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.
-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;
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;
