How to get the last 7 characters of a string in PHP

To get the last 7 characters of a string in PHP, we can use the built-in substr() function by passing the first argument as a string and second argument -7.So, it returns the last seven characters of a string.

Note: -7 is the number of characters we need to extract from the end position of a string.

Here is an example

$string = "you are learningphp";
$lastseven = substr($string, -7);

echo  $lastseven;

Output:

ningphp

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

Similarly, you can also get last n characters from a string by changing the second argument.

$string = "you are learningphp";
$lasttwo = substr($string, -2);

echo  $lasttwo;
