character_limiter

[vikas1111]

Hi all,
I want to print content of post but limited portion and after that i show a link “Read More” in end so that it leads to full post detail. But when i use substr() func and use 200 character it prints well but i need to print or need to end substring with full word

example:

Default:
This is my post and when it mak…

I need:
This is my post and when it makes…

I know there is some function in php but i really dont remember.

thanks in advance:

This is one solution i got after little bit of Googling. I am looking for the function which can replace bellow lines of code.

$position=14; // Define how many characters you want to display.
 
$message="gg rier j ajajjawer wjrwj rejwjre wjrwjre jwejr"; 
$post = substr($message,$position,1); // Find what is the last character displaying. We find it by getting only last one character from your display message. 
 
if($post !=" "){ // In this step, if last character is not " "(space) do this step . 
 
// Find until we found that last character is " "(space) 
// by $position+1 (14+1=15, 15+1=16 until we found " "(space) that mean character 20) 
while($post !=" "){
$i=1;
$position=$position+$i; 
 
$message="gg rier j ajajjawer wjrwj rejwjre wjrwjre jwejr"; 
$post = substr($message,$position,1); 
}
 
}
 
$post = substr($message,0,$position); // Display your message
echo $post;
echo "...";

wouldn't it be easier to look for the first space after a specified length/offset?

// using a 50 chars minimum length
$cut = strpos($text, ' ', 50);
// now using $cut in substr()

Hi Dormilich,

Thanks for reply. Yes its a good idea it works.

Kind Regards

Wouldn't it be better to cut the text of before reaching the limit?

$words = explode(" ", substr($post, 50));
array_pop($words);
echo implode(" ", $words);
 

I use this in a page where the text must not exceed the limit.

it would be also possible to cut at 50 (or whatever value) chars and use strrpos() to find the last space.

@Dormilich
Good point, and that might even be more efficient then my array method.
I'll have to look into that. Thanks! :-)
