很简单，我用这个方法:

JAVASCRIPT:

var arrayJavascript = <?php echo json_encode($arrayPhp) ?>;

转换PHP数组到Javascript

的问候!

这么简单…!

使用这个方法:

<?php echo json_encode($your_array); ?>; 

在laravel blade{{}}中使用以下方法:

{{ str_replace('"', '', json_encode($your_array)) }} 

为关联和非关联数组工作。

对于PHP4中的多维数组，您可以使用以下添加到Udo G发布的代码:

function js_str($s) {
   return '"'.addcslashes($s, "\0..\37\"\\").'"';
}

function js_array($array, $keys_array) {
  foreach ($array as $key => $value) {
    $new_keys_array = $keys_array;
    $new_keys_array[] = $key;
    if(is_array($value)) {          
      echo 'javascript_array';
      foreach($new_keys_array as $key) {
        echo '["'.$key.'"]';
      }
      echo ' = new Array();';

      js_array($value, $new_keys_array);
    } else {
      echo 'javascript_array';
      foreach($new_keys_array as $key) {
        echo '["'.$key.'"]';
      }
      echo ' = '.js_str($value).";";                        
    }
  } 
}

echo 'var javascript_array = new Array();';
js_array($php_array, array());

愚蠢而简单:

var js_array = [<?php echo '"'.implode('","', $php_array).'"' ?>];

对于Laravel用户:使用@json

var cities = @json($data);

官方文档中有解释:https://laravel.com/docs/8.x/blade#rendering-json:

我使用了一个伪php数组

<?php 
       // instead to create your array like this
       $php_array = ["The","quick","brown","fox","jumps","over","the","lazy","dog"];

       // do it like this (a simple variable but with separator)
       $php_fake_array = "The,quick,brown,fox,jumps,over,the,lazy,dog";
?>

<script type="text/javascript">

        // use the same separator for the JS split() function
        js_array = '<?php echo $php_fake_array; ?>'.split(',');

</script>

如果你的数组是未知的(已经创建)

<?php 
        $php_array = file('my_file.txt');
        $php_fake_array = "";

        // transform your array with concatenate like this
        foreach ($php_array as $cell){

            // since this array is unknown, use clever separator
            $php_fake_array .= $cell.",,,,,"; 
        }
?>

<script type="text/javascript">

        // use the same separator for the JS split() function
        js_array = '<?php echo $php_fake_array; ?>'.split(',,,,,');

</script>
