Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

Cheers,

Thread: Sorting multidimensional arrays

    Sorting multidimensional arrays

    Does anybody know how to sort multidimensional arrays? I followed the instructions on the book PHP and MySQL Web Development but it doesn't seem to work. The instructions are here:
    http://www.samspublishing.com/articl...&seqNum=6&rl=1

    Any other methods?

    Thanks in advance,

    Leo

    Hey, thanks, i didnt know that function existed. I already read about it at the php site and tried a couple of examples, but I just can't get my code to work properly. I dinamically create an array, like this...

    PHP Code:
    $count 0;
    $handle opendir($dirEstate);
    while((
    $file readdir($handle)) !== FALSE) {
        if (
    is_dir($dirEstate $file)) continue;
        if (!
    eregi(".xml$"$file)) continue;
        
        
    $estateFile simplexml_load_file($dirEstate $file);

        if(
    $count == 0){
        
    $sortArray = array($sortArray2=array($estateFile['id'],
            
    $estateFile->mainphoto,
            
    $estateFile->address,
            
    $estateFile->city,
            
    $estateFile->state,
            
    $estateFile->zipcode,
            
    $estateFile->price,
            
    $estateFile->category,
            
    $estateFile->forlrs,
            
    $estateFile->pubdate)
            );
            
    $count++;
        }else{
            
    array_push($sortArray$sortArray2=array($estateFile['id'],
            
    $estateFile->mainphoto,
            
    $estateFile->address,
            
    $estateFile->city,
            
    $estateFile->state,
            
    $estateFile->zipcode,
            
    $estateFile->price,
            
    $estateFile->category,
            
    $estateFile->forlrs,
            
    $estateFile->pubdate)
            );
        
    $count++;
        }
    }

        
    array_multisort($sortArray[0], SORT_DESCSORT_STRING,
                        
    $sortArray[1], SORT_ASCSORT_NUMERIC);

        
    var_dump($sortArray); 
    And I get a result like this:

    PHP Code:
    array(2
        {
        [
    0]=> array(10
        { [
    0]=> object(SimpleXMLElement)#17 (1) 
        
    { [0]=> string(4"rent" } [1]=> object(SimpleXMLElement)#24 (1)
        
    { [0]=> string(36"realestate20070213101812_5_thumb.jpg" } [2]=> object(SimpleXMLElement)#33 (1)

    { [0]=> string(10"2007-02-13" } [9]=> object(SimpleXMLElement)#23 (1) 
        
    { [0]=> string(11"100 Main St" }
        }
        [
    1]=> array(10
        { [
    0]=> object(SimpleXMLElement)#32 (1) 
        
    { [0]=> string(4"sale" } [1]=> object(SimpleXMLElement)#28 (1) 
        
    { [0]=> string(34"realestate20070213102231_thumb.jpg" } [2]=> object(SimpleXMLElement)#25 (1) 
        
    { [0]=> string(24"realestate20070213102231" } [3]=> object(SimpleXMLElement)#35 (1) 
        
    { [0]=> string(5"Texas" } [4]=> object(SimpleXMLElement)#29 (1) 
        
    { [0]=> string(6"Laredo" } [5]=> object(SimpleXMLElement)#31 (1) 
        
    { [0]=> string(4"Home" } [6]=> object(SimpleXMLElement)#38 (1) 
        
    { [0]=> string(6"120000" } [7]=> object(SimpleXMLElement)#30 (1) 
        
    { [0]=> string(5"78045" } [8]=> object(SimpleXMLElement)#44 (1) 
        
    { [0]=> string(10"2007-02-13" } [9]=> object(SimpleXMLElement)#37 (1) { [0]=> string(15) "10100 Center Rd" } } } 
    I want my array to be sorted by price. I already tried changing the values between the brackets and I already tried other things, but I can't get it to work.

    Can anybody give me any suggestions?

    Thanks in advance,

    Leo
