anyone know how to fix the array_merge problem from PHP 4 to 5

[c_shelswell]

Hi i'm using PHP 4.x on my dev box and i've just uploaded a test page to my server which recently upgraded to php 5.

I'm using array_merge and it works just great on my box but when i stuck it online i get this:
Warning: array_merge_recursive() [function.array-merge-recursive]: Argument #4 is not an array

I've tried array_merge_recursive too but to no effect.

here's my code:

$startDatesArray = array_merge_recursive($m, $c, $r, $gr, $cr);

all the $m, $c etc variables are arrays as well.

bit stuck. Did a bit of googling and found that it's a php 4 -> 5 thing i just can't find how to sort it.

cheers

The manual says nothing about a difference in 4-5. What are the variables? The error says $gr is not an array. Can you run print_r($gr); before this and see what it puts out?

Sorry i found my problem. What i needed to do was define my other arrays as arrays

i.e.
$m =array();$mE =array();

if ($mainAccounts)
{
$m = (get_start_dates($mainAccounts));
$mE = (get_end_dates($mainAccounts));
}

$startDatesArray = array_merge($m, $c, $r, $gr, $cr);

then it works fine.

Definately a php5 thing though as it works fine the other way on my box.

Just CAST them, but the error is telling you, one of the parameter is not an array

[code]$startDatesArray = array_merge ( ( array ) $m, ( array ) $c, ( array ) $r, ( array ) $gr, ( array ) $cr );[/code]

printf

That seems to indicate the arrays are never being filled. I'd suggest you check, perhaps they are not being filled due to some other reason - but if
$m = (get_start_dates($mainAccounts));

should return an array, and you have to explicitly define $m as an array, that tells me that $m is not ever being filled.

Good luck anyway.
