declaring array's

[sabret00the]

what's the quickest way to find out which arrays you forgot to declare in a script?

[Marco van Herwaarden]

Rewrite you script and this time decalre all arrays before using them

[Michael Morris]

The print_r function will print out all values of an array and it's indeces. But as Marco pointed out, it's good programming practice to declare all variables at the start of the script. I'd also recommend using unset on the variable first to clear out any injected value.

gah i know theirs an undefined array in here somewhere but i can't find it

this does mean undeclared array right?

PHP Code:

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in \global.php on line 334

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in \global.php on line 376

Warning: Invalid argument supplied for foreach() in \includes\functions.php on line 2386

Well you are passing a variable that is not an array somewhere where an array is expected, that's for sure.

Did you do a:

PHP Code:

// get special phrase groups
$phrasegroups = array();

// get special data templates from the datastore
$specialtemplates = array();

// pre-cache templates used by all actions
$globaltemplates = array();

// pre-cache templates used by specific actions
$actiontemplates = array(); 


before calling global?

yup always

oh well i'll find it it's in one of two scripts so shouldn't be that hard to find.

You used to be able to use non-arrays in array_merge, this changed not to long ago in php and now array_merge only accepts arrays.
