Can't use function return value in write context

[bazianm]

Hi,

 

I am kind of new to php (although an experienced programmer in other languages). I am working on an application and I have a problem which I have been unable to figure out. I have googled it and still cannot get a handle on it. I have boiled it down to a simple example. Here's the code:

 

<?php

$array = gettest();

foreach ($array as $item)
{
if(gettype($item) == 'NULL') echo '<H1>WOW! A NULL!</H1>';
echo gettype($item).'<br>';
}


function gettest(){
$lcFilter = "1|2|3";
$laFilter = explode('|',$lcFilter);

if(!empty(laFilter(0))) laReturn('jobid') = laFilter(0);
if(!empty(laFilter(1))) laReturn('stateid') = laFilter(1);
if(!empty(laFilter(2))) laReturn('storeid') = laFilter(2);

return $laReturn;
}
?>

 

When I run this, the line:

 

	if(!empty(laFilter(0))) laReturn('jobid') = laFilter(0);

 

generates the error:

 

Fatal error: Can't use function return value in write context in C:\xampp\htdocs\test.php on line 16

 

I cannot think of what is wrong with the code. It seems simple enough. Any assistance would be greatly appreciated.

 

Thanks

I figured it out. In this case, the array needed to use square brackets. It's funny, I had another case where I had to change it to regular parens... Not sure why but it seems to work now in my little test program.

 

Thanks anyway!
