how i can display only 2 phrase from sql [duplicate] - php

Question

Is there a way to trim a text string in PHP so it has a certain number of characters? For instance, if I had the string:
$string = "this is a string";
How could I trim it to say:
$newstring = "this is";
This is what I have so far, using chunk_split(), but it isn't working. Can anyone improve on my method?
function trimtext($text)
{
$newtext = chunk_split($text,15);
return $newtext;
}
I also looked at this question, but I don't really understand it.

Answer 1

if (strlen($yourString) > 15) // if you want...
{
$maxLength = 14;
$yourString = substr($yourString, 0, $maxLength);
}
will do the job.
Take a look here.

Answer 2

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').'...';

Answer 3

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;
}

Answer 4

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);
Would return:
This is a

Answer 5

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

Answer 6

You can use this
substr()
function to get substring

Answer 7

If you want to get a string with a certain number of characters you can use substr, i.e.
$newtext = substr($string,0,$length);
where $length is the given length of the new string.

Answer 8

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];

Answer 9

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 $text." ...";
}
Or if the text is coming from an editor and you want to strip out the HTML tags.
function truncate($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." ...";
}

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;
