I may have repeated some  yours - but looking at your code, am sure it would capture these too.. :)</div>

Hi everyone,<br>
<br>
I&#39;m trying to create some code to validate/sanitize mobile phone numbers entered by users, for use with SMS gateways.<br>
<br>
So far I have the following:<br>
<br>
729974802 becomes: 254729974802<br>
0729974802 becomes: 254729974802<br>
0 729 974 802 becomes: 254729974802<br>
254 729974802 becomes: 254729974802<br>
<a href="tel:%2B254%20729974802" value="+254729974802" target="_blank">+254 729974802</a> becomes: 254729974802<br>
(254) 7 29974802 becomes: 254729974802<br>
<a href="tel:%2B%28254%29%207%2029974802" value="+254729974802" target="_blank">+(254) 7 29974802</a> becomes: 254729974802<br>
<a href="tel:%28%2B254%29%20%280%29%207%2029974802" value="+254729974802" target="_blank">(+254) (0) 7 29974802</a> becomes: 254729974802<br>
<br>
However I am not sure that I have captured all the different ways that a Kenyan mobile-phone number could be entered.<br>
So the question to you all is: are there more ways a number could be entered ?<br>
<br>
n.b. if anyone is interested the code for the above is (in php):<br>
$phone = &#39;254&#39; . preg_replace(&#39;/^\+?(\(?\+?254\<u></u>)?)?(\(?0\)?)?7/&#39;, &#39;7&#39;, str_replace(&#39; &#39;, &#39;&#39;, $input));<br>
<br>
