Trim a string up to character limit without word cut in PHP

Lots of times when you're developing a site, you'll want to have a snippet of text in one place. PHP doesn't really have a good way of doing this because different languages have different definitions of "words", and a space-character is not always the delimiter between words, as it is in most Latin-based languages.

But for those of us speaking languages that stick spaces between words, clients will often ask us to "just show the first 10 words" here or there. So here's a handy PHP function to do just that.

This function can be used to trim a long string up to a given character limit/count without the last word not being cut half.



function trim_me($content, $limit){

$content = substr($content, 0,$limit);
 
$wordlimit = 1000;

$content = explode(' ',$content);

for($i=0; $i<$wordlimit; $i++) $summary[$i] = $content[$i];

$summary = implode(' ', $summary).'...';

return $summary;

}

?>

Sample Usage:

trim_me($sample_string,10);

Could not find the file flash.ocx - FIX

Some third party screen savers are designed to make use of the flash player software when running.

Which results in the errors such as;
  • “Could not find the file flash.ocx”
  • cant find file flash.ocx
  • cannot find file flash ocx
To fix this simple problem,

1. Browse to the C:\Windows\System32\Macromed\Flash folder.
2. Locate the flash9.ocx or flash10.ocx or similar flash[*].ocx file and make a copy of that file.
3. Rename the new copied file to flash.ocx
Voila Done !!!
