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"
];

这里有许多好的和复杂的解决方案，这是一种不需要在用户端解析json的方法。
$mtc=array();
$replace=array();
$x = json_encode($thearray);
preg_match_all('/"[a-z0-9_]*":/',$x,$mtc);
foreach($mtc[0] as $v){
array_push($replace,str_replace('"','',$v));
}
$x = str_replace($mtc[0],$replace,$x);
echo '<script type="text/javascript">x='.$x.';console.log(x);</script>';
这适用于具有多个级别的索引数组和关联数组(任何组合)，并且不需要用户端json解析。

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。
你也可以这样做
<script>
<?php
$php_array = array('abc','def','ghi');
?>
var array_code = <?php echo json_encode($php_array); ?>;
console.log(array_code);
</script>
对于Laravel, Blade{{}}语句通过PHP的htmlspecialchars函数自动发送，以防止XSS攻击。你的数据是不转义的，你可以使用以下语法:
const jsArray = {!! str_replace('"', '', json_encode($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);
