PHP conditions within an array

Question

Is it possible to use conditions within an array:

Uses define('COMPANY_ADDRESS_1','something here'); << if empty don't want to be in the array
$invoice->setFrom(array(COMPANY_NAME,COMPANY_ADDRESS_1,COMPANY_ADDRESS_2,COMPANY_TOWN,COMPANY_COUNTY,COMPANY_POSTCODE));

For example COMPANY_ADDRESS_2 is not set and doesn't show in the array so at the moment the output ends up like:

company name
company address 1
<<<<<<<<<< leaves a gap here
company town
company county
company postcode

The output is fine but if nothing is set for example COMPANY_ADDRESS_2 I want to remove it from the array altogether as it's passed to a PDF generator and currently writing as a blank line.

Sorry fixed question, the output is fine but if nothing is set for example COMPANY_ADDRESS_2 i want to remove from the array all together as its passed to a PDF generator and writing as a blank line. — James

I done and same issue, shows a space in the address line: $invoiceFromArray = $invoice->setFrom(array(COMPANY_NAME,COMPANY_ADDRESS_1,COMPANY_ADDRESS_2,COMPANY_TOWN,COMPANY_COUNTY,COMPANY_POSTCODE)); $invoiceFromArray = array_filter($invoiceFromArray); — James

And are you sure if the result depends only of if the element present in array or not? Why you form manually array without this one element and see what will appear? — Kancho Iliev

According to your question i think your array look like below:-

Array
(
    [0] => company name
    [1] => company address 1
    [2] => 
    [3] => company town
    [4] => company county
    [5] => company postcode
)

So you need to do in following manner:-

<?php

$result = array('company name','company address 1','','company town','company county','company postcode');//original array
$newArray = array();
foreach($result as $value){
    if($value != ''){
        $newArray[] = $value;
    }
}
echo "<pre/>";print_r($newArray);
echo "<pre/>";print_r(array_filter($result));
?>

Output:-

Array //null value or empty value removed and array is re-indexed
(
    [0] => company name
    [1] => company address 1
    [2] => company town
    [3] => company county
    [4] => company postcode
)

Array //null value or empty value removed without re-indexed
(
    [0] => company name
    [1] => company address 1
    [3] => company town
    [4] => company county
    [5] => company postcode
)
