ereg_replace

Hello there,

I need help: I've a string that is used to write down a phone number that
comes from a form and would like to keep it as clean as possible. For
avoiding people to create twice an account using a different syntax.

For this the only char I'd like to allow are number 0-9, '/','.' and spaces.

I'd like to replace everything other by a "space".

Lets give some examples:

some allowed:
555/55.55.55
555 55 55 55
555.555 555

some not allowed and their changes:
555-55-55-55 -> 555.55.55.55
555,55,55,55 -> 555.55.55.55
555:55;55_55 -> 555.55.55.55
55555\55>55 -> 55555.55.55
and so on.

How can I do that ? I'm not confortable with ereg_replace, so if you could
give the final statement it would be greately appreciated.

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

function string_reject($mystring,$allowed)
{
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:
$number = ereg_replace("[^0-9/.]",".",$number);
(we decided to remove the "space" but may be easely be added I think).

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.php



<?php

$ok="0123456789/.";

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

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

$lisa=0; $fin="";
while($lisa<$krusty+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;
}

?>
