How to Add or Remove characters from a string

Hello Developers,

In this demonstration, you will find the usage of substr() in PHP. 


The substr() function requires three parameters. These are given below:


substr(string $string, int $offset, ?int $length = null): string


Returns the portion of string specified by the offset and length parameters. First, we have to open up a code editor and paste the below code to run the file to see the output. We can see two examples from the below code:



$name="John Doe";

//if length is negative it starts removing from the end
$result = substr($name,0,-3);
echo $result; echo '<br>';

//if length is positive it starts removing from the begining
$result = substr($name, 0, 6);
echo $result;

I hope this might help you in the journey of development.
