Hello Everyone, As the title implies I need help extracting a name out of a string, my knolwedge of regular expressions is pretty limited. The strings I will be working with will look like this: 12345 Aragon Denvil L. 123-1234 A123456 AragonD AragonAD@fake.mail.us 1000001234 ABC-ABC 123ABCD123 ABCD 1234 A1234 ABC12345A1 AB123AB 17-Feb-12 54321 Mgmt Chan Jackie 123-4321 ABC4321 ChanJ ChanJ@fake.mail.us 0 ABC-ABC 123ABCD123 ABCD 1234 A1234 ABC12345A1 AB123AB 17-Feb-12 From the first line I would be trying to extract "Aragon Denvil L." and from the second "Mgmt Chan Jackie". Worst case scenario I could maybe get away with just extracting …

In brief, I am puzzled as to why `~^[0-9]*?\|[0-9]*?\|.*?\|.*?\..*?\|2\|[0-9]\|.*?$~m` matches `1362526368|5|Corinne E. Fischer|fischer.jpg|3|3|FischerC@smh.ca|416-864-5320|1|2|3|4|5` Note the |3| after fischer.jpg when the pattern clearly has a \|2\| in that location. Now I understand that it must be the numbers at the end that are messing with the match but I don't really know how to fix it (the numbers at the end don't have to be numbers but can be any characters). This shouldn't be an issue later when I fill in proper data but I just want to know where I'm going wrong for future reference and for my peace of …

I used "/<name of product>/" as my …

I have a problem in a payment solution I have made. In this, I use ereg to extract a returned Transaction ID from the payment provider, and with PHP 5.3 this does not work anymore. The code used was: ereg('<TransactionId>(.+)</TransactionId>',$resultat_3,$c); I have tried to use this instead: (but it doesn't work) preg_match("/<TransactionId>(.+)<\/TransactionId>/",$resultat_3,$c); Does anybody have an idea what to do?

Hi guys, I would like to validate some form input, and only allow the folowing: letters, numbers, /, - if(!preg_match("*[0-9A-Za-z,-,/]", $url_key)){ $erros[1] = '<small>Error submitting url key!</small>'; } Which is not working..

So, I have this wordpress driven site, and I have a plugin written that runs when a post is viewed. The content of the post is loaded into $content. I also have a database of keywords and links to other posts on my site. I want to search the $content for any matches to any of the keywords, and replace the text with the the link associated with the matching keyword. BUT I can't just use str_replace(); because sometimes matching keywords also match image file names. Big problem. I'm kind of stumped, does an existing function allow for a simplistic …

Friends, I'm rushing towards deadline and I think that makes me do childish mistakes. Here I have validation that requires regex and each time I input valid expression preg_match returns false. It is long now I'm trying to spot error but I cannot! I have googled and AFAICS, things seems alright please help me spot the error.

Hi, Can someone lead me in the right direction on how to write a preg_match. I have username and password in the DB. And the username should be case sensitive, accordingly to whatever is in the db. And it should only be able to contain numbers and letters. I have this, but I havent used preg_match before, sp I am a little confused on how the syntax works and where to put what i want. [CODE] if(preg_match('/^[A-Z'.-]{2-20}$/i',$_POST['username'])){ $username = trim($_POST['username']); $username = mysqli_real_escape_string($connection, $username); } [/CODE] Hope somene can explain me the way this chinese is to be translated :-)

Hello all, I am trying to use more regex but I can't seem to get this to work. The aim is to check inputs for either [url, [link or <a href: [CODE] $islink = false; foreach($_POST as $k => $v){ if((preg_match("/[url|[link|<a href/i", $v)) > 0 ){ $islink = true; } } #gather data in sanitised variables $name = make_safe($_POST['name']); $feedback = make_safe($_POST['feedback']); $refer = make_safe($_POST['refer']); if($name && $feedback && !$islink){//process} [/CODE] The if keeps executing, Any help would be great

Anyone have an idea what the regex would be for preg_split to split a string at a semicolon ([icode];[/icode]), but ignore any quoted (single or double) parts as well as ignore escaped ([icode]\;[/icode]) semicolons?

[code=php] //split string into characters and process... function split_at($input, $splitAt=";"){ $on=1; $j=0; $output[0]=""; for($i=0; $i<strlen($input); $i++) { //when a quote is reached then set $on switch off to ignore quoted part //untill another quote is reached then it …

Hello people, I'm trying to collect some data stored between <body> and </body> tags inside a string. Here's a piece of the code i'm using: [CODE] $regex = '/<body>(.*?)<\/body>/si'; preg_match($regex, $content, $content); $content = $content[0];[/CODE] This works perfect, except that it also includes the above mentioned tags. I would just like to grab the content in between those tags and store it. In other words, only store the (.*?) part of the regex. Anyone have an idea how to solve this? :)
