Function to skip strtolower() if variable contain "wikipedia.org"

[ArizonaJohn]

Hello,

 

My site allows users to enter URLs into a database.  I am using the code "$site = strtolower($site);" to make all of these URLs lower-case.

 

However, I just realized that Wikipedia URLs are case sensitive, so I would like to avoid using "$site = strtolower($site);" on Wikipedia URLs, all of which contain "wikipedia.org".

 

How could I write a function that will skip over the step "$site = strtolower($site);" if $site contains "wikipedia.org"?

 

Thanks in advance,

 

John

if (!strpos($site,'wikipedia.org')) {

  $site = strtolower($site);

}

 

so essentially it says if wikipedia.org is not found in the string to lower case the string.

if(strpos($site, 'wikipedia.org') === false)
{
     $site = strtolower($site);
}

if (!strpos($site,'wikipedia.org')) {

  $site = strtolower($site);

}

 

so essentially it says if wikipedia.org is not found in the string to lower case the string.

Try that with -

$site = 'WIKIPEDIA.ORG is all in caps!';

so use stripos instead. Or, if you do not have php5, use some good old fashioned regex:

 

if(!preg_match('~wikipedia\.org~i',$string)) {
  $string = strtolower($string);
}
