PHP - Extracting From Url

$example "Q: Example? A:"

Let's assume that I'd like to display $example but exclude "Q:" and "A:", how would I do that?

I have an RSS feed, with alot of data of lottery numbers.

the feed itself is : http://www.alllotto.com/rss/NY/latest.rss

The item i am interested in is:

Quote

<item>
                   <title>Take 5</title>
                 <description>2011-08-27: 4, 10, 16, 17, 31</description>
                   <guid isPermaLink="false">USA-New-York-Take-5-2011-08-27</guid>
                 </item>



How could I output those to varibles?

thanks

Hey guys i have a array i made and im wanting to grab a random value out of the array.
The only way i can see to do this looking at the list of array functions is i need to random a key first?
and then return the value assigned to the random key i just generated?
I only see a function that lets me do the opposite. array_search()

so now that i have generated a random key how do I grab just the value from the array using the random key. or is there a function i can just random value?

$explode_names = explode(" ", $planet_names);

$random_key_name = (array_rand($explode_names, 1));


echo $random_key_name;

I'm wanting to extract an image from an external website and save to a location on my web server automatically.

The scenario:

1. A user has an order form on our website with a field to paste the URL of a website in;
2. The user visits an external website page, which includes an image;
3. The user copies the URL out of the address bar, goes back to our website and pastes the link into the order form;
4. The user clicks next, and this extracts the image from the external website and uploads it to our website so the image can be seen alongside the order.

My questions a

a. Can this be done?
b. If it can't physically download the image and copy to my web server, can I read the html source of the external website and grab the full URL to use to show the image on my website?

Thanks for your help.

I have a string that looks like /index.php?g1=111&g2=222&g3=333.  How can I obtain the value of g1 (i.e. 111)?  It does not represent the current state of the server thus I cannot just use $_GET.  It also is not necessarily the first item.

The script below appears to work, however, http://php.net/manua...n.parse-url.php states
  This function is intended specifically for the purpose of parsing URLs and not URIs. However, to comply with PHP's backwards compatibility requirements it makes an exception for the file:// scheme where triple slashes (file:///...) are allowed. For any other scheme this is invalid.  
It appears that my string is a URI and not a URL, but I might be wrong.

How should this be accomplished

<?php
$str='/index.php?g1=111&g2=222&g3=333';

$array=parse_url($str);
parse_str($array['query'],$get);
echo("<p>{$get['g1']}</p>");
?>

hey guys im wondering how you would add or takeaway a hour from a timestamp in a database when trying to select it please?   thank you

Hi

Ive been trying to solve this problem for a few hours but am having no luck so would appreciate any help

Im looking for a function/way of extracting info from a dropdown list when a form is submitted. The form field has a name and email address i.e John (john@smith.com) and i just need the email address part to submit into a mysql database.

I tried using the explode() function but this didnt work.

Any ideas?

Hi, not sure if this is posted in the right place (think it should be in the Regex section  ) but hopefully someone can help me out a bit.

I have the following string for example which is stored in a variable called $var.

Quote

This is a reference [ref=17][/ref] number


I wish to extract only the number after the equals sign and store it as a variable. So I am using the following code to do so:

$ref_num = preg_replace("/.*?\[ref\=(.*?)\]\[\/ref\].*?/is", "$1", $var);

The only problem is, I can omit the text before the integer and the tags themselves but I still get the text after the [/ref] section and I cannot get rid of it. It seems my .*? placed after it doesn't work like it does at the beginning.

Can anyone offer any help at all, it will be greatly appreciated - I'm fairly new to using Preg_replace so I still don't know how best to form Regular Expressions.

Thanks, Dan


EDIT-
I have found a workaround which I will post below - however I would still like to solve it the way I planned originally which is the way I posted here. Here's what I did - because I know the integer is never going to be more than 5 characters long, I used the replace from before but added a substring like so.

$ref = substr(preg_replace("/.*?\[ref\=(.*?)\]\[\/ref\]/is", "$1", $var),0,5);

This grabbed the first 5 characters whether it was a number or not, then I used this to strip any non-numerical characters. Finally I added an intval to convert it to an integer rather than a string.

$ref = intval(preg_replace ('/[^\d\s]/', '', $ref));

Morning all,

I am wondering whether there is a way (I am sure there is!) to extract the full website address with any GET variables in it also.

Basically, I am trying to extract the website address and add another $_GET['var'] to it.

Something like.

example web address:  http://www.website.com/index.php?type=abc

<?php
$address = // Extract the current website address here.
$newvar = "?model=123";
$link = $address.$newvar;

echo '<a href="$link">Click here to add a variable</a>';
?>

I'm normally fairly proficient with PHP, but I haven't done any coding in quite a while, so I'm a little rusty.

I have an entire page of text from which I need to extract a single value. Here is a small portion of the page in question:

Code: [Select]
Total Rank: 128
Total Points: 4,978
Next Rank: 20

For instance, I need to extract the values "128" "4978" and "20" and store them in variables. These values change all the time, so I'm not sure what the best way to go about this is... maybe a regular expression  ? If that's the case, I've never been too good with them, so any help would be appreciated.

I have a string

Code: [Select]
<p>Bollywood romcom: a pair of wouldbe suicides choose the same bridge at the same time.</p><p><a href="http://www.dailyinfo.co.uk/reviews/venue/1320/Vue_Cinema">Vue Cinema</a> (<a href="http://www.myvue.com/cinemas/index.asp?SessionID=0D86903A19334C93A7491563A77862A3&cn=1&ln=1&ci=66" target="_blank">www.myvue.com/cinemas/index.asp?SessionID=0D86903A19334C93A7491563A77862A3&cn=1&ln=1&ci=66</a>), Ozone Leisure Park, Grenoble Road (next Kassam Stadium), Oxford OX4 4XP; Tel. 08712 240 240 (10p per min from BT).<br /> </p>
Using php i want to extract

Code: [Select]

from the <a> tag.

I have already tried using

    
<?php

$pattern = "/<a href=\"([^\"]*)\">(.*)<\/a>/iU";
preg_match_all($pattern, $link, $matches);
var_dump($matches);
?> 

The output I get is

array
  0 =>
    array
      0 => string '<a href="http://www.dailyinfo.co.uk/reviews/venue/1320/Vue_Cinema">Vue Cinema</a>' (length=81)
  1 =>

      0 => string 'http://www.dailyinfo.co.uk/reviews/venue/1320/Vue_Cinema' (length=56)
  2 =>

      0 => string 'Vue Cinema' (length=10)

Hi there,

In my attached PHP script, I extract text between two strings in the input file and write the extracted text to an output file.  Everything seems to work fine, except I can't figure out how to include the row that says "Richland" (after the row that says "Creighton") in the extracted text. 

If someone could guide me how to do this, I'd greatly appreciate it.  The PHP script is attached.  The input file is in htm format and I can't attach that here so I will provide a link to the file I'm calling: http://www.afws.net/data/pa/savedata/109/06/2009060920.pa.htm

Many thanks!!!

Hi guys,
This is my problem:
I have a csv file let's say have these values:

blue,1,2,3,4
red,8,5,6,7

I need to add thes values into a 2d array
to be able to use like this:
colors[1][2]=2
colors[2][4]=7

Where my first number is the row and the second number is the value within that row.

This is what I got so far

<?PHP
$i=0;
$j=0;
$file_handle = fopen("color-list.csv", "r");
while (!feof($file_handle) )
   {
   $colors = fgetcsv($file_handle, 10000);

for ($j=0; $j<=4; $j++)
               {
               $row[$i][$j]=$colors[$j];
                                        print row[$i][$j];
               }
$i++;
?>

For some reason this doesn't work. Maybe I am declaring the arrays wrong.

Thank you!

Hi - I have an array where one of the values delivers a string. Here is the output from a print_r($pickupdates):

Code: [Select]
Array
(
    [0] => Array
        (
            [location] => Clearwater
            [TheDates] => 1311746700,1321746641,1331668779
        )

    [1] => Array
        (
            [location] => Canmore
            [TheDates] => 1311746700,1321746641,1331746641
        )

    [2] => Array
        (
            [location] => Collingwood
            [TheDates] => 1311746700,1321746641,1331746641
        )

    [3] => Array
        (
            [location] => Varsity
            [TheDates] => 1321746641,1330746700,1331746700
        )

The challenge is to get the location and TheDates  into a nice HTML table which would look like this:

Code: [Select]
LOCATION          DATE 1            DATE 2              DATE 3

Clearwater         April 1              May 1                June 1

Varsity               April 2              May 2                June 2

Collingwood        April 3              May 3                June 3


Canmore        April 4              May 4                June 4


Ok - Now I am stuck, I need to be able to uniquely identify each date that is associated with the location such that I can run a foreach() on then so I can populate the table properly. I tried using list() and explode. List does not separate the dates and explode needs a string not an array.

I'm really stuck - a very big Heartfelt thanks to anyone who can steer me in the right direction.

MANY THANKS !
