What php string function should i use?

[yyx748]

Original text: "Hello World"

 

==CASE 1==

Turning extra alphabets after position 7 to "..."

output: "Hello W..."

 

==CASE 2==

Showing WORDS that comes before position 7.

output: "Hello..."

 

Could someone tell me what functions do i use for both cases?

substr

I use the following:

 

<?php

$count = 10;
$words = "blah blah blah";
$shortwords = substr($words,0,$count);

echo "$shortwords...";

?>

Giving the output:

 

blah blah ...

 

Obviously change $count to set the character limit.

$word = "Hello world";

$word = explode (" ", $word);

if ( count($word) > 0)
{
   echo $word[0] . '...';
}
