如何将PHP数组转换成这样的格式

Array
(
    [0] => 001-1234567
    [1] => 1234567
    [2] => 12345678
    [3] => 12345678
    [4] => 12345678
    [5] => AP1W3242
    [6] => AP7X1234
    [7] => AS1234
    [8] => MH9Z2324
    [9] => MX1234
    [10] => TN1A3242
    [11] => ZZ1234
)

到下面格式的Javascript数组?

var cities = [
    "Aberdeen",
    "Ada",
    "Adamsville",
    "Addyston",
    "Adelphi",
    "Adena",
    "Adrian",
    "Akron",
    "Albany"
];

当前回答

可以用更安全的方式来做。

如果你的PHP数组包含特殊字符,你需要在PHP中使用rawurlencode(),然后在JS中使用decodeURIComponent()来转义这些字符。并将JSON解析为原生js。试试这个:

var data = JSON.parse(
        decodeURIComponent(
            "<?=rawurlencode(json_encode($data));?>"
        )
    );

console.log(data);

其他回答

您不必调用parseJSON,因为json_encode的输出是javascript文字。只要把它赋给一个js变量。

<script type="text/javascript">
    //Assign php generated json to JavaScript variable
    var tempArray = <?php echo json_encode($php_array); ?>;

   //You will be able to access the properties as 
    alert(tempArray[0].Key);
</script>

保持简单:

var jsObject = JSON.parse('<?= addslashes(json_encode($phpArray)) ?>');

我也遇到了同样的问题,我就是这样做的。

/*PHP FILE*/

<?php

$data = file_get_contents('http://yourrssdomain.com/rss');
$data = simplexml_load_string($data);

$articles = array();

foreach($data->channel->item as $item){

    $articles[] = array(

        'title' => (string)$item->title,
        'description' => (string)$item ->description,
        'link' => (string)$item ->link, 
        'guid' => (string)$item ->guid,
        'pubdate' => (string)$item ->pubDate,
        'category' => (string)$item ->category,

    );  
}

// IF YOU PRINT_R THE ARTICLES ARRAY YOU WILL GET THE SAME KIND OF ARRAY THAT YOU ARE GETTING SO I CREATE AN OUTPUT STING AND WITH A FOR LOOP I ADD SOME CHARACTERS TO SPLIT LATER WITH JAVASCRIPT

$output="";

for($i = 0; $i < sizeof($articles); $i++){

    //# Items
    //| Attributes 

    if($i != 0) $output.="#"; /// IF NOT THE FIRST

// IF NOT THE FIRST ITEM ADD '#' TO SEPARATE EACH ITEM AND THEN '|' TO SEPARATE EACH ATTRIBUTE OF THE ITEM 

    $output.=$articles[$i]['title']."|";
    $output.=$articles[$i]['description']."|";
    $output.=$articles[$i]['link']."|";
    $output.=$articles[$i]['guid']."|";
    $output.=$articles[$i]['pubdate']."|";
    $output.=$articles[$i]['category'];
}

echo $output;

?>
/* php file */


/*AJAX COMUNICATION*/

$(document).ready(function(e) {

/*AJAX COMUNICATION*/

var prodlist= [];
var attrlist= [];

  $.ajax({  
      type: "get",  
      url: "php/fromupnorthrss.php",  
      data: {feeding: "feedstest"},
      }).done(function(data) {

        prodlist= data.split('#');

        for(var i = 0; i < prodlist.length; i++){

            attrlist= prodlist[i].split('|');

            alert(attrlist[0]); /// NOW I CAN REACH EACH ELEMENT HOW I WANT TO. 
        }
   });
});

我希望这能有所帮助。

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('&quot;', '', json_encode($your_array)) }} 

为关联和非关联数组工作。

如果您需要将多维PHP数组直接打印到html页面源代码中,并以一种缩进的人类可读的Javascript对象符号(又名JSON)方式,请使用我在http://php.net/manual/en/function.json-encode.php#102091中找到的这个由绰号为“bohwaz”的人编写的漂亮函数。

<?php

function json_readable_encode($in, $indent = 0, $from_array = false)
{
    $_myself = __FUNCTION__;
    $_escape = function ($str)
    {
        return preg_replace("!([\b\t\n\r\f\"\\'])!", "\\\\\\1", $str);
    };

    $out = '';

    foreach ($in as $key=>$value)
    {
        $out .= str_repeat("\t", $indent + 1);
        $out .= "\"".$_escape((string)$key)."\": ";

        if (is_object($value) || is_array($value))
        {
            $out .= "\n";
            $out .= $_myself($value, $indent + 1);
        }
        elseif (is_bool($value))
        {
            $out .= $value ? 'true' : 'false';
        }
        elseif (is_null($value))
        {
            $out .= 'null';
        }
        elseif (is_string($value))
        {
            $out .= "\"" . $_escape($value) ."\"";
        }
        else
        {
            $out .= $value;
        }

        $out .= ",\n";
    }

    if (!empty($out))
    {
        $out = substr($out, 0, -2);
    }

    $out = str_repeat("\t", $indent) . "{\n" . $out;
    $out .= "\n" . str_repeat("\t", $indent) . "}";

    return $out;
}

?>
