Question

I want to be able to check if a certain key exists within my array. I have an array and I’m merging multiple arrays from mysql. What would be the best way to do so?

for example

Array
(
[0] => Array
(
 [id] => 3
 [comments] => comment text
)
[1] => Array
(
 [id] => 3
 [comments] => comment text
)
[2] => Array
(
 [idMenu] => 1
 [names] => text
)
[3] => Array
(
 [idMenu] => 3
 [names] => names text
)
)

So I’m trying to see if this array has comments and/or names.

do i have to do an if statement?

Thanks

Answer 1

Assuming that your parent array will always return bunch of children arrays…

foreach ($parentArray as $childArray) {
    if (array_key_exists("comments", $childArray) { return true; }
    if (array_key_exists("names", $childArray) { return true; }
}

Now, that merely checks to see if the parent has a child array with one of those keys.. Actually checking the value to see if it is empty would take a little more code, but this should get you going in the right direction.
