Shorten a text string in PHP

Solution:

if (strlen($yourString) > 15) // if you want...
{
    $maxLength = 14;
    $yourString = substr($yourString, 0, $maxLength);
}
Copy code

will do the job.

Solution:

substr cuts words in half. Also if word contains UTF8 characters, it misbehaves. So it would be better to use mb_substr:

$string = mb_substr('word word word word', 0, 10, 'utf8').'...';

Solution:

You didn't say the reason for this but think about what you want to achieve. Here is a function for shorten a string word by word with or without adding ellipses at the end:

function limitStrlen($input, $length, $ellipses = true, $strip_html = true) {
    //strip tags, if desired
    if ($strip_html) {
        $input = strip_tags($input);
    }

    //no need to trim, already shorter than trim length
    if (strlen($input) <= $length) {
        return $input;
    }

    //find last space within length
    $last_space = strrpos(substr($input, 0, $length), ' ');
    if($last_space !== false) {
        $trimmed_text = substr($input, 0, $last_space);
    } else {
        $trimmed_text = substr($input, 0, $length);
    }
    //add ellipses (...)
    if ($ellipses) {
        $trimmed_text .= '...';
    }

    return $trimmed_text;
}

Solution:

function trimtext($text, $start, $len)
{
    return substr($text, $start, $len);
}

You can call the function like this:

$string = trimtext("this is a string", 0, 10);
Copy code

Would return:

This is a

Solution:

let's you take a portion of string consisting of exactly as much characters as you need.

Solution:

You can use this

substr()

function to get substring

Solution:

If you want to get a string with a certain number of characters you can use substr, i.e.

$newtext = substr($string,0,$length); 
Copy code

where $length is the given length of the new string.

Solution:

If you want an abstract for the first 10 words (you can use html in $text, before script there is strip_tags) use this code:

preg_match('/^([^.!?\s]*[\.!?\s]+){0,10}/', strip_tags($text), $abstract);
echo $abstract[0];

Solution:

My function has some length to it, but I like to use it. I convert the string int to a Array.

function truncate($text, $limit){
    //Set Up
    $array = [];
    $count = -1;
    //Turning String into an Array
    $split_text = explode(" ", $text);
    //Loop for the length of words you want
    while($count < $limit - 1){
      $count++;
      $array[] = $split_text[$count];
    }
    //Converting Array back into a String
    $text = implode(" ", $array);

    return $text." ...";

  }
Copy code

Or if the text is coming from an editor and you want to strip out the HTML tags.

function truncate($text, $limit){
    //Set Up
    $array = [];
    $count = -1;
    $text = filter_var($text, FILTER_SANITIZE_STRING);

    //Turning String into an Array
    $split_text = preg_split('/\s+/', $text);
    //Loop for the length of words you want
    while($count < $limit){
      $count++;
      $array[] = $split_text[$count];
    }

    //Converting Array back into a String
    $text = implode(" ", $array);

    return $text." ...";

  }
Copy code

Solution:

With elipsis (...) only if longer - and taking care of special language-specific characters:

mb_strlen($text,'UTF-8') > 60 ? mb_substr($text, 0, 60,'UTF-8') . "…" : $text;
