PHP - Naive Dog And Cat Regex Question?
All right, so I've been sober for YEARS and now all of a sudden I'm tempted to have just ONE.....
Similar TutorialsGiven the below rules and following browser input: user/joe/x This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=307000.0 Hi guys, I would normally research this myself, but I am in a hurry just now. My question is - how would I take a string like: "Customer Name" or "Product Cost Price" and produce a result where all upper case letters are made lower case and all spaces replaced by under-scores. Like this: "Customer Name" would become "customer_name", and "Product Cost Price" would become "product_cost_price" Many thanks for any swift help, S Hi Guys. This should- hopefully- be a pretty simple question for someone with regex experience to answer. I've been reading all the regex guides and tried various things but none have worked and I'm starting to get a headache. I've decided to just pitch the question here. How do I test if a string contains ONLY a certain character- but could be one or more instances of that character. In this case it's a comma. So: ',' -> Would return TRUE ',,,' -> Would return TRUE ',,,,,,,' -> Would return TRUE ',,,hello,' -> Would return FALSE 'hi,,,' -> Would return FALSE Thanks in advance! I have been playing with reg ex patterns for the last couple of hours. I realized I have been coding in security a hole. But for the life of me I don't know the answer. In preg match it will return a 1 true. So the code below is saying if you find anything that is not one of these values the condition is true. Meaning anything but a-zA-Z true is this correct? How do I make it so if you find anything but a-zA-Z return false? Code: [Select] if ( preg_match('/[a-zA-Z]/', $_GET['contact'] )== 1) Ok, my first post here (earlier today) was a huge help, so here's a second... I have the following PHP code: $name = $row['NAME']; $nameTrimmed = $name; if ((strlen($nameTrimmed) > 20) && (strlen($nameTrimmed) > 1)) { $whitespaceposition2 = strrpos($nameTrimmed," ",5); $nameTrimmed = substr($nameTrimmed, 0, $whitespaceposition2); echo $nameTrimmed . "..."; } if ((strlen($name) <= 20) && (strlen($name) > 0)) { echo $name; } This is working as expected. However, many of the "name" fields in the DB contain &trade; and &reg; strings, which inflate the count of each product title. Since I'm using the strrpos to limit the length of the longer product names (due to limited space in the layout), I would like to show as many full titles as possible. Many are being cut prematurely short due to the extra characters from the symbols. Do I need to run all this through a regex filter before I count it? If so, can anyone share an example of code I could try? Regex has never been my weak point, let alone my strong point. Or is there something else I haven't thought of? Any help is greatly appreciated! I want to make it so if($message=="" . $cmdPrefx . "deleteall: "){ echo substr(strrchr($message, ' '), 1); Doesn't use =="something" How can I make it so anything after deleteall: is a wildcard? I'm assuming using regex, but have no idea how Hey Guys,

hello. There is a project i take and i can't handle it. the project goes like this. I get site code by file_get_contents function into variable. Than I need to find the iframe and delete it from the variable. for example the code i getting from the file_get_contents is looking like this : <html> <body> This is site ! <iframe> LINK </iframe> </body> </html> now , simply i can track the iframe and delete it just like this. $str = preg_replace('/\<{1}iframe[a-zA-Z0-9=+\/\'.]/' , '' , $str);/** this is not the right regex i use , the full one contain all chars except < .**/ So I can find the < symbol and than delete all iframe section. the problem come when I get code like this. <html> <body> This is site ! <iframe> <iframe>LINK </iframe></iframe> </body> </html> So , from here I can't handle it since I don't know where the iframe ends since there is many < symbols. Second question is maybe with regex i can handle something like this? looking for start , than get everything between and stop at the end. $reg ='/^\<{1}iframe .+\<{1}iframe\>{1}/i'; Is that possible to do something like this with regex? any suggestions how to make it done? hope i was clear. thanks , Mor. This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=344155.0 Quote from: Mike Solstice on April 14, 2011, 12:24:45 AM Ok, that works if I run it CLI or though phpMyAdmin, but won't if I try it in php Code: [Select] $remcomma = "UPDATE top_train SET deaths = replace( replace(field_name, ',', ''), '"', '' )"; mysql_query($remcomma); I assume because of the quotes used in the regex. I tried escaping the " Code: [Select] $remcomma = "UPDATE top_train SET deaths = replace( replace(field_name, ',', ''), '\"', '' )"; mysql_query($remcomma); Which broke it altogether. Anyone have any ideas? Thanks! Moved here since that thread was marked as solved & it's more of a PHP issue at this point anyway. Any & all help is greatly appreciated! For a very 'loose' email address validator, does the following regex need the backslash before the dot?
^\S+@\S+\.\S+$
(Checks for anything@anything.anything but I'm gonna change that to anything.anything to make it even 'looser')
I tested with and without the backslash using rubular.com and it seems superfluous but I'd like a second opinion or two please.
ALSO: does rubular.com use the right engine to be correct for php? I hope so coz it's the first time I've been able to fully understand some regexes I've been blindly implementing for some time!
Many thanks in advance
I am building a whitelist based bbcode sanitiser that allows only permitted bbcode element (the
tag. All other bbcode elements will be rejected regardless of what they are. Also, this system should reject empty bbcode tag This is the function below: $val = 'This is a post with code, [code]cmmcxm[/code]'; /* The negative lookahead regex contruct in the function below ensures all opening square brackets must be followed by this regex inside the lookahead(code\](.)+\[\/code\]) */ function isSuspect($val) { // create a pattern to whitelist allowed bbcode phrase $pattern = '/[(?!(code\](.)+\[\/code\]))/i'; // if one of the suspect phrases is found, reject \[(?!(code\]\[/code\])) if (preg_match($pattern, $val)) { return '<div id="login-alert" class="alert alert-danger col-sm-12">You can not post that, it appears you may have included banned words or code tags in your post.<br/>If you think this is not the case, kindly contact the portal administrator <a href="#"><img class="warning" src="assets/img/icons/mail-black.png" alt="" /> here</a></div>'; } } echo isSuspect($val);This function is not validating $val = 'This is a post with code, cmmcxm'; and I was thinking it should. I would appreciate inputs to finish this. Thanks. hey guys im trying to make a regual expresion for a password with the conditions that it must contain 2 of each character: upper case letter, lower case letter, number or symbol...i have the regular exprssion below individually but how do i put it into one expression please?
possible matches:
des$tramic
destram1c
Destramic
^ (?=.*[A-Z].*[!@#$&*]) // upper case letter with symbol (?=.*[A-Z].*[a-z]) // upper case letter with lower case letter (?=.*[A-Z].*[0-9]) // upper case letter with number (?=.*[!@#$&*].*[0-9]) // symbol with number (?=.*[a-z].*[!@#$&*]) lower case character with symbol (?=.*[a-z].*[0-9]) // lower case character with number $thank you Hi. I am trying to extract the main url from a string.
For example.
I want to extract:
"http://google.com" from "http://google.com/search/pic.jpg"
"https://secure.co.uk" from "https://secure.co.uk/secure/secure.gif"
I am able to do this with this code, where $url is the url:
preg_match("http://(.*?)/", $url, $matches);
preg_match("https://(.*?)/", $url, $matches);
Is there away to consolidate this into one regex search? Or am I being picky?
Thanks!
