PHP - Extracting A Value From A Array Using The Key

Hi all,

I hope someone can help me out here as I think I am close but am not sure where to go from here.  The problem is:
I have a cms where a user can see a list of photos in the gallery.
I provide them the ability to select what photos they want to appear on a particular webpage.
The problem I have is that the user wants to be able to put the photos in whatever order they choose.

So, I have a form (see attached), the html code is:

          <table width="566px" cellspacing="0" border="0">              <tr>
                <td width="33%">
                  <div class="serviceCell">
<input type='checkbox' checked='checked' name='photos[][0]' value='119' />&nbsp;Bathroom Sin...
<img src="./images/help.gif" title="Enter an integer to signify the order in which this image will appear on the webpage." alt="Enter an integer to signify the order in which this image will appear on the webpage."/>&nbsp;<input type="text" size="2"  name="photos[][1]" value="0"/>                  </div>
                </td>
                <td width="33%">
                  <div class="serviceCell">
<input type='checkbox' checked='checked' name='photos[][0]' value='113' />&nbsp;Courtyard 1
<img src="./images/help.gif" title="Enter an integer to signify the order in which this image will appear on the webpage." alt="Enter an integer to signify the order in which this image will appear on the webpage."/>&nbsp;<input type="text" size="2"  name="photos[][1]" value="0"/>                  </div>
                </td>
                <td width="33%">
                  <div class="serviceCell">
<input type='checkbox' name='photos[][0]' value='114' />&nbsp;Courtyard 2
<img src="./images/help.gif" title="Enter an integer to signify the order in which this image will appear on the webpage." alt="Enter an integer to signify the order in which this image will appear on the webpage."/>&nbsp;<input type="text" size="2"  name="photos[][1]" value=""/>                  </div>
                </td>
              </tr>...

Now, lets assume that the user ticked the box next to 'Courtyard 2' and entered an integer '1' in the input box to signify that this image should be displayed 1st on the chosen webpage.  These 2 values go into the multidimensional array (photoid, ranking) and are submitted in the form to php in the photos[][] array.

But here is where I have the problem.  I am trying to extract the values from the array and then do an insert to a table in mysql.  My syntax must be wrong somewhere so I am asking anyone to please offer any advice:

  if (isset($_REQUEST['submitted'])){   
       $photos = $_REQUEST['photos'];
...

    if(!empty($photos)){
       foreach($photos as $photoID){
         $sql = "INSERT IGNORE INTO menuItemPhotos
                SET photoid='$photoID[0]', menuItemid='$id', ranking='$photoID[1]'";
        $ok = @mysql_query($sql); // execute the query
      } // End of foreach($photos as $photoID){
    } // End of if(!empty($photos)){

Thanks

What I'm trying to do is take two arrays and combine them using array_combine. After they are combined I want to take each key and value pair and use them in a string to build a MySQL query. See below for some pseudo-code  =D


<?php
$fields = array('first_name', 'last_name'); //the fields that will be set with an UPDATE query.
$newvals = array('Joe', 'Blow');//The values that will go into $fields

$arr = array_combine($fields, $newvals);//Each value now has a key of the field it will update.

/**
This is where I want to return my SET string with something like 'SET ' . $arr['first_name']  ' = ' . $arr['first_name_value'] ', etc etc.
*/


There it is, I suppose. Are there any easier ways of doing what I'm trying to accomplish, that is, am I on the right track or just making things harder for myself?
Both arrays will have dynamic values throughout my application, so I need to be able to get both each field and value for each query. Any links to some constructs, etc, etc? That's all I really need and I can post the solution when I've figured it out.

I need to set up a threaded comments system in a PHP project and I got this script shown below from http://www.jongales....#comment-436261

class Threaded_comments
{
    
    public $parents  = array();
    public $children = array();

    /**
     * @param array $comments 
     */
    function __construct($comments)
    {
        foreach ($comments as $comment)
        {
            if ($comment['parent_id'] === NULL)
            {
                $this->parents[$comment['id']][] = $comment;
            }
            else
            {
                $this->children[$comment['parent_id']][] = $comment;
            }
        }        
    }
   
    /**
     * @param array $comment
     * @param int $depth 
     */
    private function format_comment($comment, $depth)
    {   
        for ($depth; $depth > 0; $depth--)
        {
            echo "\t";
        }
        
        echo $comment['text'];
        echo "\n";
    }
    
    /**
     * @param array $comment
     * @param int $depth 
     */ 
    private function print_parent($comment, $depth = 0)
    {   
        foreach ($comment as $c)
        {
            $this->format_comment($c, $depth);

            if (isset($this->children[$c['id']]))
            {
                $this->print_parent($this->children[$c['id']], $depth + 1);
            }
        }
    }

    public function print_comments()
    {
        foreach ($this->parents as $c)
        {
            $this->print_parent($c);
        }
    }
  
}

Here’s the example usage with the data provided as an array:

$comments = array(  array('id'=>1, 'parent_id'=>NULL,   'text'=>'Parent'),
                    array('id'=>2, 'parent_id'=>1,      'text'=>'Child'),
                    array('id'=>3, 'parent_id'=>2,      'text'=>'Child Third level'),
                    array('id'=>4, 'parent_id'=>NULL,   'text'=>'Second Parent'),
                    array('id'=>5, 'parent_id'=>4,   'text'=>'Second Child')
                );

$threaded_comments = new Threaded_comments($comments);

$threaded_comments->print_comments();

I have a sample select query that pulls data from a database and stores the result in the $comments array as shown below. The $comments array is then passed as an argument to the $threaded_comments object:

$sql = 'SELECT * FROM test_comments';
// submit the query and capture the result
$result = $conn->query($sql);
$comments = array();
while ($row = $result->fetch_assoc()) {
    $comments[] = $row;
}

The challenge is that nothing is printed to the screen when I run the script. Inspection of the comments array with the var_dump function is shown below:

array (size=4)
  0 => 
    array (size=3)
      'id' => string '1' (length=1)
      'parent_id' => string '0' (length=1)
      'text' => string 'comment' (length=7)
  1 => 
    array (size=3)
      'id' => string '2' (length=1)
      'parent_id' => string '0' (length=1)
      'text' => string 'comment' (length=7)
  2 => 
    array (size=3)
      'id' => string '3' (length=1)
      'parent_id' => string '1' (length=1)
      'text' => string 'comment ' (length=8)
  3 => 
    array (size=3)
      'id' => string '4' (length=1)
      'parent_id' => string '3' (length=1)
      'text' => string 'comment ' (length=8)

I was wondering if the array format from my select query is the issue? Could anyone provide a clue as to how to fix this?   Thanks.

HI guys,

I'm quite new to php, and I'm really struggling to get this right. I just cant get it to work properly.

Im trying to extract email from a list of URLS. I have currently got it to work with 1 URL at a time, but I am needing to as to how I can pass multiple URLS at once, either from a csv or just pasting them into the input.
any help would be much appriciated. here is my current code:

Quote

<?php



$the_url = isset($_REQUEST['url']) ? htmlspecialchars($_REQUEST['url']) : '';
?>

<form method="post">
  Please enter full URL of the page to parse (including http://):<br />
  <textarea name="url" cols="100" rows="10"><?php echo $the_url;  ?></textarea>
  <br />

  <input type="submit" value="Get Emails" />
</form>

<?php
if (isset($_REQUEST['url']) && !empty($_REQUEST['url'])) {
  // fetch data from specified url
  $text = file_get_contents($_REQUEST['url']);
}
elseif (isset($_REQUEST['text']) && !empty($_REQUEST['text'])) {
  // get text from text area
  $text = $_REQUEST['text'];
}

// parse emails
if (!empty($text)) {
  $res = preg_match_all(
    "/[a-z0-9]+([_\\.-][a-z0-9]+)*@([a-z0-9]+([\.-][a-z0-9]+)*)+\\.[a-z]{2,}/i",
    $text,
    $matches
  );

  if ($res) {
    foreach(array_unique($matches[0]) as $email) {
      echo $email . "<br />";
    }
  }
  else {
    echo "No emails found.";
  }
}

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

I usually only do design work, but a client wanted a log in system to his website, so I decided to do it.

I set everything up correctly, and users can sign up, login, and log out. However, he wants to be informed when a user logs into his site.

So say (user x) wants logs in, my client wants to receive an email with all of (user x)'s account information. How do I pull a row from mysql based on the login information provided?

My database is has 7 columns: user, pass, name, address, state, phone, email

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

hey guys i need to extract all the IP's of a string and loop them for more operations but for some reason i only get the first one

<?php

$string = '80.37.14.13 80.37.14.14 80.37.14.15';
preg_match("/\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/", $string, $matches);

foreach ($matches as $ip){
    echo "$ip<br>";
}

?>

The string is not really seperated by spaces ... it can actualy be messy and have ips rapped arround a lot of code. The regex works because i do get the first one ...

What did i miss?

Folks,

I want to extract the keywords Only form the below Script's output:


<?php
$keywords = file_get_contents('http://suggestqueries.google.com/complete/search?hl=en&gl=us&ds=pr&client=products&hjson=t&jsonp=ac_hr&q=paintball&cp=2');
//$keywords = json_decode($keywords);

print_r($keywords);
?>


Output is:

ac_hr(["paintball",[["paintballs","","0"],["paintball sniper","","1"],["paintball mask","","2"],["paintball vest","","3"],["paintball pants","","4"],["paintball bunkers","","5"],["paintball markers","","6"],["paintball chronograph","","7"],["paintball bow","","8"],["paintball helmets","","9"]],"","","","","",{}])

How to extract the keywords Only in an Array??

Cheers

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]
http://www.myvue.com/cinemas/index.asp?SessionID=0D86903A19334C93A7491563A77862A3&cn=1&ln=1&ci=66
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 =>
    array
      0 => string 'http://www.dailyinfo.co.uk/reviews/venue/1320/Vue_Cinema' (length=56)
  2 =>
    array
      0 => string 'Vue Cinema' (length=10)

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.
