Remove words with numbers from a long string

Hi, I have a string and inside this string I collect some phrases like:
$string = "holiday$ in portugal, algarve villa, alga1111rve holidays, algarve villa, villas in portugal,";
I want to remove the words like holiday$ and alga1111rve, and after I remove that words I get the string again preserving the commas(,), like:
$string = "in portugal, algarve villa, holidays, algarve villa, villas in portugal,";

Inside snipped code, you can see my script, but in final $coleta_keywords_final is empty!!!!!
Attention: $coleta_keywords_final, the string have allways data formated like "in portugal, algarve villa, holidays, algarve villa, villas in portugal,".

What I do wrong?

Regards, JC

$keep = explode(',', $coleta_keywords_final); 
$coleta_keywords_final = implode(" , ", $keep);
$words = explode(',',$coleta_keywords_final);
$result = array();
foreach($words as $word)
if(!eregi('[^a-z]',$word) or 
!eregi('[^0-9]',$word)) 
$result[]=$word;
$coleta_keywords_final = implode(',',$result);
echo "<br> $coleta_keywords_final <br>";

Somethimes the string can be too:

For help:
The variable $coleta_keywords_final contains "holiday$ in portugal, villa, alga1111rve holidays, algarve villa, villas in portugal, sun, black"

You can look at each word selectively. I will post an example that does this.
