PHP - Generating A Password Without The Letters 'oh' Or 'el' Or The Numbers 1 Or 0
Maybe it's a Regex question, but I'm wondering how one would go about generating alphanumeric passwords that do not contain either the letters 'oh' or 'el', or the numbers 1 (one) or 0 (zero)?
In other words, the p/w can contain any letters of the alphabet - apart from 'oh' and 'el' - and any digits from 2 to 9 inclusive. The p/w length is not critical - let's say 8 characters. Thanks in advance for your help. Similar TutorialsThis topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=333172.0 Hi Guys
I have a regex conundrum that at first I thought would be very easy but then appears to be quite hard :/
I want to match a string with a regex where the regex can only pass if it contains letters and numbers (nothing else) and it has to contain at least one of each.
I've been trying out lookaheads but just can't get it right.
Any help is appreciated.

I'm certain this has been done a hundred times before, but I have been unable to find any information on an efficient way of doing this: I'm creating a membership system, and the password for new users needs to contains both numbers and letters. How do I go about checking this? The key is not that it contains only numbers and letters, but that it contains both. The password cannot be all letters or all numbers. Know what I mean? Cheers guys and gals. I need users to input ONLY numbers or letters with numbers. How can i go about fixing that. Thank you. Can I somehow mix letters with numbers to create an array with range()? e.g. I want my array for postcode ranges such as array('AB1','AB2', 'AB3', 'AB4', 'AB5', 'Ab6', 'AB7', 'AB8', 'IV5', 'IV6', 'IV7', 'IV8', 'IV9', 'IV10'); I know I can do range(1,8); but was wondering if there was something along the lines of range("AB1", "AB8"); Hey. I been using a function to check if a string contains only letters which is: ctype_alpha But i would like to change it to allow numbers 0 to 9 and the letters is there a function to do that in PHP i can't find it.

For example: $exstract['center_tabOpBody_0'] =5 $exstract['center_tabOpBody_1'] =6 $exstract['center_tabOpBody_2'] =8 $exstract['center_tabOpBody_3'] =1 Should yield: ARRAY( = center_tabOpBody_1,center_tabOpBody_2,center_tabOpBody_3 // <-----15 [1] = center_tabOpBody_0 //<----5 ) Is there some simple function do do the "efficiency" sort? Thanks, Vadim Hello PhP Freaks forum In the past weeks ive been trying to make a website, where you can register. Everything seems to work except my cherished Change password feature. Everytime you try to change the password, it just resets it to nothing. Here is the code below. <?php if(isset($_SESSION['username'])) { $username = $_SESSION['username']; $lastname = $_SESSION['lastname']; $firstname = $_SESSION['firstname']; $email = $_SESSION['email']; echo " <h4>Options for:</h4> $username <br /> <br /> First name: $firstname <br />Last name: $lastname <br /><br /><h3>Want to change your password:</h3><br /> <form action='?do=option' method='post'> Old password <input type='password' placeholder='Has to be between 5-15 digits' name='password' size='30' value='' /><br /> <br /> New Password<input type='password' placeholder='Has to be between 5-15 digits' name='newpass' size='30' value='' /><br /> <br /> Confirm new password <input type='password' placeholder='Has to be between 5-15 digits' name='passconf' size='30' value='' /><br /> <center></div><input type='submit' value='Submit'/></center></form>"; }else{ echo 'Please login to view your options!'; } $password = $_REQUEST['password']; $pass_conf = $_REQUEST['newpass']; $email = $_REQUEST['passconf']; $connect = mysql_connect("Host", "User", "Password"); if(!$connect){ die(mysql_error()); } //Selecting database $select_db = mysql_select_db("My Database", $connect); if(!$select_db){ die(mysql_error()); } //Find if entered data is correct $result = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password'"); $row = mysql_fetch_array($result); $id = $row['id']; mysql_query("UPDATE users SET password='$newpass' WHERE username='$user'") ?> And i do know that i dont have a if(Empty($newpass)){ Die(Please fill out the new password) } Or any security on the others, but the problem just seems that it resets the password into nothing Hope i can get this fixed Best Regards William Pfaffe <?php

How in php using the preg_replace php function can i allow only the basic english a-z letters, numbers 0-9 and unicode code letters and remove anything else? I'm looking for a function that will check a string for letters and spaces...boolean preferibly Hello, I have a script coded in PHP and alot of JavaScript and I have problems with languages like Arabic and Hebrew ( non Latin characters) .. It is showed as question marks in the website like this ( ?????????) and in the database .. I converted the SQL Database from Latin Swedish to UTF-8 in phpmyadmin and now the database is correct but the website is still in question marks . In every HTML code you can see this : ........... content="text/html; charset=utf-8"/> and I tried changing the same php pages to UTF-8 using text editors but nothing happened . any help will be great. thanks. Does anyone knows if FPDF supports Norwegian letters or not? When I write codes of letters it is not showing letter. Are there any command to specify charset? For example in this code is it possible to specify charset? $pdf=new FPDF(); $pdf->AddPage(); $pdf->SetFont('Arial','',14); $pdf->Write(5,'Følgende '); Would someone tell me how to allow foreign letters, normal english letters and numbers using the preg_replace php function? I'm looking for a method to replace everything between brackets. The patterns that I'm looking for are defined: "/\[([2-9TJQKA][hdcs])\]/" The pattern inside the bracket could accur 2 or even 3 times inside the brackets. For example first occurance would be [Ac Kd], here I want to replace Ac into an imge and Kd too. Later in the text I will most of the time get 3 sets, instead of two: [Jc Td 9d]. The sets always consist of [2-9JQKA][hdcs] and also in this order. Another example: [2d 2s 2h], or [3s 4h 5c]. If I use the following function, it would not work optimally because some texts do contain some of those sets which should not be converted, ONLY the sets between the brackets:
$haystack = setReplace($haystack);
function setReplace($haystack)
{
$array = array("2s", "2h", "2d", "2c",
"3s", "3h", "3d", "3c",
"4s", "4h", "4d", "4c",
"5s", "5h", "5d", "5c",
"6s", "6h", "6d", "6c",
"7s", "7h", "7d", "7c",
"8s", "8h", "8d", "8c",
"9s", "9h", "9d", "9c",
"Ts", "Th", "Td", "Tc",
"Js", "Jh", "Jd", "Jc",
"Qs", "Qh", "Qd", "Qc",
"Ks", "Kh", "Kd", "Kc",
"As", "Ah", "Ad", "Ac");
for($i=0;$i < count($array);$i++)
{
$result = str_replace($array[$i], "<img src=\"/images/".$code[$i].".png\">",$haystack);
}
return $result;
}
Any ideas?
