function phpconsole($label='var', $x) {
    ?>
    <script type="text/javascript">
        console.log('<?php echo ($label)?>');
        console.log('<?php echo json_encode($x)?>');
    </script>
    <?php
}

干净、快速、简单，没有无用的代码:

function consolelog($data) {
    echo "<script>console.log('".$data."');</script>";
}

简短简单，适用于数组、字符串或对象。

function console_log( $data ) {
  $output  = "<script>console.log( 'PHP debugger: ";
  $output .= json_encode(print_r($data, true));
  $output .= "' );</script>";
  echo $output;
}

这两个都有效:

<?php
    $five = 5;
    $six = 6;
?>
<script>
    console.log(<?php echo $five + $six ?>);
</script>


<?php
    $five = 5;
    $six = 6;
    echo("<script>console.log($five + $six);</script>");
?>

我认为它可以被用来

function jsLogs($data, $isExit) {
    $html = "";
    $coll;

    if (is_array($data) || is_object($data)) {
        $coll = json_encode($data);
    } else {
        $coll = $data;
    }

    $html = "<script id='jsLogs'>console.log('PHP: ${coll}');</script>";

    echo($html);

    if ($isExit) exit();
}

# For String
jsLogs("Testing string"); #PHP: Testing string

# For Array
jsLogs(array("test1", "test2")); # PHP: ["test1","test2"]

# For Object
jsLogs(array("test1"=>array("subtest1", "subtest2"))); #PHP: {"test1":["subtest1","subtest2"]}

我发现这很有帮助:

function console($data, $priority, $debug)
{
    if ($priority <= $debug)
    {
        $output = '<script>console.log("' . str_repeat(" ", $priority-1) . (is_array($data) ? implode(",", $data) : $data) . '");</script>';

        echo $output;
    }
}

像这样使用它:

<?php
    $debug = 5; // All lower and equal priority logs will be displayed
    console('Important', 1 , $debug);
    console('Less Important', 2 , $debug);
    console('Even Less Important', 5 , $debug);
    console('Again Important', 1 , $debug);
?>

在控制台输出:

重要的 不那么重要 更不重要 同样重要的

您可以通过使用$debug值限制不太重要的日志来关闭它们。
