Stuff like [^ makes it hard to understand .

$checkthis="555 :55;55_55";
$ok="0123456789 \.";
string_reject($ checkthis,$ok)

function string_reject($ mystring,$allow ed)
{
return ereg("[^".$allowed. "]",$mystring );
}

Perhaps sombody on here could alter/add the appropriate code to do what
you require it to do .

preg not ereg but it can easily do what you want.
I got this from the PHP manual comments (I think)

/**
* Validates and reformats (if necessary) a North American telephone
* number. Telephone number is reformatted to the following format:
* 123-123-1234 x12345
*
* @param string $phone
* @return string or FALSE
*/
function checkTelephone( $phone) {
$na_fmt ="/^(?:\+?1[\-\s]?)?($\d{3}$|\ d{3})[\-\s\.]?"; //area
code
$na_fmt.="(\d{3 })[\-\.]?(\d{4})"; // seven digits
$na_fmt.="(?:\s ?x|\s|\s?ext(?: \.|\s)?)?(\d*)? $/"; // any extension

if( ! preg_match($na_ fmt, $phone ,$match) ) {
return false;
} else {
$ret = '';
if( substr($match[1], 0, 1 ) == '(') {
$ret .= $match[1];
} else {
$ret .= $match[1].'-';
}
$ret .= $match[2].'-'.$match[3];
if ($match[4] != '') {
$ret.=' x'.$match[4];
}
return $ret;
}
}

thanks for your code: I've been able to do as simple as:
$number = ereg_replace("[^0-9/.]",".",$numb er);
(we decided to remove the "space" but may be easely be added I think).

a "space" or a "dot"??

Lets give some examples:

555/55.55.55
555 55 55 55
555.555 555

It looks to me that you want to replace all characters which are not a
number, a dot a space or a slash to "dot", is this true?? then you
might try:

$newstr = preg_replace("/[^\d.\/ ]+/", ".", $oldstr);

(untested)

I added a plus in the pattern /[^\d.\/ ]+/ to replace also something
like:

555:55;_@55_55 to 555.55.55.55 instead of 555.55...55.55

I havent got my head round regular expressions yet either - but it would
be easy to write a small loop to replace everything that wasnt
012345678/. with a space .

Can write it for you if you want .

Wrote it anyway as it could be useful to me some time in the future .

Quite luddite in method but seems to work fine .

<?php
$num="A_555. 01/2345jack678-90/.@Z";
print "Before processing = $num <br>";
include('number _check.php');
print "After processing = $fin <br>";
?>

The above on some webpage .

The following as a include file .

number_check.ph p

<?php

$ok="0123456789/.";

$clown=strlen($ ok); $clown=$clown-1;
$lisa=0;
while($lisa<$cl own+1)
{
$char=substr($o k,$lisa,1);
$millhouse[$lisa]=$char;
$lisa=$lisa+1;
}

$krusty=strlen( $num); $krusty=$krusty-1;
$lisa=0;
while($lisa<$kr usty+1)
{
$char=substr($n um,$lisa,1);
$jimbo[$lisa]=$char;
$lisa=$lisa+1;
}

$lisa=0; $fin="";
while($lisa<$kr usty+1)
{
$homer=0; $pass=0;
while ($homer<$clown+ 1)
{
if ($jimbo[$lisa]==$millhouse[$homer]) {$pass=1;}
$homer=$homer+1 ;
}
if ($pass==0) {$jimbo[$lisa]=" ";}
$fin=$fin . $jimbo[$lisa];
$lisa=$lisa+1;
}

?>
