I'm not sure why you changed all this.
All you have to do is a simple foreach loop with a counter, and
break when the counter reaches your condition:
$need = 5; /* how many we want */
foreach($this->_content as $index => $item) {
if ($item['type'] == 'item') {
//...
/* only decrement if its an 'item' */
$need--;
}
if (! $need) break; /* we got everything we needed */
}

Re: [PHP] Putting a stop in a foreach
Hmm, yes I see. Thank you.
I guess what I should look at then is getting the key value (internal
counter/pointer) in the array going to the foreach. Like this example...
$a = array( 1,2,3,17 );
$i =0;/* for illustrative purposes only */
foreach ( $a as $v ) {
echo "\$ a[$i ]=> $v. \n ";
$i ++;
}
Once I have that key value (internal counter) I should be able to do
something with it? What I really want to do (since I can't easily get at the
query building the array being passed to the foreach) is get the foreach to
stop outputting results at a certain limit.
Thanks again,
Verdon

[PHP] Putting a stop in a foreach
Hi :)
I'm trying to put a stop in a foreach statement following the user
suggestion here, php.net/manual/en/control-structures.foreach.php
Not really knowing what I am doing, I am running into some synatx problems.
I'm sure I'm doing something really stupid, can anybody point it out?
This is the original statement that works...
foreach ($this->_content as $item) {
if ($item['type'] == 'item'){
$elements['ITEM_LINK'] = $item['link'];
$elements['ITEM_TITLE'] = $item['title'];
$elements["TARGET"] = $this->_target;
$items .= PHPWS_Template::processTemplate($elements,
"phpwsrssfeeds", "block_item.tpl");
}
}
This is my attempt to count items and put a stop in the foreach so it only
returns 5 items.
foreach ($this->_content as $n => $item) {
if ($n=="5") {
break;
} else {
if ($this->_content[$n] => $item['type'] == 'item'){
$elements['ITEM_LINK'] = $this->_content[$n] => $item['link'];
$elements['ITEM_TITLE'] = $this->_content[$n] => $item['title'];
$elements["TARGET"] = $this->_target;
$items .= PHPWS_Template::processTemplate($elements,
"phpwsrssfeeds", "block_item.tpl");
}
}
}
Php doesn't like the syntax on any of the,
$this->_content[$n] => $item['type']
, etc lines
TIA,
Verdon
