[SOLVED] string display length

[shadiadiph]

mm not sure how to explain this but here goes.

 

Say I have a string $subject which could be 5 or 100 characters in length but i never want to display more than the first 30 characters of it how would i do this?

[Ken2k7]

substr

[nblasgen]

define('MAX_SIZE', 30);

if (strlen($subject) > MAX_SIZE)

  {

    echo substr($subject, 0, MAX_SIZE - 3) . '...';

  }

  else

  {

    echo $subject;

  }

[Ken2k7]

Why MAX_SIZE - 3?

[DarkSuperHero]

he probably did MAX_SIZE - 3 so that including the '...' it would not exceed the total number of desired characters... just a guess though...

thank you

 

I had to use to get it to display the first 36 characters of the string

 

$subject2   = substr($subject,0,36);
