Remove the First 4 Characters of a string in PHP

In this tutorial, we are going to learn about how to remove the first 4 characters of a string in PHP.

Consider, we have a following string:

$place="paris";

Now, we want to remove the first 4 characters pari from the above string.

Note: In PHP, strings are the sequence of characters that can be accessed by using its character index, where the first character index is 0, second character is 1 and the first character index is -1, etc.

Removing the first 4 characters

To remove the first 4 characters of the string, we can use the built-in substr() function by passing $string , 4 as a arguments.So, it returns a new string by removing the first 4 characters from it.

The substr() function accepts three arguments, the first one is string, the second is start position, third is length (optional).

Here is an example :

$place="paris";
$result = substr($place, 4);
echo $result;

Output:

"s"

In the example above, we have passed 4 as a second argument to the substr() function. so it begins the extraction at index 4, and extract the rest of a string.

Note: The substr() function doesn’t mutate the original string, instead of it creates a new string with the modified data.
