PHP - Regex To Grab Last Pattern Only
For example:
$text = preg_replace_callback( "/([@][a-zA-Z-0-9]+)/" , "umentions", $text, 1);That 1 parameter means the maximum times it will iterate right? So If I'm doing: @Nexus @Cupcake @George it will return: My problem is. I only want it to iterate over the last match in my function: function umentions($matches){
vdump($matches);
return "(here you would replace: ".$matches[0]." with something)";
}
How is it possible to use limit, and only iterate the last match not the first?
Edited by Monkuar, 22 January 2015 - 08:46 AM. Similar TutorialsIn the below example, we match 0 or more alphanumeric characters in the beginning and 0 or more alphanumeric characters in the end. Then we create 4 groups. Each group has "?=" which means "the next text must be like this". Now in first group we match any character 8 or more times. The next group we match 0 or more characters and a digit. In the next group we match 0 or more characters and a lowercase letter. In the next group we match 0 or more characters and an uppercase letter.
<?php
$password = "Fyfjk34sdfjfsjq7";
if (preg_match("/^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).*$/", $password)) {
echo "Your passwords is strong.";
} else {
echo "Your password is weak.";
}
?>
My question is do these four groups impact each other? That is, the fact that the first group has 8 or more characters means that all the groups must have 8 or more characters. The fact that the second group has a digit means that all the groups must have a digit. Or do they work exclusively meaning that a 4 character word with a single digit would match this pattern, even though first group says it must have 8 characters.
$pattern="/[+][0-9]+[^a-zA-Z*-+!|@#$%&*(){\/}]/"; //
$subject="+3706*0805595";
$ans=preg_match($pattern, $subject, $matches);
print_r($matches);echo "ans=".$ans;
gives output
Array ( [0] => +3706 ) ans=1Where is my mistake. How to formulate pattern which does not accept string which contains letters or special characters. String must start with +, contain digits. Hey guys. So I'm trying to write a script that replaces footnote citations in one format with footnote citations in another format. For example, the text will read: "Then he went down the street.[1] That is where the police found him [2]. They immediately arrested him at the house. [3]" And I would like the script to find the [ #] strings and replace them with {#} ... so that the string reads: "Then he went down the street.{1} That is where the police found him {2}. They immediately arrested him at the house. {3}" Note that there will be double, and even tripple, digit footnotes, so the script has to be able to recognize [##] or [###] and replace the brackets with {} accordingly. I'm not really sure how to do this, since the "pattern" is constantly changing depending on the number between the brackets. Ideas? Thanks! Ok, so basically I have every column in the link below to work right and have the data for each column displayed....except for "Person" column. http://trigamer.com/forums/newest.php?fid=1 If you check there, you can see the posts, but not the poster. I'm thinking the 7th line from the bottom is the issue? Below is the PHP code for that section: Code: [Select] <!-- list threads--> <?php if($threads) {?> <tbody> <?php while($thread = mysql_fetch_array($threads) ){ #get last user to post $last_user = fetch("SELECT user FROM posts WHERE tid = ".$thread["tid"]." ORDER BY dateline DESC LIMIT 1"); if(!$last_user) $last_user = array(); ?> <tr bgcolor="#202025"> <td class="threadIcon"><img src="/images/posticon.png" /></td> <td class="threadTitle"><a href="replythread.php?tid=<?php echo $thread["tid"];?>"><?php echo $thread["title"];?></a></td> <td class="threadReplies"><font color=white><?php echo $thread["replies"];?></font></td> <td><font color=white><?php echo $last_user[0];?></font></td> <td><font color=white><?php echo date("m-d-Y",$thread["dateline"]);?></font></td> </tr> <?php } ?> </tbody> <?php }?> <!-- //end list threads--> (example I looked at: http://develturk.com/tags/selfinstance/) I've looked into the singleton pattern and a few examples. I've understood most of its concept, but I still have a few things puzzling me. I noticed that you're not supposed to allow cloning (obviously) or the construction method as it shows in an example: //this object can not copy //except the getInstance() method. private function __clone() {} //prevent directly access //we want acces this only from getInstance method. private function __construct(){} Do I also have to do this for child classes, or just the parent class? I have a questions regarding Singleton Pattern in this video: http://www.youtube.com/watch?v=-uLbG7nJCJw&feature=plcp&context=C49f92beVDvjVQa1PpcFMxdGEHDoxYON2LEGpH0krK5UV1HfoVHGM= Using the singleton pattern, isn't possible to have methods that aren't static? In this video it shows nothing but static methods. Also, after creating the class object like so: $database = Database:Connect(); How would I go about using normal functions with that object? Say I had a query function. I can't do this: $database->query(); So what would I do? :/ - Thanks for any help regarding this. Hey Guys. I am learning about the Enterprise pattern, and to me it seems like its the same as the MVC pattern (which I learned about)
Do they work the same??
For those who know Martin Fowler's Patterns of Enterprise Application Structure, that is what I am referring to as the enterprise pattern
Edited by eldan88, 13 October 2014 - 10:24 AM. How to make "hints" as dynamic varaible: So I was stumbling around with Repositories and Interfaces and got a decent grasp on it. However, I started running into abstraction and started to implement a little bit of the Factory design.
How often is this typically used? It seems like I should be using Factory with 90% of my Repositories since there are different types of Items, Tutorials, Random Events, etc.
Items
- Food
- Weapon
- Toy
Tutorials
- Newbie
- Farming
Random Events
- Coin Giving
- Item Giving
- Item Draining
Things like this... so all of them have similar methods involved. So they each have a base method, for example.. an Item child class would always have the use() method and a factory would determine which kind of object to initiate from your controller just from the item model being passed through. So therefore you can call use() on the repository instance it returns.
Then I was moving onto my tutorials and random events and it just seemed very similar.
So in most cases, will factories be a huge plus? Just wanted some general opinions from the PHP developers =)
Thanks!
Folks, " http://www.example.com/whatever/whatever.htm " how to Grab the Domain name from URLs? like "http://www.example.com" Any suh PHP Cde?

I'm trying to setup Paypal Pro on a website - have everything working - but need to grab the 4th & 6th key values from the results given from the Paypal response and having difficulty with the task.
See the code that prints the response and the response sent from Paypal below - I need to grab the values for [TRXRESULT] and [TRXRESPMSG]
echo('<pre>');
print_r($PayFlow->getResponse());
echo('</pre>');
and here's the response I get from Paypal on script execution - this is an example of a failed transaction:
Paypal Response
Array
(
[RESULT] => 36
[RPREF] => RPC5B24581A2
[RESPMSG] => Transaction failed: Fail to obtain approval for the online transaction
[TRXRESULT] => 23
[TRXPNREF] => EUJPC36F2092
[TRXRESPMSG] => Invalid account number: Unsupported Credit Card type
)
Again, I want to grab the values from [TRXRESULT] and [TRXRESPMSG] and assign them to local variables so i can work with them within the local php script.
Example: $trxresult and $trxrespmsg
Here's part of the class (file name is Class.Payflow.php find on Github) that pertains to this snippet of code in question:
Class.Payflow.php
/**
* @uses Gets the response from Paypal.
* @access Public
* @param None.
* @return Array/String - Returns an array of Paypal's response or empty string if not return.
* @example $PayFlow->getResponse();
*/
public function getResponse() {
if($this->response) {
return $this->response;
}
else {
return '';
}
}
Thanks in advance for help w/this one!
I'm trying to build a calculator for a game...but I'm stuck on the extracting part. I don't really know how to go about it (so if you know of a tutorial/handbook please link), but how I would I extract this data: //data to extract $name = "Robin hood hat" $currentprice = "3.3m" $change = "+11.5k" //display echo $name echo $currentprice echo $change from: http://itemdb-rs.runescape.com/results.ws?query=robin hood hat I know about get_file_contents and doing it line by line...but that turns into a pain with many things to grab. Is there a way of grabbing it by table definition similarly to the way Google Docs does? Google Docs link format: =Index(ImportHtml("http://itemdb-rs.runescape.com/results.ws?query=Robin hood hat", "table", 2),2,4) This goes to the 2nd table, 2nd row, and 4th column for the "Change" data. Right now I have a link list a-z and 0-9. you click one of those links and your taken to page listing all items that start with that character. currently I'm using: Code: [Select] SELECT * FROM my_table where LEFT(`my_item`,1)='$show' ORDER BY my_title ASCall I do right now is just add a link like ?show=a and everything that starts with a is listed. Now here is my problem. I want to listen all items that start with a numeric value listed all on one page instead of being spread across 0-9. If another solution becomes available I'd be more then happy to hear you out. But does anyone know how I can change my query to only list items that start with numbers? Hello,
I want to grab some data from this site, using a script.
But I am stuck right at the beginning. If you go to the site, you can make a selection with the drop-down-boxes and get some output. For example if you select (left side: text on page in dutch / right side: translation in english):
Selecteer competitienaam: Najaarscompetitie 2014 Select league name: Autumn League 2014 Selecteer competitiegroep: Eredivisie dames Select league group: Eredivisie ladies Selecteer weergave: Programma (incl. uitslagen en stand) Select view: Program (including results and position) Optioneel poule filter: De Treffers R Optional group filter: De Treffers R Selecteer poule(s): Eredivisie - Poule A Select group(s): Premier League - Group A I want to grab the output you get after making all the selections. When I look at the webbrowser's page source the selections (drop-down-boxes) are inside an iframe from another domain: <iframe src="http://www.nttb-competitie.nl/" width="100%" height="1200" scrolling="yes" frameborder="0" name="NTTB_Competitie"></iframe>I figured out: First, the script gets url: http://www.nttb-competitie.nl/selectie.php?anr=0And after last selection it gets url: http://www.nttb-competitie.nl/web_programma.php?reset=0&pidString=1009267&sc=0&vastgesteldeAfdelingsnr=0&cnid=10085&cid=10704&view=programma&pf=1269&pid=1009267My problem is when I copy those URL's in a webbroser 's address bar, I get a page with only the words: Ongeldige aanroep!Which means "Invalid Call!" So my question is: How can I grab the data instead of this stupid message? Is it even possible or is it somehow protected? Please help! Hey guys! I haven't really coded teh exact query for this yet. But what I want to do is I want to grab multiple results that are the same and only display one BUT also grab DIFFERENT results from the SAME table the same way. Let me give an example here... Lets say this is my table: id - name - image 1 - apple - apple.gif 2 - grape - grape.gif 3 - orange - orange.gif 4 - apple - apple.gif 5 - apple - apple.gif 6 - orange - orange.gif I want it to diaply like this: Apple -apple.gif- Quantity: 3 Orange -orange.gif- Quantity: 2 Grape -grape.gif- Quantity: 1 My query for LIMIT 1 would look like this, but it only grabs one result toal.. i think.. I would also be grabbing stuff from two different tables, which wouldn't be an issue. in this case, i want to grab the QUANTITY form one table, )the uitems table) and the image and name from the items table) the uitems query is also grabbing theitemid to use with the items table.. Code: [Select] \\ this would be getting the quantity \\ $query = "SELECT * FROM uitems WHERE username='$showusername' AND location='2'"; $thisthat = mysql_query($query); while($row = mysql_fetch_array($thisthat)) { $quantity = $row['quantity']; $getid = $ow['theitemid']; } \\ now getting the item info \\ $itemquery = "SELECT * FROM items WHERE itemid='$getid'"; $item = mysql_query($itemquery); while($thisrow = mysql_fetch_array($item)) { $name = $thisrow['name']; $image = $thisrow['image']; $actualid = $thisrow['itemid']; } So basically, I want to be able to be able to grab one row of every kind that is there. How can I do that? Thanks so much in advance!! =D I am using this to get links from a page: preg_match_all("/href=(\"|')(.+?)(\"|')/", $opt, $matches); $links = $matches[2]; Once in a while I get a link that may look like this: site.com/"><span What can I do to make my regexp better so it doesn't get the html?
