从print_r输出中删除换行符

Question

我有以下PHP代码：

$array = array('huey' => 'red', 'dewey' => 'blue', 'louie' => 'green', 'webby' => 'pink');
$postDataForLog = print_r($array, true);
$postDataForLog = str_replace('\n', ' | ', $postDataForLog);
log($postDataForLog);

我想要实现的很简单。将数组的内容写入日志文件。为了保持文件的组织，我需要将每条日志消息保持在一行上。因此，我希望将print_r的输出减少到一行，并用|替换换行符。然而，由于某些原因，这并不起作用，虽然我希望文件中的输出是这样的：

Array | ( | [huey] => red | [dewey] => blue | [louie] => green | [webby] => pink | )

它是这样的：

Array
(
    [huey] => red
    [dewey] => blue
    [louie] => green
    [webby] => pink
)

Answer 1

<?

$array = array('huey' => 'red', 'dewey' => 'blue', 'louie' => 'green', 'webby' => 'pink');

$postDataForLog = implode(" | ", $array);

echo $postDataForLog;

?>

Answer 2

$array = array('huey' => 'red', 'dewey' => 'blue', 'louie' => 'green', 'webby' => 'pink');
$postDataForLog = [];
foreach ($array as $key => $value) {
    $postDataForLog[] = "[$key] => $value";
}
echo ('Array | ( | '.implode(' | ', $postDataForLog).' | )');
//Output: Array | ( | [huey] => red | [dewey] => blue | [louie] => green | [webby] => pink | )
