Get the last word of a string

Question

I have tried a few things to get a last part out I done this:

$string = \'Sim-only 500 | Internet 2500\';
preg_replace(\"Sim-Only ^([1-9]|[1-9][0-9]|[1-9][0-         


        

Answer 1

This should work for you:

$str = "fetch the last word from me";
$last_word_start = strrpos ( $str , " ") + 1;
$last_word_end = strlen($str) - 1;
$last_word = substr($str, $last_word_start, $last_word_end);

Answer 2

If you want to wrap the last word with a span:

<?php
/**
 * Wrap last word with span
 * @author: Elron
 * https://stackoverflow.com/questions/18612872/get-the-last-word-of-a-string
 */
function wrap_last_word($string) {
    // Breaks string to pieces
    $pieces = explode(" ", $string);

    // Modifies the last word
    $pieces[count($pieces)-1] = '<span class="is-last-word">' . $pieces[count($pieces)-1] . '</span>';

    // Returns the glued pieces
    return implode(" ", $pieces);
}

wrap_last_word('hello this is wrapped');
// returns this:
// hello this is <span class="is-last-word">wrapped</span>

Answer 3

It depends on what you try to do (it is hard to understand from your description) but to get the last word from a string you can do:

$split = explode(" ", $string);

echo $split[count($split)-1];

See How to obtain the last word of a string for more information.

If you're after the last word in a sentence, why not just do something like this?

$string = '​Sim-only 500 ​| Internet 2500';
$pieces = explode(' ', $string);
$last_word = array_pop($pieces);

echo $last_word;

I wouldn't recommend using regular expressions as it's unnecessary, unless you really want to for some reason.

$string = 'Retrieving the last word of a string using PHP.';
preg_match('/[^ ]*$/', $string, $results);
$last_word = $results[0]; // $last_word = PHP.

Using a substr() method would be better than both of these if resources/efficiency/overhead is a concern.

$string = 'Retrieving the last word of a string using PHP.';
$last_word_start = strrpos($string, ' ') + 1; // +1 so we don't include the space in our result
$last_word = substr($string, $last_word_start); // $last_word = PHP.

it is faster, although it really doesn't make that much of a difference on things like this. If you're constantly needing to know the last word on a 100,000 word string, you should probably be going about it in a different way.

Answer 5

The existing solutions all work fine, but I wanted a one-liner. explode() will split a sentence into words, but trying to pass it directly into array_pop() or end() gives a "Only variables should be passed by reference" notice. array_slice() to the rescue:

$string = 'Sim-only 500 | Internet 2500';
echo array_slice(explode(' ', $string), -1)[0];

Answer 6

Here is another way to get the last word from a string

$my_string = "fetch the last word from me";
 
// Explode the string into an array
$my_string = explode(" ", $my_string);

// target the last word with end() function 
$my_string = end($my_string);

echo $my_string;

Result me
