Question

Here’s what the first array outputs:

Array ( 
[0] => Array ( [id] => 67 [title] => avatar delete any ) 
[1] => Array ( [id] => 66 [title] => avatar edit any ) 
[2] => Array ( [id] => 65 [title] => avatar upload ) 
[3] => Array ( [id] => 8 [title] => comments edit own ) 
[4] => Array ( [id] => 6 [title] => comments post ) 
[5] => Array ( [id] => 9 [title] => comments remove own ) 
[6] => Array ( [id] => 7 [title] => comments vote ) 
[7] => Array ( [id] => 5 [title] => get other members emails )
[8] => Array ( [id] => 1 [title] => send greetings ) 
[9] => Array ( [id] => 4 [title] => send messages ) 
[10] => Array ( [id] => 64 [title] => use flip chat ) 
[11] => Array ( [id] => 11 [title] => videos add ) 
[12] => Array ( [id] => 13 [title] => videos approve ) 
[13] => Array ( [id] => 12 [title] => videos delete ) 
[14] => Array ( [id] => 14 [title] => videos edit ) 
[15] => Array ( [id] => 10 [title] => videos view ) 
[16] => Array ( [id] => 2 [title] => view profiles ) 
[17] => Array ( [id] => 3 [title] => vote ) )

The Second array outputs this:

Array (
[2] => Array ( [id] => 2 [title] => view profiles [AllowedCount] => 5 [AllowedPeriodLen] => 5 ) 
[3] => Array ( [id] => 3 [title] => vote [AllowedCount] => 0 [AllowedPeriodLen] => 0 ) )

I’m using a foreach to loop through the first array to display actions that are enabled. How would I check if the Key of the second array matches the key of the First, then give variables values from AllowedCount, and AllowedPeriodLen?

Answer 1

i’d reconsider my array design
if the id is really a unique number then redesign the first array to be like that:

$arr1 = Array ( 
[67] => avatar delete any
[66] => avatar edit any  
... 
)

the second one like that

$arr2 = Array (
[2] => Array ( [title] => view profiles [AllowedCount] => 5 [AllowedPeriodLen] => 5 ) 
[3] => Array ( [title] => vote [AllowedCount] => 0 [AllowedPeriodLen] => 0 ) )

so that the line matches the id’s

then just do something like

foreach($arr2 as $key=>$element){
    echo $arr1[$key];
}
