Sometimes code needs you to generate PHP variables on the fly. This can mostly be avoided but if you want to it's very easy.
To create a dynamic variable you naturally need to start with a string to name the variable. You can get this by generating a number with a for loop, reading it in from a database or whichever input you're getting it from. As you know a variable name cannot start with certain characters and mainly needs to start with a letter (very basic explanation).
So straight to the code. We will do a simple example of generating a variable with a dynamic name.
//this will loop ten times starting with 0 and ending with 4
for ($i = 0; $i < 5; $i++){
$stringVariableName = 'myVar'.$i;
$$stringVariableName = $i;
}
This will generate the following php code:
$myVar0 = 0;
$myVar1 = 1;
$myVar2 = 2;
$myVar3 = 3;
$myVar4 = 4;
PLEASE NOTE: You cannot declare the variable $this as it is one of the reserved words in PHP.
