Php Solutions
Solution 1 - Php
function limit_text($text, $limit) {
if (str_word_count($text, 0) > $limit) {
$words = str_word_count($text, 2);
$pos = array_keys($words);
$text = substr($text, 0, $pos[$limit]) . '...';
}
return $text;
}
echo limit_text('Hello here is a long sentence that will be truncated by the', 5);
Outputs:
Hello here is a long ...
Solution 2 - Php
Change the number 3 to the number 20 below to get the first 20 words, or pass it as parameter. The following demonstrates how to get the first 3 words: (so change the 3 to 20 to change the default value):
function first3words($s, $limit=3) {
return preg_replace('/((\w+\W*){'.($limit-1).'}(\w+))(.*)/', '${1}', $s);
}
var_dump(first3words("hello yes, world wah ha ha")); # => "hello yes, world"
var_dump(first3words("hello yes,world wah ha ha")); # => "hello yes,world"
var_dump(first3words("hello yes world wah ha ha")); # => "hello yes world"
var_dump(first3words("hello yes world")); # => "hello yes world"
var_dump(first3words("hello yes world.")); # => "hello yes world"
var_dump(first3words("hello yes")); # => "hello yes"
var_dump(first3words("hello")); # => "hello"
var_dump(first3words("a")); # => "a"
var_dump(first3words("")); # => ""

#To Nearest Space
Truncates to nearest preceding space of target character. Demo
$strThe string to be truncated$charsThe amount of characters to be stripped, can be overridden by$to_space$to_spacebooleanfor whether or not to truncate from space near$charslimit
Function
function truncateString($str, $chars, $to_space, $replacement="...") {
if($chars > strlen($str)) return $str;
$str = substr($str, 0, $chars);
$space_pos = strrpos($str, " ");
if($to_space && $space_pos >= 0)
$str = substr($str, 0, strrpos($str, " "));
return($str . $replacement);
}
Sample
<?php
$str = "this is a string that is just some text for you to test with";
print(truncateString($str, 20, false) . "\n");
print(truncateString($str, 22, false) . "\n");
print(truncateString($str, 24, true) . "\n");
print(truncateString($str, 26, true, " :)") . "\n");
print(truncateString($str, 28, true, "--") . "\n");
?>
#Output
this is a string tha...
this is a string that ...
this is a string that...

this is a string that is--
Solution 4 - Php
use explode() .
Example from the docs.
// Example 1
$pizza = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
echo $pieces[0]; // piece1
echo $pieces[1]; // piece2
note that explode has a limit function. So you could do something like
$message = implode(" ", explode(" ", $long_message, 20));
Solution 5 - Php
Try regex.
You need something that would match 20 words (or 20 word boundaries).
So (my regex is terrible so correct me if this isn't accurate):
/(\w+\b){20}/
And here are some examples of regex in php.

Simple and fully equiped truncate() method:
function truncate($string, $width, $etc = ' ..')
{
$wrapped = explode('$trun$', wordwrap($string, $width, '$trun$', false), 2);
return $wrapped[0] . (isset($wrapped[1]) ? $etc : '');
}

Its not my own creation, its a modification of previous posts. credits goes to karim79.
function limit_text($text, $limit) {
$strings = $text;
if (strlen($text) > $limit) {
$words = str_word_count($text, 2);
$pos = array_keys($words);
if(sizeof($pos) >$limit)
{
$text = substr($text, 0, $pos[$limit]) . '...';
}
return $text;
}
return $text;
}
Solution 8 - Php
Split the string (into an array) by <space>, and then take the first 20 elements of that array.

Solution 10 - Php
With triple dots:
function limitWords($text, $limit) {
$word_arr = explode(" ", $text);
if (count($word_arr) > $limit) {
$words = implode(" ", array_slice($word_arr , 0, $limit) ) . ' ...';
return $words;
}
return $text;
}
Solution 11 - Php
If you code on Laravel just use Illuminate\Support\Str
here is example
Str::words($category->publication->title, env('WORDS_COUNT_HOME'), '...')
Hope this was helpful.
Solution 12 - Php
Something like this could probably do the trick:
<?php
$words = implode(' ', array_slice(split($input, ' ', 21), 0, 20));
Solution 13 - Php
use PHP tokenizer function strtok() in a loop.
$token = strtok($string, " "); // we assume that words are separated by sapce or tab
$i = 0;
$first20Words = '';
while ($token !== false && $i < 20) {
$first20Words .= $token;
$token = strtok(" ");
$i++;
}
echo $first20Words;
Solution 14 - Php
based on 動靜能量's answer:
function truncate_words($string,$words=20) {
return preg_replace('/((\w+\W*){'.($words-1).'}(\w+))(.*)/', '${1}', $string);
}
or
function truncate_words_with_ellipsis($string,$words=20,$ellipsis=' ...') {
$new = preg_replace('/((\w+\W*){'.($words-1).'}(\w+))(.*)/', '${1}', $string);
if($new != $string){
return $new.$ellipsis;
}else{
return $string;
}
}
Solution 15 - Php
This worked me for UNICODE (UTF8) sentences too:
function myUTF8truncate($string, $width){
if (mb_str_word_count($string) > $width) {
$string= preg_replace('/((\w+\W*|| [\p{L}]+\W*){'.($width-1).'}(\w+))(.*)/', '${1}', $string);
}
return $string;
}
Solution 16 - Php
Try below code,
$text = implode(' ', array_slice(explode(' ', $text), 0, 32))
echo $text;
Solution 17 - Php
Here is what I have implemented.
function summaryMode($text, $limit, $link) {
if (str_word_count($text, 0) > $limit) {
$numwords = str_word_count($text, 2);
$pos = array_keys($numwords);
$text = substr($text, 0, $pos[$limit]).'... <a href="'.$link.'">Read More</a>';
}
return $text;
}
As you can see it is based off karim79's answer, all that needed changing was that the if statement also needed to check against words not characters.
I also added a link to main function for convenience. So far it hsa worked flawlessly. Thanks to the original solution provider.
Solution 18 - Php
Here's one I use:
$truncate = function( $str, $length ) {
if( strlen( $str ) > $length && false !== strpos( $str, ' ' ) ) {
$str = preg_split( '/ [^ ]*$/', substr( $str, 0, $length ));
return htmlspecialchars($str[0]) . '…';
} else {
return htmlspecialchars($str);
}
};
return $truncate( $myStr, 50 );

Another solution :)
$aContent = explode(' ', $cContent);
$cContent = '';
$nCount = count($aContent);
for($nI = 0; ($nI < 20 && $nI < $nCount); $nI++) {
$cContent .= $aContent[$nI] . ' ';
}
trim($cContent, ' ');
echo '<p>' . $cContent . '</p>';

To limit words, am using the following little code :
$string = "hello world ! I love chocolate.";
$explode = array_slice(explode(' ', $string), 0, 4);
$implode = implode(" ",$explode);
echo $implode;
$implot will give : hello world ! I
Solution 21 - Php
function getShortString($string,$wordCount,$etc = true)
{
$expString = explode(' ',$string);
$wordsInString = count($expString);
if($wordsInString >= $wordCount )
{
$shortText = '';
for($i=0; $i < $wordCount-1; $i++)
{
$shortText .= $expString[$i].' ';
}
return $etc ? $shortText.='...' : $shortText;
}
else return $string;
}
Solution 22 - Php
Lets assume we have the string variables $string, $start, and $limit we can borrow 3 or 4 functions from PHP to achieve this. They are:
-
script_tags() PHP function to remove the unnecessary HTML and PHP tags (if there are any). This wont be necessary, if there are no HTML or PHP tags.
-
explode() to split the $string into an array
-
array_splice() to specify the number of words and where it'll start from. It'll be controlled by vallues assigned to our $start and $limit variables.
-
and finally, implode() to join the array elements into your truncated string..
function truncateString($string, $start, $limit){ $stripped_string =strip_tags($string); // if there are HTML or PHP tags $string_array =explode(' ',$stripped_string); $truncated_array = array_splice($string_array,$start,$limit); $truncated_string=implode(' ',$truncated_array); return $truncated_string; }
It's that simple..
I hope this was helpful.
Solution 23 - Php
function limitText($string,$limit){
if(strlen($string) > $limit){
$string = substr($string, 0,$limit) . "...";
}
return $string;
}
this will return 20 words. I hope it will help
Solution 24 - Php
I made my function:
function summery($text, $limit) {
$words=preg_split('/\s+/', $text);
$count=count(preg_split('/\s+/', $text));
if ($count > $limit) {
$text=NULL;
for($i=0;$i<$limit;$i++)
$text.=$words[$i].' ';
$text.='...';
}
return $text;
}
Solution 25 - Php
$text='some text';
$len=strlen($text);
$limit=500;
// char
if($len>$limit){
$text=substr($text,0,$limit);
$words=explode(" ", $text);
$wcount=count($words);
$ll=strlen($words[$wcount]);
$text=substr($text,0,($limit-$ll+1)).'...';
}
Solution 26 - Php
function wordLimit($str, $limit) {
$arr = explode(' ', $str);
if(count($arr) <= $limit){
return $str;
}
$result = '';
for($i = 0; $i < $limit; $i++){
$result .= $arr[$i].' ';
}
return trim($result);
}
echo wordLimit('Hello Word', 1); // Hello
echo wordLimit('Hello Word', 2); // Hello Word
echo wordLimit('Hello Word', 3); // Hello Word
echo wordLimit('Hello Word', 0); // ''
Solution 27 - Php
Truncate the text surrounding a specific set of keywords.
The goal is to be able to convert this:
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna liqua. Ut enim ad minim veniam.
Into this:
...consectetur adipisicing elit, sed do eiusmod tempor...
Which is a very common situation when displaying search results, excerpts, etc.
I've posted a solution to that specific casuistic in this thread, hoping that it would be helpful for people landing here, too.

what about
chunk_split($str,20);
Entry in the [PHP Manual][1]

Solution 29 - Php
function limit_word($start,$limit,$text){
$limit=$limit-1;
$stripped_string =strip_tags($text);
$string_array =explode(' ',$stripped_string);
if(count($string_array)>$limit){
$truncated_array = array_splice($string_array,$start,$limit);
$text=implode(' ',$truncated_array).'...';
return($text);
}
else{return($text);}
