匹配单独的数组值和打印结果

Question

// Setup Query
$query = $this->db->query('SELECT * FROM here');

// Pull in the appropriate data for the model
$toolkitName = $this->toolkits_model->find_by('id', $id);

// Strip the commas from incoming array
$matchMeCommas = $toolkitName->toolkits_listitems; 
$matchMe = explode(',', $matchMeCommas);    

// Print ID for each item in toolkit parent list
foreach ($query->result_array() as $row) :
echo $row['id'];
endforeach;

// Match each item from toolkit list item
foreach ($matchMe as $row2) :
echo $row2;
endforeach;

What I'm trying to do is match the values from these two arrays and print the results from the parent list item. Currently what happens is that I get two strings of "234567891011" which relates to the ID (2, 3, 4, 5, ect).

I should add that I would want to match like values and pull results for that specific ID. So if the values 2 & 4 match I would want to retrieve their information from the DB and print it.

Any ideas? Thanks!

Still not exactly sure what you want, but this could get you started:

foreach($query->result_array() as $row){
    if(in_array($row['id'], $matchMe)){
        //this is a match ... do something
    }
}

OR

You could build an array of all matches:

//get the ids from the query
$ids = array();
foreach($query->result_array() as $row){
    $ids[] = $row['id'];
}

$matches = array_intersect($matchMe, $ids);
