PHP File Permissions
If you are having errors when trying to get this code to run, check that you have granted your PHP file access to write information to the hard drive.

PHP Write to File - fwrite()
The fwrite() function is used to write to a file.

The first parameter of fwrite() contains the name of the file to write to and the second parameter is the string to be written.

The example below writes a couple of names into a new file called "newfile.txt":

#php #content #scappy

PHP for Loop:
The for loop - Loops through a block of code a specified number of times.

The PHP for Loop
The for loop is used when you know in advance how many times the script should run.

Parameters:
init counter: Initialize the loop counter value
test counter: Evaluated for each loop iteration. If it evaluates to TRUE, the loop continues. If it evaluates to FALSE, the loop ends.
increment counter: Increases the loop counter value
Examples
The example in image; displays the numbers from 0 to 10:

Example Explained
$x = 0; - Initialize the loop counter ($x), and set the start value to 0
$x <= 10; - Continue the loop as long as $x is less than or equal to 10
$x++ - Increase the loop counter value by 1 for each iteration

The PHP switch Statement
Use the switch statement to select one of many blocks of code to be executed

This is how it works: First we have a single expression n (most often a variable), that is evaluated once. The value of the expression is then compared with the values for each case in the structure. If there is a match, the block of code associated with that case is executed. Use break to prevent the code from running into the next case automatically. The default statement is used if no match is found.

Create a PHP Constant :-

Example
Create a constant with a case-sensitive name:

#scappy #php #code #content

PHP Variables
A variable can have a short name (like x and y) or a more descriptive name (age, carname, total_volume).

Rules for PHP variables:

A variable starts with the $ sign, followed by the name of the variable
A variable name must start with a letter or the underscore character
A variable name cannot start with a number
A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
Variable names are case-sensitive ($age and $AGE are two different variables)
