PHP - Extractign A Substring...
Folks,
I want to extract something from a URL, i think we need to use regex for this. Example URL: Code: [Select] http://www.amazon.co.uk/gp/aw/d/B004JN01LW/ref=mp_s_a_1?qid=1305169492&sr=8-1 What we need to Extract: So we need to extract B004JN01LW from the URL. I tried to use substr() but i think its not useful for this purpose, can someone help me with Regex to extract this? Cheers Natasha Similar TutorialsSo I have a database with a bunch of dates in it. In this format 05/15/2011. And this is how I get that out. $data = mysql_query("SELECT * FROM location ORDER BY id ASC") or die(mysql_error()); while($info = mysql_fetch_array( $data )) { $date = $info['date']; }; echo "$date"; The resulted echo would be 05/26/2011 How do I get $date to echo out JUST 05? I'm trying to isolate the month. I think the method is using substrings, but I havent had any luck. Thanks any help would be great! Hi, how do I extract a substring? I just want to store "car" in a variable for other uses: Here is the original string: car/red/blue/gun/hit Any help much appreciated! I am using tinyMCE editor and uploading image from it.After form is submitted,it makes textarea's values as <img width="\"65\"" height="\"66\"" alt="\\"" src="\"images/logo.gif\""> cuz of wrong html,it is not displaying image.I tried to replace $_POST['elm2'] = str_replace('"\"','\"',$_POST['elm2']); $_POST['elm2'] = str_replace('\""','\"',$_POST['elm2']); but it is not replacing.How can i correct the HTML so that i display image. Hello, Does anyone know how to get a substrig by referencing other substrings around it? Ie, my string is the following: These are my favorite foods: <ul> <li id="1"> Pizza </li> <li id="2"> Burgers </li> <li id="three"> Hot Dogs </li> </ul> I need to get the ID of each list item, i know they will always follow "<li id=". I also need to get the text of each list item, i know they will always be before "</li>" Thanks! Let's say I have the string "Bob is my friend. Bob likes to eat apples. Goodbye!". I give a function that string, and the two strings "Bob" and "apples". It returns "Bob likes to eat apples". I seem to have trouble making this function. If I wanted it to return "Bob is my friend. Bob likes to eat apples" that would be much simpler, but I am trying to get the smallest amount of characters between the two strings. I tried doing this, but seem to either get stuck on an infinite loop or return the entire inputted string. Code: [Select] function between($strIn, $str1, $str2){ $pos2 = stripos($strIn, $str2); $pos = 1; $strStore = ""; while($pos>0 && $pos<$pos2){ $pos = stripos($strIn, $str1); $strStore = substr($strin, $pos, $pos2-$pos); $strIn = substr_replace($srtIn, $strtemp, ""); } return $strStore; } What it does it finds the first occurrence of "apples" ($str1) and then keeps finding and deleting every occurrence of "Bob" ($str2) until the position of "Bob" surpasses the position of "apples". As you can tell, it doesn't work. Could anyone help me out, or tell me what I am doing wrong? Hey all, I have method like this: Code: [Select] echo tinymce_tag($post->body); Basically the body property contains a string from database containing one or many paragraphs delimited by p tags: Code: [Select] <p>Hello World.</p> <p>Goodbye World.</p> I want to give all the paragraphs a class. This function will give the first p tag a class: Code: [Select] if ( ! function_exists('tinymce_tag')){ function tinymce_tag($content = ''){ $pos = strpos($content, '<p>'); if($pos !== false){ $content = substr_replace($content,' class="paragraph_styler"', 2, 0); } return $content; } } But I am not sure how to give all the p tags in the content variable a class. Thanks for response.

What I'd like to do is replace each instance of a single value with an array of values which get iterated through for each instance found. Think prepared statements that you don't have to call setString or setInt on. Here's a made up example. Code: [Select] $db->query = 'SELECT * FROM users WHERE user_name = ? AND user_role = ?; $db->params = array('hopelessX','admin'); $db->executeQuery(); //this contains a call to a private function that does the replace I have everything else working except this. It works if I specify an array of values to replace and do something like below, but I was hoping to not have to support that method of replace if I didn't need to. Code: [Select] $db->query = 'SELECT * FROM users WHERE user_name = :name AND user_role = :role; $db->replace = array(':name',':role'); $db->params = array('hopelessX','admin'); $db->executeQuery(); //this contains a call to a private function that does the replace I can do it that way if I need to or I could make some overly complicated thing that finds each instance of the question mark, replaces it with a unique value and then adds that unique value to a replace array similarly to the method in code block two but that defeats to the purpose of making this simple database adapter in the first place (although it was mostly just for fun anyway). Anyway, if anyone has any advice and knows of a simple means to achieve this goal that would be much appreciated. Thanks in advance This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=321386.0 Hi, I have an html page with multiple image tags inside it. I'm wanting to get the full URL of a specific image within that file. The specific image I'm looking for must start with 'http://www.mysite.com/images/' in the src part of the tag to make sure I'm getting the correct image. To find the occurence, I'm using strpos() to find the character position of the string match. What I then need to do is complete the rest of the URL to get the image name and then output this. So basically I need to get the string that comes after 'http://www.mysite.com/images/' and end when the speech mark occurs to close the src part of the image tag. This will then give me the full URL of my image. How do I do this? Or is there a better way to do this? Thanks. If I explode a string well using a substring when I implode that substring is now missing. for example. Code: [Select] $exploded = explode("[MAC]",$data); $data = implode($exploded); Now [MAC] would be missing in the $data string. any way to get around this? |
