PHP conditions within an array - php

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.

Answer 1

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
)
