PHP has a built in csv parser: <a href="http://php.net/manual/en/function.fgetcsv.php" rel="nofollow">http://php.net/manual/en/function.fgetcsv.php</a>

I'd recommend using the parser and then writing your data back out using fputcsv().

I am assuming each line is a string 

<pre><code>$mystring="web,search,web2.0,1,seo,networking,social";
$temp = explode(",", $mystring);
$mystring="";
for($i=0;$i&lt;count($temp);$i++) {
 if(is_int($temp[$i])==false)
$mystring+=$temp[$i];
if($i &lt;count($temp)-1)
$mystring+=",";
}
</code></pre>

<pre><code>web,search,web2.0,1,seo,networking,social
web,search,web2.0,3,seo,networking,social
web,search,web2.0,4,seo,networking,social
</code></pre>

How do I remove <code>1</code>, <code>3</code> and <code>4</code> from above lines??

how do I remove numbers from this comma seperated texts?
