Nothing will be faster than a simple loop. You can mix-and-match some array functions to do it, but they’ll just be implemented as a loop too. function whatever($array, $key, $val) { foreach ($array as $item) if (isset($item[$key]) && $item[$key] == $val) return true; return false; }
Why not just use $dataarray[$row[‘id’]] = $row[‘data’]; ?
Better: $resultstr = array(); foreach ($results as $result) { $resultstr[] = $result->name; } echo implode(“,”,$resultstr);
Can’t be done with a simple command, but you can use a loop: foreach(array_keys($output) as $key) { unset($output[$key][1]); }

For your limited use case, this’ll do it: $oneDimensionalArray = array_map(‘current’, $twoDimensionalArray); This can be more generalized for when the subarrays have many entries to this: $oneDimensionalArray = call_user_func_array(‘array_merge’, $twoDimensionalArray);
Simplest way, when you have only one item in inner arrays: $values = array_map(‘array_pop’, $array); $imploded = implode(‘,’, $values); EDIT: It’s for version before 5.5.0. If you’re above that, see better answer below 🙂
As Kris Roofe stated in his deleted answer, array_column is indeed a more elegant way. Just be sure to put it into some kind of a foreach loop, similar to what Sahil Gulati showed you. For example, like this: $result = array(); foreach($where[‘id’] as $k => $v) { $result[] = array_column($where, $k); } The var_dump … Read more

Quite simple: $input = array( array( ‘tag_name’ => ‘google’ ), array( ‘tag_name’ => ‘technology’ ) ); echo implode(‘, ‘, array_map(function ($entry) { return $entry[‘tag_name’]; }, $input)); http://3v4l.org/ltBZ0 and new in php v5.5.0, array_column: echo implode(‘, ‘, array_column($input, ‘tag_name’));
