deprecated: Function eregi() is deprecated in

Hello

I have a Guestbook but after i have move my webhotel to a new
server i get this error, After what i can read is it because that the "eregi" dont work in the new PHP version and it shall change to "preg"

But i have no idea how to change it so good i am not to PHP

Deprecated: Function eregi() is deprecated in /mnt/webf/e2/35/53159135/htdocs/images/guestbook/include/funct_utiles.php on line 512

Line 512 : if (eregi("^[a-z0-9]$", $chr))

The whole code is this

function generatePwdGuest3($chrs=10){
$pwd = "";
mt_srand ((double) microtime() * 1000000);
while (strlen($pwd)<$chrs){
$chr = chr(mt_rand (0,255));
if (eregi("^[a-z0-9]$", $chr))
$pwd = $pwd.$chr;
};
return $pwd;
}

//----------

this is what i use for passwords:


function generatePW() {
$validpw='12345qwertyuiopasdfghjklzxcvbnm1234567890QWERTYUIOPASDFGHJKLZXCVBNM67890';
$strPW='';
for ($i=0;$i<8;++$i) {
$strPW.=$validpw[mt_rand(0,strlen($validpw))];
}
return $strPW;
}


so replace all the $strPW in this one to $pwd and replace function generatePW with generatePwdGuest3

this is based on me assuming this is to make a random password for the user

Hello

Then i get a new error in another file ...

eprecated: Function eregi_replace() is deprecated in /mnt/webf/e2/35/53159135/htdocs/images/guestbook/index.php on line 166 Deprecated

$chaine_smileys .= "<img src=\"".$chem_absolu."images/smileys/".$alex_livre_smileys_smiley[$i]."\" alt=\"\" title=\"".ucfirst(str_replace("_", " ", eregi_replace("[.]{1}(.)*$", "", $alex_livre_smileys_smiley[$i]))).

did that last one work? also, is this to do with smiles? aka bbcoding?

The las one worked fine with the text but give me a error in the index.php

but that i fix

was just to change generatePwdGuest3 to generatePW

Then now i get the new error as you can see in my topic or look at
my link

http://www.mitsucats.de/images/guestbook/guestbook.php

change all of the:


eregi_replace()


to


preg_replace()

That dident work

$chaine_smileys .= "<img src=\"".$chem_absolu."images/smileys/".$alex_livre_smileys_smiley[$i]."\" alt=\"\" title=\"".ucfirst(str_replace("_", " ", preg_replace(("[.]{1}(.)*$", "", $alex_livre_smileys_smiley[$i]))).

Parse error: syntax error, unexpected ',' in /mnt/webf/e2/35/53159135/htdocs/images/guestbook/index.php on line 166

That dident work

if i try with only one ( and not ((

$chaine_smileys .= "<img src=\"".$chem_absolu."images/smileys/".$alex_livre_smileys_smiley[$i]."\" alt=\"\" title=\"".ucfirst(str_replace("_", " ", preg_replace("[.]{1}(.)*$", "", $alex_livre_smileys_smiley[$i]))).

Just a personal though on password generators, you should remove 1(one) & l(lowercase L) & 0(zero) & O(capital o) & probably o(lowercase O) from the string as these are very similar characters and can cause confusion with the user if they are typing passwords in manually.

These days there are a lot of mobile users typing in passwords manually...

Just my thoughts..

I have download the complete script for the guestbok and i like it much and i have also
wrote to the owner of the script if he could help but nothing yet...

I am not so good to php. i am best to use dreamweaver.

Therefore i hope i can get help to fix this problem.

I thank you all for trying to help me ;)

change all of the:


eregi_replace()


to


preg_replace()

PREG and EREG do not use the same syntax. There are some simple patterns that work with both, but you can't simply change the name of the function and expect it to always work properly.

Limiting the characters in your random password generator isn't necessary since anyone on a desktop/laptop/smartphone is going to be able to copy/paste it and likely change it to something they can remember anyway.

Try something like this:
$chaine_smileys .= '<img src="' . $chem_absolu . 'images/smileys/' . $alex_livre_smileys_smiley[$i] . '" ' .
'alt="" ' .
'title="' . ucfirst(str_replace('_', ' ', preg_replace('/\..*$/s', '', $alex_livre_smileys_smiley[$i]))) . '" ' .
'/>';
I separated the img tag's attributes on to different lines to make it clearer.

Edit: here is what that regular expression does(removes the file extension):

\..*$

Match the character “.” literally «\.»
Match any single character «.*»
`- Between zero and unlimited times, as many times as possible, giving back as needed (greedy) «*»
Assert position at the end of the string (or before the line break at the end of the string, if any) «$»
