String Length (Limit and reveal)

[wispas]

I currently have a script that will limit the amount of words string. instead i want it to display all of the text upon clicking a read more link at the end. is this possible with php?

[wispas]

<?php

  // Limit $summary to how many characters?

  $limit = 57;

$summary = <<< summary

Text Text Text Text Text Text Text Text Text Text Text Text

Text Text Text Text Text Text Text Text Text

Text Text Text Text Text Text Text Text Text Text

Text Text Text Text Text Text Text Text Text

Text Text Text Text Text Text Text Text Text Text

Text Text Text Text Text Text Text Text Text Text

summary;

 

  if (strlen($summary) > $limit)

      $summary = substr($summary, 0, strrpos(substr($summary, 0, $limit), ' ')) . '...';

      echo $summary;

 

function bigone() {

$limit = 100;

echo $summary;

}

 

?>

You can use a bit of javascript (http://llizard.etherwork.net/cwc/showhide.html) along with PHP's substr() function (http://php.net/manual/en/function.substr.php).
