PHP - Help With Array To String Conversion

Hello,
I'm going to be sending emails to users from a community calendar showing events for the day or a time frame specified elsewhere.  The problem I'm having is turning results of DB query into a string when there are multiple results for the day.  It works just fine with single results.  I understand why it doesn't work but can't figure out how to solve the problem.  Don't worry about the $eventdate as that comes from the same array as the $event_id used to call the array shown below.  I tried foreach and implode but couldn't get it working so I'm starting over and asking for your guidance on how is the best way to pull this off.  Thanks for your help.


Code: [Select]
$getevent = mysql_query("SELECT title, description from ".$conf['tbl']['events']." WHERE event_id=$event_id AND private=0");
WHILE ($gtevent = mysql_fetch_array($getevent)) {
$event_title=$gtevent['title'];
$event_description=$gtevent['description'];

$message="<p><span style=\"font-size:24px\">$event_title</span><br />$eventdate</p><p>$event_description</p>";

}  

	<?php
    $srs = array();
    for ($section = 1; $section < 5; $section++) {
        for ($row = $section; $row < 10; $row++) {
            for ($seat = $row; $seat < 20; $seat++) {
                $srs[] = array(
                    'section_name' => $section,
                    'row_name' => $row,
                    'seat_name' => $seat);
            }
        }
    }
	
    output(convert_array($srs));
	// Converts the array
    function convert_array($input)
    {
	        return $input;
    }
	    function output($obj)
    {
        echo "<pre>";
        print_r($obj);
        echo "</pre>";
        die;
    }
?>
	

I'm trying to convert those array number to string, add implode() to make it happen, but seem PHP didn't recognize variable in $input. Like this implode("Section: ", $input) or (Section: ", $srs). Can you help me?

Thanks,

Gary

I need to assign unknown array keys and their values to strings.

The code I am using is:
Code: [Select]
$cart = $_SESSION['cart'];
$items = explode(',',$cart);
$qty = array();


foreach ($items as $item) {
$qty[$item] = $qty[$item] + 1;
}
print_r($qty);
The keys change and are not ordered. I do not know what the key or it's value may be.  So as an example, I might have:
Code: [Select]
Array ( [2] => 5 [4] => 8 ) or in a different scenario, I might have:
Code: [Select]
Array ( [1] => 6 )
What those numbers represent is a product id (the key), and the quantity (the value of the key).

Can someone help me to assign these to a string?  I have been reading all morning, and not making any progress. 

Thank you!

I want to echo the last two (or at least the last) string of an array. What is the simplest way to do so ?

Hi everybody,

I need some help about how to convert string to array name. I have the following function which pass $_REQUEST type as parameter. It is not working because I don't know how to convert $method to $_GET or $_POST in a proper way. Do anybody know how?

Code: [Select]
function validateIfFilled($method, $fields)
{ 
    $exploded=explode(",",$fields);   
    foreach($exploded as $field){                             
        if(empty($method[trim($field)])){         
          return false;     
        }
    }
    return true;
};

if(!validateIfFilled('$_GET', "email, password, address"))
...
Thank you!

Hello
I am facing a problem which i can not handle. I appreciate for any help.

My Database is:
Code: [Select]
CREATE TABLE IF NOT EXISTS `shops` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `options` text,
  `user_name` varchar(250) NOT NULL ,
  PRIMARY KEY (`id`),
  UNIQUE KEY `user_name` (`user_name`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 COMMENT='user data stored' AUTO_INCREMENT=1 ;
And some sample data as below:
Code: [Select]
INSERT INTO `users` (`id`, `options`, `user_name`) VALUES
(1, 'apple-orange-grape-bmw-toyota-fig-', 'user1'),
(4, 'apple-tomato-pc-notebook-yellow-', 'user2'),
(5, 'blue-green-orange-cdrom-', 'user3'),
(6, 'orange-yellow-blue-pink-bread-', 'user4');
How can i display how many apples or green or any item selected by user?
So far i tried in_array, array_count_values but seems no one is working.

Hello,

I have a string that contains a directory path much like: "/images/icons" and I want to take that string through a function and explode it into an array of directories that with add my directory structure array:

images icons
Then if I were to send the string "/data/documents" to the function it would append to the existing array:
images icons data documents
Here's the code that I've got thus far:
<?php

$global_structure = array();

generate_structure("./images/icons");
generate_structure("./data/documents");

function generate_structure($directory)
{
    if(!is_dir($directory))
        return false;

    $directory_structure = explode("/", $directory);

    // do something here to iterate over $global_structure and add new directories to equal to current directory path making the value an empty array.
}

?>

Hi,

Help me please:





// Build View Array
    if ($view_result!=false) {
        $i=0;
        while ($view_row =@ mysql_fetch_array($view_result)){

            $view_rows[$i] = $view_row;

            // build view_comments array
            if ($viewcomments=="yes") {
                $sql = "SELECT * FROM blog_comments WHERE nBlogId=".$view_row["nIdCode"]." ORDER BY nIdCode DESC";

                $result = mysql_query($sql,$con);

If I wanted to print a string that contains a variable that also contains an array, how would I do so? I want to put the resulting echo into a log file.

Example: “These are the books: $userArray and these are the pages: $pagesArray”;

With just an array, I can use print_r($array, true) to get an array formatted for use in a string (which works well for my purposes) but this doesn’t work with two arrays unless I do this manually. (Such as setting the $user_array = print_r($userArray). But I want to write a function that will take a string, potentially containing arrays  (as variables), and interpolate/make them legible for  humans. (Some of the arrays are also multidimensional.)

But it looks like I can't even concatenate a string and an array. $string = $string . $array. gives an error, array to string conversion.


I don’t understand PHP very well so please explain what is going on here. and the best way to record something like the Example above.
 

Hello,

I'm having trouble getting a piece of code to work and as a result right now i have bloated code on a simple task.  Currently my code looks like this:

Code: [Select]
//convert responses into one string to check for spam
$full_string = $name.' | '.$email.' | '.$message;
//look for spam words
if ( (stristr($full_string, 'test')) || (stristr($full_string, 'http')) || (stristr($full_string, 'www')) || (stristr($full_string, 'site')) || (stristr($full_string, 'fake')) || (stristr($full_string, 'viagra')) || (stristr($full_string, 'cialis')) || (stristr($full_string, 'asdf')) || (stristr($full_string, 'txt')) || (stristr($full_string, 'doc')) || (stristr($full_string, 'xls')) || (stristr($full_string, 'htm')) || (stristr($full_string, 'sale')) || (stristr($full_string, 'free')) ){

I would like to instead place all my 'spam' words in an array like this
Code: [Select]
$spam_array = array('test', 'viagra', cialis...etc
If i had all my spam words in an array, how would i write an if statement to check if any of those words appeared in $full_string ?

Thanks for your help!

Dead simple, I know it is but I'm still a little newbie. I have this chat box, and I don't want people to be able to swear in it so I need help making a function where you call the string as an argument and it returns true if the string has any words from an array in it, Even if the word is walking and not just walk. If it's true I can replace the entire string with something else.

Can someone tell me what functions I need? I prefer you didn't do it all for me I need to learn 

Thanks in advance!

This is my code for displaying images from a folder:    function generate_img ($imagepointer, $imageornot){
 if($imageornot == 1){
 $var = getcwd();
 $dirlocation = $var."\\imageuploads\\".$imagepointer;
 $files = array_diff(scandir($dirlocation), array('..', '.'));
 foreach ($files as $image){
 $data[] = array('label' => '<img src="/imageuploads/'.$imagepointer.'/'.$image.'" alt="thumbnail"> <br/>');
        };
    return $data;
    }
    else {
    return FALSE;
    }
 }   I'm using it with print_r:               <p><?php print_r(generate_img($imagepointer, $imageornot)); ?></p>     Working ok, but obviously not good for a live site. Is implode() a good idea in this situation? And how would I use it?

Appreciated.    

I have a variable and it contains a lot of strong data would I want to convert the string data into an array. What's the best way of doing because I know older versions of php will be slightly different?
