Question

I have a string of delimiter-separated values, and need to perform some_func on each of the values in the string. What is the most compact/elegant way to accomplish this? Here is the code I would currently use:

$delim = ',';
$source_array = explode($delim, $source_string);

$destination_array = array();
foreach ($source_array as $val) {
    $destination_array[] = some_function($val);
}
$destination_string = implode($delim, $destination_array);

Ordering is not important, but would be nice to preserve.

Thanks!

You’re looking for array_map:

$delim = ',';
$source_array = explode($delim, $source_string);
$destination_array = array_map('some_function', source_array)
$destination_string = implode($delim, $destination_array);
