PHP - Php Manual Has A Confusing Piece Of Code For Passing By Reference..

Rules:
1) It has to be legit and actually work and have a useful function in society/web world.
2) The code cannot be minimized into one line. It has to have line breaks. (Not necessarily for each new function or short hand property, but so it's partly readable)
3) It has to be written in PHP or Javascript.


For example, (Not my original code) but I'll start: A time_ago function:

function timeago($tm,$rcs = 0) {
    $cur_tm = time(); 
    $dif = $cur_tm-$tm;
    $pds = array('second','minute','hour','day','week','month','year','decade');
    $lngh = array(1,60,3600,86400,604800,2630880,31570560,315705600);

    for($v = sizeof($lngh)-1; ($v >= 0)&&(($no = $dif/$lngh[$v])<=1); $v--); if($v < 0) $v = 0; $_tm = $cur_tm-($dif%$lngh[$v]);
        $no = floor($no);
        if($no <> 1)
            $pds[$v] .='s';
        $x = sprintf("%d %s ",$no,$pds[$v]);
        if(($rcs == 1)&&($v >= 1)&&(($cur_tm-$_tm) > 0))
            $x .= time_ago($_tm);
        return $x;
    }

Your turn!

Helo dear people,

I need some help with piece of code that generates XML
This all works as is:

Code: [Select]
include(dirname(__FILE__).'/config/config.inc.php');
require_once(dirname(__FILE__).'/init.php');

error_reporting(0);
$p=Product::getProducts(7, 0, 0, 'id_product', 'desc', false);
$products=Product::getProductsProperties(7, $p);

header("Content-Type: text/xml\n\n");
//print "Content-type: text/html\n\n";
echo '<?xml version="1.0" encoding="utf-8"?>

<Catalog>';
foreach ($products as $row) {
if ($row['active']){

$img=Product::getCover($row['id_product']);
echo '
<products>
    <code>'.str_replace("&", "&amp;", $row['id_product']).'</code>
    <name>'.str_replace("&", "&amp;", $row['name']).'</name>
    <descr>'.str_replace("&", "and", strip_tags($row['description_short'])).'</descr>
    <price>'.($row['price']*1).'</price>
    <quantity>'.str_replace("&", "&amp;", $row['quantity']).'</quantity>
    <categ>'.str_replace("&", "&amp;", $row['category']).'</categ>
    <link>http://www.xxxxx.hr'.$row['link'].'</link>
    <img>http://www.xxxxx.hr/xxxxx/'.$shopUrl.'img/p/'.$row['id_product'].'-'.$img['id_image'].'.jpg</img>
</products>';
}
}
echo '</Catalog>';
?>code]

 :shrug:
But now i need to hide quantity if its larger that 5 pieces.
So that all quantity that is >= equal or larger of 5 si shown in XML as 5.

Can anyone help me out with this!?

I have the below code:

Code: [Select]
$buttons = "button+='<table height=\"40\" border=\"0\"id=\"table1\"cellspacing=\"0\"cellpadding=\"2\"><tr><td>---PLACE CODE HERE---</td><td valign=\"bottom\">';\n";
between the to cell tags (<td>---PLACE CODE HERE---</td>) I need to add this code:

Code: [Select]
document.getElementById('com').innerHTML=<?php echo $gSurfMultiLoadedText; ?>+button2;
My problem is the '; " and \" stuff Anyone care to show how I can merge these pieces?

I have this little code that I cannot get to work
Code: [Select]
$sql_buildings = ("SELECT castle, treasury, huts, [b]leader_id[/b] FROM teams WHERE team_id=[b]".$_GET['t']." [/b]");
$rsbuildings = mysql_query($sql_buildings);

if($rsbuildings[".$_GET['t']."] == 'leader_id' ){
The problem is this part:
Code: [Select]
if($rsbuildings[[b]".$_GET['t']."[/b]] == '[b]leader_id[/b]' ){
How can I write it to have these to values work?

Parse error: parse error, expecting `','' or `';'' in C:\xampp\htdocs\sources\admin\manage-user.php on line 26
Sorry, im a noob when it comes to coding. please help!

I am past a beginner in php but no where near an expert and I need some help. This piece of code he

 $query .= " limit $s,$limit";
  $result = mysql_query($query) or die("Couldn't execute query");

is part of my search results page with paged indexes (next, previous 10, etc.). However with this code i get the die message but if i take the first line off ($query), the page executes but then the page doesn't operate correctly i.e. shows 15 results when the $limit(limit for rows) =10. Is it not written correctly or am I missing somethingwith the top line?

if the entire script is needed let me know and i will paste it? Thanks in advance for any help!

hello

how do i pass a foreach loop through "Passing by Reference"

say i have a foreach loop in a function like this:

Code: [Select]

function findText(&$output){
  $word = Text::find_all(); 
  foreach ($word as $words){
  $output = $words->text;
  }
}

then one the page i put

Code: [Select]

findText($output);
echo $output;


that will just give me the last word in the database.

so how do i get it to echo out the array on the page ?

thanks

Hello,   I'm working on a project that requires me to have stock / fake demo files that will be replaced with real files provided by users... I need something to take space and then when people actually start using the site and inputting data, then I can replace each file with new, unique files.   I have some idea of how this would work. I would need incremented or non-matching identifiers and then a script that probably works on an if statement    like   If new data, take first list of data, delete, replace with new data. Something like that. 

I have learned php coding by doing (looking for patterns and trying things) and I have hit a roadblock trying to modify a template that creates a delimited text file of products from an ecommerce site (Sunshop) for upload to google base. I have tried to search for the answer but I don't know what I don't know so I may not have put the right search terms in.  So I apologize if this has been addressed in the past.

  The script uses case to call up the contents of specific rows of the product table which I understand but in when I want to call up the manufacturer row Sunshop uses a reference number and then a different table called manufacturers with an ID row that matches the manufacturer row numbers (that are associated with each product) and then next to it a name row which contains the actual manuracturer names.  Can I put code in the case that will pull up the referenced name as opposed to just the numbers that are in the column?

This is what I have now that just calls up the cells from the manufacurer row:

Code: [Select]
case 'mfg': $item[mfg] = $item[manufacturer];
The mfg refers to this part of the code in an array:

Code: [Select]
array('header' => 'manufacturer', 'value' => 'mfg'),

In case it helps I will attach the full document.  Thanks.

<?php
$pageTitle='Edit Profile';
require_once ("header.php");
?>

How can I pass a variable like that through header.php?  I know it doesn't work the way I have it.

Ok, so first off, here is how the tables are setup:

Cars_Table | ID, CatID
Categories_Table | ID, Parent_ID, Name

Now, both parent categories and sub-categories are in the same table. the C_Table.CatID shows only the sub-category the item is in. How would I make a list of the distinct names of Parent category names (those with Parent_ID = 0) in ASC order, but I want to only pull the parent categories for which there is an item associated. Essentially, the makes and models of the cars are stored in the same table, the Makes are the ones with Parent_ID = 0 and the Models also have parent ID's. The Cars_Table.CatID only shows the Model ID. I'm still fairly new to PHP and this one is really confusing me O.o

Everytime I test my page, I seem to get a parse error, in which I have tried to identify the problem but I am stumped as to what it is.

This is the error...
Code: (error) [Select]
Parse error: syntax error, unexpected '}' in C:\xampp\htdocs\drew\film.php on line 21
The php code (lines 21-24 relevant to the error) are below...
<?php if($flm == "73d0" || $flm == "9017" || $flm == "c3a2") {$pass = 1}else {$pass = 2} ?>
<?php if ($pass != 1) { ?><meta http-equiv="refresh" content="0;url=/drew/"><?php }else { ?>

<?php echo "hello"; } ?>

If you could help, thanks in advance.

I was wondering if you loop through an array and in the foreach() you specify an if statement that unsets certain items from the array, if those get unset from the original loop. Probably doesn't make much sense so heres an example

Code: [Select]
<?php
//say there are 3 items in the $parent array
//say there are 10 items in the $items array

//say only the second item in the $items array value_one equals "abcd"

foreach($parent as $id => $value)
{

foreach($items as $key => $value)
{

      if($items[$key]['value_one'] == "abcd")
      {
            unset($items[$key]);
      }
}

}
?>
So on the first item in the parent array, all 10 items would be cycled through. On the second second item of the parent array, all 10 items would be cycled through and the one item that has value_one == "abcd" would be unset. So on the third item of the parent array, am i correct in assuming only 9 items would be cycled through because there would be only 9 items in the $items array?
