字符串的键和索引 - 扭曲内爆

Question

Snippet:

$temp = array();
foreach ($data as $key => $value) {
    // This line varies, from HTML to URLs, to anything in between
    array_push($temp, "<b>$key:</b> $value"); 
}
$request = implode('<br/>', $temp); // Glue also varies depending on needs
unset($temp);

This is a getaway from the usual $string .= 'blah<br/>'. Never mind the rtrim.

Can anyone show me a better way to achieve above without use of a temp array and possibly without a loop? Bonus points for not using above code in a function, lambda acceptable though.

P.S. While writing this question I have found a wonderful http_build_query(). One down, one to go.

Edit:

What result should look like:

<b>Title: </b> Value</br>
<b>Title2: </b> Value2</br>
<b>Title3: </b> Value3

Or with different settings (not required, but shows possibility):

key=value&key2=value2&key3=value3

I am trying to improve my code, I use the above snippet everywhere.

Answer 1

My answer: There are some ways, but:

Loops & arrays are the best friends of any programmer.

They provide pretty good readability, reusability and generally are considered to be a right way for performing pretty much the same actions.

You may also take a look on array_map or array_walk. Less code, but it is a loop anyways.

array_walk($data, function($value, $key){
  $temp[] = "<b>{$key}:</b> {$value}" ;  //Shorthand for array_push is $arr[] = $value ;
}) ;
