PHP - Extracting Email From Url

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;

$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'm *attempting* to write a script that will take a paste of data from a user and when it's submitted it will drop certain parts of the data into databases and be available for recall later. I have the MySQL sorta out I think but I can't test until I get this part done.

Basically people will paste a copied paste (CTRL A, CTRL C and go to my form and just hit CTRL V). It will contain a bunch of data I want to drop in the database but in different areas, like the following example the items in bold are the items I want to grab.

First Name: Lincoln
Last Name: Coe
Address: 1234 Easy St, Perfectville, PV 00000
Telephone: 0000000000

Hi there

I need to extract data from some XML. I have found a few sites that explain that part to me, however there is a section of the data which I need to extract and am not sure how to go about it. Below is an extract of the XML, the section I am trying to extract is highlighted in red (it is essentially a text message being sent I am trying to get the contents of the sms/text message):

 <usa_smpp_host>THTTP</usa_smpp_host>
 <short_message>id:660352946 sub:001 dlvrd:001 submit date:1102081032 done date:1102081035 stat:DELIVRD err:000 text:Test SMS message</short_message>
 <dest_addr_npi>1</dest_addr_npi>

Any assistance would be appreciated. Have played around quite a bit but have not managed to figure it out yet.

thanks

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!!!

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.

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>';
?>

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?

Cheers

I've only been studying PHP for a week now and have come across this problem which I'm sure there is a simple answer to, but I just can't figure it out and would appreciate some help. I've spent far too long on this minor issue already!

I have a table which contains a list of products, in this case books, which stores the date when each new item is added.
I have a query that then searches through this table and extracts the 6 most recent additions.

Here is the code I have so far:

Code: [Select]
$sql = mysql_query("SELECT * FROM products ORDER BY date_added DESC LIMIT 6");
$productCount = mysql_num_rows($sql); // count the output amount
if ($productCount > 0) {
while($row = mysql_fetch_array($sql)){
             $id = $row["id"];
$title = $row["title"];
$author = $row["author"];
$price = $row["price"];
$date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
$dynamiclist .= //My table showing the products
}
} else {
$dynamicList = "There are currently no Books listed in this store";
}
This works well when I need to display the 5 most recent products in a normal table fashion, one below another, on the page.

However, I want to display the products in a more personalised order. For example display the newest item in one section of the page and 3rd newest in another.

What is the best way to select an individual row from a query? To extract the details of the 2nd newest item to display in the header, for example.

Thanks for your help.

Hi!

I have .swf files that have images in them. I can view them with swf decompiler on my computer but i need to have this functionality on my website. Is there any way to extract images from .swf file with php?

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));

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>");
?>
