check if words in a string are uppercase

[nielskg]

Hi,

I need a short piece of code that checks if there are words in a string that are totally uppercase, and if so that that word get's turned to lowercase...

Any ideas?

How about making a regular-expression to match chars only in uppercase. Something like this :

"(^| )([A-Z]+)( |$)"

.. matches beginning or a space, then one of more upcased chars between A and Z and then either end of string or a space. Just an idea - you need to code the replacing yourself! s

I hope this is what you mean.

$string = "word1 word2 word3 word4";
$word = explode (" ", $string); // or use the split function

for ($cnt=0; $cnt<sizeof($word); $cnt++)
{
if ($word[$cnt] == strtoupper($word[$cnt]))
{
$word[$cnt] = strtolower($word[$cnt]);
}
}
