I have and array of numbers which I can retrieve as follows:

foreach ($this->items as $item) 
 $this->something += ($this->dels[$item]) ;

what this does is adds all the $this->dels[$item] values up, however I would like to get the highest value from this and then use it. I have tried the following:

foreach ($this->items as $item) 
 $this->something = max($this->dels[$item]);

however this returns $this->something = 0
any help welcome

  If you want the maximum of the array - no need for a loop just $this->something = max($this->dels) ;

  @Ria Why are you doing max($this->dels[$item]) ? Does $this->dels[$item] itself contain an array?

  “however I would like to get the highest value from this and then use it” - use it for what? Your description of what you are actually trying to achieve here is more than unclear. Using max inside that loop probably makes no sense whatsoever though.

It turns out that the following works:

foreach($this->items as $item) 
 $something[] = $this->dels[$item] ;

 
 $this->something = max($something);

Thanks for looking
