PHP - Help Using Data From An Exploded Array This Should Be So Simple For Anyone Else

I keep having trouble with exploded arrays, every function i go to use within the exploded quotes requires a string not an array. Below im trying to count the spaces and if there are four or more change the data string to the halt string. The problem is most of the functions require a string, is there another way to only count the space characters within quotes without exploding the quotes?

Code: [Select]
$data = 'Hello World This is a test string!';
$halt = 'String had more than 4 spaces.';
$arr = explode('"', $data);
if (substr_count($arr, ' ') >= 4) {
$data = implode('"', $arr);
$data = $halt;

Hi, after banging my head against the wall for a while thinking this would be a simple task, I'm discovering that this is more complicated than I thought.

Basically what I have is a link table linking together source_id and subject_id.   For each subject there are multiple sources associated with each.

I had created a basic listing of sources by subject... no problem.   I now need a way of having a form to create an ordered list in a user-specified way.  In other words, I can currently order by id or alphabetically (subject name lives on a different table), but I need the option of choosing the order in which they display.  I added another row to this table called order_by.  No problem again, and I can manage all of this in the database, however I want to create a basic form where I can view sources by subject and then enter a number that I can use for sorting.

I started off looping through each of the entries and the database (with a where), and creating a foreach like so (with the subject_id being grabbed via GET from the URL on a previous script)
Code: [Select]
while($row = mysqli_fetch_array($rs)) {


//update row order
if (isset($_POST['submit']))  {

//get variables, and assign order

$subject_id = $_GET['subject_id'];
$order_by = $_POST['order_by'];
$source_id = $row['source_id'];


//echo 'Order by entered as ' . $order_by . '<br />';

foreach ($_POST['order_by'] as $order_by) {

$qorder = "UPDATE source_subject set order_by = '$order_by'
WHERE source_id = '$source_id'
AND subject_id = '$subject_id'";

mysqli_query($dbc, $qorder)
or die ('could not insert order');

// echo $subject_id . ', ' . $order_by . ', ' . $source_id;
// echo '<br />';
} 
}
else {
$subject_id = $_GET['subject_id'];
$order_by = $row['order_by'];
$source_id = $row['source_id'];

}

And have the line in the form like so:
Code: [Select]
echo '<input type="text" id="order_by" name="order_by[]" size="1" value="'. $order_by .'"/>

(yes I know I didn't escape the input field... it's all stored in an htaccess protected directory;  I will clean it up later once I get it to work)

This, of course, results in every source_id getting the same "order_by" no matter what I put into each field.

I'm thinking that I need to do some sort of foreach where I go through foreach source_id and have it update the "order_by" field for each one, but I must admit I'm not sure how to go about this (the flaws of being self-taught I suppose;  I don't have anyone to go to on this).

I'm hoping someone here can help?

Thanks a ton in advance

hi i am trying to make a payroll calculator script that takes employee info, calculates pay, displays submitted info in a table, stores info in an array, and updates the array when new info is submitted. i have most of these accomplished, i am having trouble with the "store into an array, and update the array when new info is submitted" parts of the project. i am still not very fluent in php so there may be easier ways to achieve what i have so far. any pointers would be a great help, this part has got me stumped.

Using curl_multi, I have loaded up 3 url's and then printed the array.

1) How can I also set a timestamp on output to let me know when each url was run?

2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( =>", "[1] =>", "[2] =>" and " )"? Code

<?php

function multiRequest($data, $options = array()) {

  // array of curl handles
  $curly = array();
  // data to be returned
  $result = array();

  // multi handle
  $mh = curl_multi_init();

  // loop through $data and create curl handles
  // then add them to the multi-handle
  foreach ($data as $id => $d) {

    $curly[$id] = curl_init();

    $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d;
    curl_setopt($curly[$id], CURLOPT_URL,            $url);
    curl_setopt($curly[$id], CURLOPT_HEADER,         0);
    curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1);

    // post?
    if (is_array($d)) {
      if (!empty($d['post'])) {
        curl_setopt($curly[$id], CURLOPT_POST,       1);
        curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']);
      }
    }

    // extra options?
    if (!empty($options)) {
      curl_setopt_array($curly[$id], $options);
    }

    curl_multi_add_handle($mh, $curly[$id]);
  }

  // execute the handles
  $running = null;
  do {
    curl_multi_exec($mh, $running);
  } while($running > 0);

  // get content and remove handles
  foreach($curly as $id => $c) {
    $result[$id] = curl_multi_getcontent($c);
    curl_multi_remove_handle($mh, $c);
  }

  // all done
  curl_multi_close($mh);

  return $result;
}



$data = array(array(),array());

$data[0]['url']  = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json';
$data[1]['url']  = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Black+Eyed+Peas&output=json';
$data[2]['url']  = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Nirvana&output=json';

$r = multiRequest($data);

print_r($r);

?>

Output

Array ( => Pearl Jam [1] => Black Eyed Peas
        [2] => Nirvana )

Preferred Output

01:00:01 Pearl Jam
01:00:02 Black Eyed Peas
01:00:03 Nirvana

Hi Everyone,

I have just started using Simple HTML DOM today and I have spent 4 hours not getting what I want.

I want to be able to extract the following information:

Code: [Select]
<div class="listing_content">
<span class="serialNumb" style="line-height: 21px;">77777</span>
<br />
444 ASDF, Alpha, Tango, Beta
<br />
77777 Director:99999
              <div>
<img title='web' src='http://cpgimg.com/images/icon_sm_web.gif' alt='web'/>&nbsp;&nbsp;<a href='javascript:void(0)' onClick="window.open('/redir.jsp?p_url=http:%2f%2fwww.cnn.com&p_cid=2707304&p_hid=279E00&p_ct=3527&p_pr=KO&p_fr=U');" class='listing_link'>website</a>&nbsp;&nbsp;<img title='email' src='http://cpgimg.com/images/icon_sm_mail.gif' alt='email'/>&nbsp;&nbsp;<a class='listing_link' href="javascript:void(0)" onclick="popupEmail('/email.jsp?lang=0&p_cid=2707304');(new Image()).src='/redir.jsp?p_url=&p_cid=2707304&p_hid=279E00&p_ct=3527&p_pr=ON&p_fr=E&msec='+(new Date()).getMilliseconds()">E-mail</a>&nbsp;&nbsp;
               </div>
</div>                                  
The content I need to pull separately from above include:
1- serialNumb = 77777
2- 444 ASDF, Alpha, Tango, Beta
3- 77777 Director:99999
4- www.cnn.com

I want all the data to recorded to different variables so I can upload them to MySQL.

Any help with this is much appreciated. I don't have to use Simple DOM HTML but per my search it seems to be the best tool (however, I am not so lucky with it.)

***Not to forget that this page is full of <div>, <br />, <img>, and other tags. The quoted part is just one excerpt but this part is unique and used once in the page "style="line-height: 21px;". Also the "('/redir.jsp?p_url" is also unique for the URL portion.

Thanks again.

I am just starting php and attempting a simple program that will retrieve some data from an array

I have 2 files one with the function containing the array, another with the code that should select a value from the array. I have done what I thought would work however it does nothing. Any help would be greatly appreciated

function.php
<?PHP
function getMonthName(){
    $a=array("one","two","three","four","five");
    print_r($a);
}
?>

retrieve.php
<?PHP
require_once('functions.php');
$number=3;

if ($number == $a) {
    echo "$a";
}
?>

I'm trying to learn arrays and I have this problem:

I have a variable $a which is a result from a  from a database query

If I echo it I get:
Code: [Select]
forenamesurnamedate_of_birthgenderpaypal_addresspayment_planaddress_line_1address_line_2address_cityaddress_zip_post_codeaddress_countrytelephonemobilewhere_did_you_hearreceive_newsletter If I var_dump($a) I get:
Code: [Select]
string(8) "forename" string(7) "surname" string(13) "date_of_birth" string(6) "gender" string(14) "paypal_address" string(12) "payment_plan" string(14) "address_line_1" string(14) "address_line_2" string(12) "address_city" string(21) "address_zip_post_code" string(15) "address_country" string(9) "telephone" string(6) "mobile" string(18) "where_did_you_hear" string(18) "receive_newsletter"
My question is, how do I get each value from a? It looks like an array to me because it holds multiple strings. I need to get the first, second and third elements printed on the page and used in other areas of my program.

Thanks in advance

I will state right here that I've never really delved into PHP before, but I'm prying apart the code on my site (a programmer made it for me). I've figured out how to add more checkboxes onto the page, but I've run into a problem.

Code: [Select]
'Artist' => array ( 'Cassiadawn', 'Cryptic', 'Diction', 'Glorfindel', 'Kyrislian', 'Russa', 'Ntkufreak', 'Taliba', 'Thunderbun', 'Velg', 'Lostdollie', 'Pookawitch') 

What I'm trying to do is replace  'Lostdollie', 'Pookawitch' with  'Lostdollie [R]', 'Pookawitch[R]'. How can I do this? I'd really appreciate any help anyone can give me! 

Hello.

I have a newbie question regarding arrays:

How can I echo an element's subsequent arrays and elements?

For example

Code: [Select]
$pers = array("Steve" => array("eyes" => "green", "age" => "43", "race" => "caucasian"));    



and if I echo $pers["Steve"] to make it display: green 43 caucasian.

Thanks.

Hello everyone,

I have a question with the use of the functon in_array... I have a list of categories in my table and I want to know if a specific category exists so I am doing this:

$categoriasexistentes= mysql_query("SELECT * FROM LugaresTuristicos WHERE DestinoPeg='$LinkDestino' GROUP BY  Clasificacion ")
      or die(mysql_error());
         
      $array = mysql_fetch_array($categoriasexistentes);

         print_r($array);

WHAT IS DISPLAYED BY print_r (there should be much more categories) IS THIS:

Array ( => Bar [Clasificacion] => Bar )


If I ad this all categories are displayed:

while($categoria = mysql_fetch_array($categoriasexistentes))

      {
         $todas=$categoria['Clasificacion'];
         
         ?>
          <?php echo"{$todas} - "; ?>
           
         <?php
         
         }; ?>

Hey guys I have an array and want to make it into a sting and separate each array segment by a comma...is there a function for this or should I just do it in a loop myself?...thanks
