In this tutorial, we are going to learn about how to remove the last character of a string in PHP.
Consider, we have a following string:
Now, we want to remove the last character
s from the above string.
To remove the last character of the string, we can use the built-in
substr() function in PHP.
substr() function accepts three arguments, the first one is
string, the second is start position, third is length.
Here is an example, that removes the last character
s from the
$place="paris"; $result = substr($place, 0, -1); echo $result;
In the example above, we have passed
0, -1 as second and third arguments to the
substr() function. so it begins the extraction at index
0 and extracts before the last character of a string.
lengthis given negative then characters are removed from the end of a string.
substr() function doesn’t mutate the original string.
