How to get the last char of a string in PHP? - php

Question

I need to get the last character of a string.
Say I have "testers" as input string and I want the result to be "s". how can I do that in PHP?

Answer 1

substr("testers", -1); // returns "s"
Or, for multibyte strings :
mb_substr("multibyte string…", -1); // returns "…"

Answer 2

substr($string, -1)

Answer 3

Or by direct string access:
$string[strlen($string)-1];
Note that this doesn't work for multibyte strings. If you need to work with multibyte string, consider using the mb_* string family of functions.
As of PHP 7.1.0 negative numeric indices are also supported, e.g just $string[-1];

Answer 4

From PHP 7.1 you can do this (Accepted rfc for negative string offsets):
<?php
$silly = 'Mary had a little lamb';
echo $silly[-20];
echo $silly{-6};
echo $silly[-3];
echo $silly[-15];
echo $silly[-13];
echo $silly[-1];
echo $silly[-4];
echo $silly{-10};
echo $silly[-4];
echo $silly[-8];
echo $silly{3}; // <-- this will be deprecated in PHP 7.4
die();
I'll let you guess the output.
Also, I added this to xenonite's performance code with these results:
substr() took 7.0334868431091seconds
array access took 2.3111131191254seconds
Direct string access (negative string offsets) took 1.7971360683441seconds

Answer 5

As of PHP 7.1.0, negative string offsets are also supported.
So, if you keep up with the times, you can access the last character in the string like this:
$str[-1]

At the request of a #mickmackusa, I supplement my answer with possible ways of application:
<?php
$str='abcdef';
var_dump($str[-2]); // => string(1) "e"
$str[-3]='.';
var_dump($str); // => string(6) "abc.ef"
var_dump(isset($str[-4])); // => bool(true)
var_dump(isset($str[-10])); // => bool(false)

Answer 6

I can't leave comments, but in regard to FastTrack's answer, also remember that the line ending may be only single character. I would suggest
substr(trim($string), -1)
EDIT: My code below was edited by someone, making it not do what I indicated. I have restored my original code and changed the wording to make it more clear.
trim (or rtrim) will remove all whitespace, so if you do need to check for a space, tab, or other whitespace, manually replace the various line endings first:
$order = array("\r\n", "\n", "\r");
$string = str_replace($order, '', $string);
$lastchar = substr($string, -1);

Answer 7

I'd advise to go for Gordon's solution as it is more performant than substr():
<?php
$string = 'abcdef';
$repetitions = 10000000;
echo "\n\n";
echo "----------------------------------\n";
echo $repetitions . " repetitions...\n";
echo "----------------------------------\n";
echo "\n\n";
$start = microtime(true);
for($i=0; $i<$repetitions; $i++)
$x = substr($string, -1);
echo "substr() took " . (microtime(true) - $start) . "seconds\n";
$start = microtime(true);
for($i=0; $i<$repetitions; $i++)
$x = $string[strlen($string)-1];
echo "array access took " . (microtime(true) - $start) . "seconds\n";
die();
outputs something like
----------------------------------
10000000 repetitions...
----------------------------------
substr() took 2.0285921096802seconds
array access took 1.7474739551544seconds

Answer 8

As of PHP 8 you can now use str_ends_with()
$string = 'testers';
if (\str_ends_with($string, 's') {
// yes
}

Answer 9

Remember, if you have a string which was read as a line from a text file using the fgets() function, you need to use substr($string, -3, 1) so that you get the actual character and not part of the CRLF (Carriage Return Line Feed).
I don't think the person who asked the question needed this, but for me, I was having trouble getting that last character from a string from a text file so I'm sure others will come across similar problems.

Answer 10

You can find last character using php many ways like substr() and mb_substr().
If you’re using multibyte character encodings like UTF-8, use mb_substr instead of substr
Here i can show you both example:
<?php
echo substr("testers", -1);
echo mb_substr("testers", -1);
?>

Answer 11

A string in different languages including C sharp and PHP is also considered an array of characters.
Knowing that in theory array operations should be faster than string ones you could do,
$foo = "bar";
$lastChar = strlen($foo) -1;
echo $foo[$lastChar];
$firstChar = 0;
echo $foo[$firstChar];
However, standard array functions like
count();
will not work on a string.

Answer 12

Use substr() with a negative number for the 2nd argument.$newstring = substr($string1, -1);

Answer 13

Siemano, get only php files from selected directory:
$dir = '/home/zetdoa/ftp/domeny/MY_DOMAIN/projekty/project';
$files = scandir($dir, 1);
foreach($files as $file){
$n = substr($file, -3);
if($n == 'php'){
echo $file.'<br />';
}
}
