PHP - Random Character Genorator
I would like to have a generator that basically creates a certain number of mixed characters.
For example 6 characters which use A and B It would randomly produce things such as ABAABA BABABB I cannot think of any basic ways of achieving this. Any help would be appreciated even if its written rather than code. Thank you in advance. Similar Tutorialsi have to tables... forums & subscription i would like to insert a random character string into 'forums' to be used as a subscription id. and then have the same random string to be inserted into 'subscription' Hey all, I'm looking to produce a random 10 character string like: abcABC0123 when the below method is called: <?php function randomize(){ $chars = explode(' ',(range("a","z"))) . explode(' ',(range("A","Z"))) . explode(' ',(range("0","9"))); $pass = ""; for($i = 0; $i < $len; $i += 1){ array_push($pass,$chars[rand(count($chars)-1)]); } return $pass; } var_dump(randomize(10)); ?> But the randomize method is not returning desired result. Any idea what I'm doing wrong? Thanks for response. sorry, this is kinda annoying to look at but its the best way to show my problem... this : Code: [Select] $headers = "From: $email_from\r\n"; $headers .= "Content-type: text/html\r\n"; $email_message ='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' .'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'; mail("njdubois@gmail.com", $checktype . " Comp Check Submitted from ncaappraisals.com", $email_message, $headers); gets me: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx! xxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Do you see the '! ' ?? why why why why why why?!?!?! I'm going freaking crazy trying to figure this out!!!! Thanks a billion in advanced! Nick As above, I have a lottery style site that picks a random number between 1-8 but my users complain for some reason that this is not enough. So i was told to look into using fopen and random.org to generate a random number. Anyone have experience of this and perhaps a code snippet for me to look at and possibly use? help will be appreciated. I know via firebug that the correct parameters were passed to my process page and the parameter being passed that in caused issues on the process page is $characterIDList. What's causing the issue is that its not inserting the value into the insert query. The rest of the insert query works fine. process page $characterIDs = explode(',', $_POST['characterIDList']); foreach($characterIDs as $itm){ $id = (int)$itm; } $defaultcharid = (int)$characterIDs[0]; $query = "INSERT INTO `handlers` (username, password, firstname, lastname, email, status_id, isadmin, default_character_id, creator_id, datecreated) VALUES ('$username','$password','$firstname','$lastname','$email','$status','$admin', '$defaultcharid', 1, NOW())"; HI all, something that keeps bothering me is that i do not fully understand the usefullness of the \n newline character. When i use for testing in a string it doesn't show the effect in my browser. Only when I press view source I can see that right after the \n character the code jumps down 1 line. Does anyone know how and when to use it? I have see it with the php mail function, but i don't really understand why they use it. If someone could enlighten me i would be very happy I got another problem. It is a counting characters. When I reload text from database, I want to count how many characters are in text. The problem is that I use the timymce, and there is a tags </p> and formats <span> and other formats. How can I count characters without those format, just pure characters entire text? I need a php code. And some plus - text is in utf8 coding in database with utf8 bin. I have problem, there are users with "?" character in username, and their address to profile is /profile/username/. I have var: $username that is that username, now, how can i replace all that characters which cant open users profile.. I mean for "?" i need to put "%3F", how can i replace? I know with str_replace, but is there any other solution like htmlencode or something like that? :S Hi, does anybody know why I get a question mark inside a diamond shape where a pound sign should be when i retrieve data from a mysql database? I have tried using latin1_general_ci and utf8_general_ci and they both do the same, don't know whether that is anything to do with it or not? Any help would be greatly appreciated. All, I have a zip code and for example the zip code is 01101. How can I determine if the first character in this is a zero? Thanks in advance. Hey, I'm having an issue with using Wikipedia's OpenSearch API - it sometimes gives me characters in a unicode format: "\u00f1" and I would like to convert back into a correctly displayed format (in this case, n-tilde; spanish n). Any suggestions? all i want is for when their is a _ to be replaced with a space so i tried these and neither worked Code: [Select] <?php $pmod = str_replace("_"," ",$p); $pmod = preg_replace("_"," ",$p); ?> so i was wondering if because this was in a while statement, is this the reason its not working, and if so how should i fix it (this is the while) Code: [Select] <?php while ($z <= $w){ $p = $multi[$z]; $pmod = str_replace("_"," ",$p); echo "<a href='tag.php?tag=$p'" . $p . ">" . $pmod . "</a> "; $z++; } ?> Thanks to the advice of others on PHPFreaks, I have decided that allowing any character for certain fields on my "Add an Article" form. However, I still want to define a length between 2 and 100. How do I re-write my RegEx to accomplish this? Befo Code: [Select] // Check HTML Title. if (empty($trimmed['htmlTitle'])){ $errors['htmlTitle'] = 'Please enter an HTML Title.'; }else{ if (preg_match('#^[A-Z \'.-]{2,100}$#i', $trimmed['htmlTitle'])){ $htmlTitle = $trimmed['htmlTitle']; }else{ $errors['htmlTitle'] = 'HTML Title must be 2-100 characters (A-Z \' . -)'; } } Here is my best guess... After: Code: [Select] // Check HTML Title. if (empty($trimmed['htmlTitle'])){ $errors['htmlTitle'] = 'Please enter an HTML Title.'; }else{ if (preg_match('#^[.*]{2,100}$#i', $trimmed['htmlTitle'])){ $htmlTitle = $trimmed['htmlTitle']; }else{ $errors['htmlTitle'] = 'HTML Title must be 2-100 characters (A-Z \' . -)'; } } Debbie so if I have a a string of text or something like Code: [Select] http://www.yahoo.com/ajhsijd908340 I can use str_replace to remove "http://" but what can I use to remove the "ajhsijd908340" if every time it is a different set of characters? Can someone help me with this. I think I need to use substr: how do I only echo out everything after the period ( ".") for example if I have "table.birthday" I want to echo: "birthday" I have a $string with this structure "word-word2 something-SECONDPART". I want to divide it to $string1 and $string2 by separating with the last "-". The point is that "-" exists in the first part, and I just want to make the second string after the last "-" i'm trying to an if statement so that a piece of code is only executed if a returned variable equals a letter in the alphabet(any letter) the variable is from a $_GET, and all i want to check is if the variable contains a letter. This is what i have so far, but it doesnt work $sort=$_GET[orderby]; if ($sort=="[A-Z]") { $read=mysql_query("SELECT * FROM films WHERE title LIKE '".$sort."%'") or die(mysql_error()); $result=mysql_num_rows($read); } else { $read=mysql_query("SELECT * FROM films ORDER BY title") or die("query failed"); $result=mysql_num_rows($read); } Any help would be great. |
