = mysql_query ( "SELECT * FROM WHERE Ex_table ex_field = \" " . mysql_real_escape_string( $ ex_field ) . " \ " " ) ;
PHP developers prefer using include() or require() to call other files, libraries, or classes, but using include_once () and require_once () are PHP tricks for web developers. Both functions have the same functionality, but the advantage is that they prevent files, classes, or loaded libraries from being loaded again, which causes duplication and undesired states in the code.
The best PHP tips and tricks for good performance are to use ternary operators as an alternative to simple IF constructions. For instance:
$age = ( !empty ( $ _ GET [ 'age ] ) ? $ _ GET [ 'age' ] : 58 ) ;
This would help your code to get lighter and can be nested without problems.
This is 2017, and the technology that we are using is advanced now; this is the time for PHP7. A high time to retire your MySQL database and start using PDO. A PHP extension that helps you connect to different database managers.
A very important feature of the MySQL driver is MySQL Connector/Python, which supports almost all features provided by MySQL version 5.7. Designed specifically for MySQL, MySQL Connector/Python lets you translate the parameter’s value between Python and MySQL data types. Obviously, PHP works with other databases too. As a PHP web developer, this tip is one of the best PHP tips and tricks for me for website development with PHP. The code to connect with databases is:
try {
$conn = new PDO ( "mysql: host = localhost; dbname = database ' , $ user , $ pass ) ;
$conn -> setAttribute ( PDO :: ATTR_ERRMODE , PDO :: ERRMODE_EXCEPTION ) ;
} Catch ( PDOException $e ) {
Echo "ERROR:" . $e -> getMessage ( ) ;
}
Are you a speedy programmer who can type code fast?
Well, here’s a trick for you! Just use single quotes (“) rather than double quotes (” “). Trust me! It saves you a lot of time and improves the performance of your server. Best PHP tips and tricks code! ha?
The file .htaccess is the best yet simple way to make the URLs simpler for the human eye as well as for SEO. A hidden file that serves a lot with Apache directives. The services that this file provides are performing redirection and clean URLs do not cease to be redirected to after all. One of the best tips and tricks for PHP-based application improvements.
RewriteEngine On RewriteRule ^ ( [ a - zA - Z0 - 9 ] + ) $ index . Php? Page = $ 1
This code is a lifesaver for many PHP developers who can prevent horrible URLs and make it sleek and simple, phew!
One of the PHP tricks for web developers is to understand what the isset() function does. Make sure that you know when the isset() function returns false and when it returns true. This function returns True if the variable is not NULL. Yes, you read it correctly: not NULL.
Just like so, if NULL can be a valid value of the variable, we surely have a problem, sir!
$foo = null ; if ( isset( $ foo ) ) // returns false And the solution is: Use get_defined_vars( ); $foo = NULL ; $vars = get_defined_vars( ); if ( array_key_exists ( 'foo' , $ vars ) ) // returns True
The useful PHP trick for Developers: use Switch instead of crazy Ifs. Advantage? The code will execute faster, thus performance is increased. The usage of Switch statements allows you to go beyond the use of if-else if-else chains.
switch ($color ) {
case 'white' :
echo "The color is White" ;
break ;
case 'blue' :
echo "The color is Blue" ;
break ;
case 'green' :
echo "The color is Green" ;
break ;
case 'black' :
echo "Color is black" ;
break ;
}
The method to retrieve a file from another server is to use the powerful way cURL, instead of using file_get_contents() function which is easy to use but come on, it’s like having death on your computer. The following code is an example of using cURL:
$c = curl_init ( ) ; curl_setopt ( $c , CURLOPT_URL , $URL ) ; curl_setopt ( $c , CURLOPT_TIMEOUT , 15 ) ; curl_setopt ( $c , CURLOPT_RETURNTRANSFER , true ) ; $content = curl_exec ( $c ) ; $status = curl_getinfo ( $c , CURLINFO_HTTP_CODE ) ; curl_close ( $c ) ;
Often developers ask Tips to improve the website; well, here is one: PHP is always on your side, and it encrypts your passwords for you. I am talking about PHP 5.5+ versions. Just store the passwords in your database as.
$enc_pass = password_hash ( $submitted_pass , PASSWORD_DEFAULT ) ;
To check if the password is correct or not:
if ( password_verify ( $submitted_pass , $stored_pass ) )
{
// User successfully authenticated
}
Typically used for web development, PHP is the server-side scripting language. Invented in 1994 by Rasmus Lerdorf, PHP has done a remarkable job in the technology-based world and made the whole work of web development extremely easy for developers.
There’s little doubt that working knowledge of PHP is too important to sustain in today’s cut-throat technology sphere. Here are the 5 advanced PHP tips to learn PHP programming.
OOP is the basic requirement of PHP that every developer should know. PHP follows object-oriented programming, and therefore items and programs link things together for developing a program. Using OOP approaches, you can skip the replication of code and can complete the code in a much simpler way. Objects are demarcated under the programs, and then you can reuse them again and again throughout the program. OOP is faster, easier to correct, and uses slightly fewer server resources, less code, and a quicker loading process to evade long events. Going with OOP, you can make your coding style more effective and simpler.
PHP language is extremely easy to learn and adjustable for a developer to develop the best websites. Using the built-in advanced PHP techniques, you will get the concealed benefits which are very valuable throughout the coding process. If you are doing custom PHP development or web development, the need for displays and functions is very significant. For example, if you want to count the numbers, then you can use count(), and like that, PHP has a number of built-in functions that are very beneficial for making the coding procedure easy and quick.
The first thing prior to starting any PHP project is that you should use mysl_real_escape_string() for all the database. Doing this will help you keep all the strings safe from any kind of unwelcome threats that may have some malicious code. This should be your first step to protect your database. The other vital thing is that never use $_REQUEST – instead, go with POST or GET strings for submitting the data into the database query.
A good programmer is well aware of the difference between these two. The GET method displays the address in the URL and gives simpler ways for the hacker to totally hack your entire project. Going with POST, you can face a secure journey throughout your coding and development procedure.
Before you explore the real platform, just stop for a few minutes and make a rough draft of your whole code. This will give you better comprehension and will clear your thoughts for developing the website. Also, you will discover the main glitches that you will face in the future journey of coding.
