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"
];

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。

下面是一个将PHP数组转换为JavaScript数组的非常简单的技巧:
$array = array("one","two","three");
JS下面:
// Use PHP tags for json_encode()
var js_json = json_encode($array);
var js_json_string = JSON.stringify(js_json);
var js_json_array = JSON.parse(js_json_string);
alert(js_json_array.length);
这招很管用。
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:
这是我的函数。JavaScript必须在PHP下，否则使用SESSION。
<?php
$phpArray=array(1,2,3,4,5,6);
?>
<div id="arrayCon" style="width:300px;"></div>
<script type="text/javascript">
var jsArray = new Array();
<?php
$numArray=count($phpArray);
for($i=0;$i<$numArray;$i++){
echo "jsArray[$i] = ". $phpArray[$i] . ";\n";
}
?>
$("#arrayCon").text(jsArray[1]);
</script>
最后一行可以是....text(jsArray);会显示"1,2,3,4,5,6"
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>
