PHP - Match Dollar Symbol($) Using Preg_match
Hi
i want to match $ symbol from the string. I am using the following script Code: [Select] $str="ckj"; if(preg_match("/^$/",$str)) { echo "Dollar is found"; } else { echo "Not Found"; } Its not working fine. Can anyone help me out please. Similar TutorialsThis is my preg_match code:
preg_match("/(\d+)|(T)|(A)/", $link, $matches, PREG_OFFSET_CAPTURE, ($off-30)
It works and matches the number I want, except it only returns the first character in the $matches array. For instance, if the number it finds is 10, it only returns 1. Now I understand that is what preg_match does, but how would I make that regex ungreedy? I tried adding a *, but it just made an error, and preg match all would keep searching for strings after the first one. All I want is for the first number, regardless of the length of it, to be returned in full. Thanks for any help.
I am using preg_match() to perform a url regular expression match for a video embed function.
I have provided the third parameter of preg_match ($matches) therefore $matches[0] should contain the text that matched the full pattern, however I have noticed in the code example below, that the space after the query component of the specified url together with the first word after the space is captured and stored in $matches[0] as well.
$UserInput = "This is my video embed, http://www.youtube.com/watch?v=GXHijTS9_2g check it out .";
preg_match('@http:\/\/(?:www.)?(\w*).com\/watch\?v=(\w*\W?\w*)@', $UserInput, $matches);
var_dump($matches) provides the output below:
array (size=4) 0 => string 'http://www.youtube.com/watch?v=GXHijTS9_2g check' (length=48) 1 => string '' (length=0) 2 => string 'youtube' (length=7) 3 => string 'GXHijTS9_2g check' (length=17)What am I missing in the regex?

Hi All, I am trying to create a PHP code that will run a form, however i keep getting the error message Warning: preg_match() [function.preg-match]: No ending delimiter '^' found in D:\xampp\htdocs\HFCC\Scripts\mailprocess.php on line 55 Invalid email address entered. Go Back and try again attached is the complete copy of the code i am using, i have an email text box and label with the id 'email' also my method is POST and my action is Scripts/mailprocess.php. Please let me know if you need any additional details. Any help will be much appreciated. Thanks Please help me with this code. It keep appear in my website. "Warning: preg_match() [function.preg-match]: No ending delimiter '.' found in /home/kengsite/public_html/wp-content/plugins/statpress/statpress.php on line 1184" And this is how the line look like. if (!preg_match(".ico$", $urlRequested)) { return ''; } i have a form that has a price field, but if anything other than a decimal (0.00) a zero is entered into the database. There is the problem of people trying to add a dollar sign before their amount. What is the best way to validate a price amount to be entered into the database. The column in the database type is decimal(6,2). Any suggestions? What is the & symbol used for I have seen it in function setname(&$name){ $this->name =& $name; } Thanks I have looked on google and can't find it as i don't know what it is called. thanks Hello, Im getting a name from the url, for instance, index.php?name=C.-and-G The "and" is then converted to a & symbol and dashes converted to spaces. This then uses the new name "C. & G" to select a record from mysql. However, it does not recognise the & symbol, the name in mysql is "C. & G" but returns 0 records. Any ideas? Thanks! Easy One - What is the symbol for or? Example: && = and, right? What is 'or'? I am running php 5.3.2 on my local dev and on the server I am running php 5.2.5. In my log files I keep getting deprecated messages like: PHP Deprecated: Assigning the return value of new by reference is deprecated in /Users/xxx/dev/git/xxx/cake/dispatcher.php on line 677 Can I just delete & to get rid of this message or will that hose the script locally and on the server? I believe that php 5+ passes all objects as reference.

Hi, I'm looking through some code I have for setting up a rating system. It was a free open source code, which I need to change to work for my own site. I have it working, but I am now just looking through the code to try and understand it, and for the most part, I do. There is one part I am not familiar with, if somebody could help me please? Values involved; $current_rating = total rate value of votes $count = total number of votes cast Problem I have is the @ symbol here $rating=@number_format($current_rating/$count, 1); Does it format it to decimal places or something like that? It's probably something simple I know, but I am a relative newb. Thanks. Code: [Select] $mystring = "|Signature"; $findme = '|'; $pos = strpos($mystring, $findme); echo $pos; echo's 0 supposed to echo out 1....? why not work thanks How can I enable it to check for Code: [Select] | using strpos? What does it mean Like.. !@file_get_contents('url'); or.. !file_get_contents or @file_get_contents Trying to echo a string that contains a hash symbol. Instead of getting a hash symbol, I get %29. The code I am using is pretty basic -->$idx="#" . $idxA;<--, but as stated, when I echo $idx, it comes out as %29. (All of this is part of a form, get, attempting to pass a bookmark to the receiving program. Thoughts? So I have a simple query that adds a text record into a MySQL database table. It works great with exception of one thing. I noticed that if I have "&" symbol in my paragraph, the text after that symbol won't be inserted into the table. The text before that symbol will insert fine. It seems to be doing that only with & symbol; other symbols insert and show up fine. can anyone tell me why this is happening? hello i can't figure out how to modify a value from assoc array so with each recursion to add additional string to his: for example i have attribute=""; then call recursive function and i try to modify its value by concatenating "0"; or "1"; on the next loop to add again "0" or "1"; |
