Use string to store statement (or part of a statement), and then add it to the code
- by Dean
I use multidimensional arrays to store product attributes (well Virtuemart does, to be precise).
When I tried to echo the sub-arrays value, if the sub-array did not exist PHP threw:
Fatal error: Cannot use string offset
as an array
To get around this, I attempted to create a function to check on every array level if it is an actual array, and if it is empty (when trying on the whole thing at once such as: is_array($array['level1']['level2']['level3']), I got the same error if level1 or level2 are not actual arrays).
This is the function ($array contains the array to check, $array_levels is an array containing the names of the sub-arrays, in the order they should apper):
function check_md_array($array,$array_levels){
if(is_array($array)){
$dimension = null; //This will store the dimensions string
foreach($array_levels as $level){
$dimension .= "['" . $level . "']"; //Add the current dimension to the dimensions string
if(!is_array($array/* THE CONTENT OF $dimension SHOULD BE INSERTED HERE*/)){
return false;
}
}
return true;
}
}
How can I take the string contained in $dimensions, and insert it into the code, to be part of the statement?
