JSON PHP Array для Javascript

Можно ли JSON использовать этот php-массив через json_encode? Поскольку этот php-массив называется $data и когда я делаю ..

 var myJson = <?php echo json_encode($data) ?>; console.log(myJson); 

в javascript это дает мне ошибки. Мне было интересно, существует ли ограничение на то, какие типы php-массивов JSON могут / не могут сделать.

Сначала вам нужен PHP-файл на сервере Apache где-нибудь с установленным PHP. Создайте файл следующим образом:

localhost:8888/myfile.php

 <?php $arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5); echo json_encode($arr); // {"a":1,"b":2,"c":3,"d":4,"e":5} ?> 

Тогда ваш JavaScript (в этом примере я использую jQuery ):

 $.getJSON('http://localhost:8888/myfile.php', function(data) { console.log(data); }); 

Это должно стать началом для создания массивов PHP для вашего JavaScript.

Поскольку @Allendar сказал, что вы не можете встроить PHP в JS-файл. Однако вы можете добавить функцию в свой JS-файл для загрузки данных JSON, а затем вставить эти данные в тег скрипта в ваш PHP-файл.

example.js:

 var loadJsonFromPHP = function(json) { console.log(json); } 

example.php:

 <?php $data = array("some", "test", "data"); ?> <html> <head> <script src="example.js"></script> <script> loadJsonFromPHP(<?php echo json_encode($data) ?>); </script> </head> <body></body> </html> 

Изменить: предполагается, что вам нужно только получить данные в JS один раз при загрузке страницы, и в этом случае вы можете пропустить выполнение запросов AJAX.

Передача PHP JSON на Javascript и чтение

var stuff = <?php print json_encode($datajson); ?>; var arr = new Array(); arr= JSON.parse(stuff); document.write( arr[0].cust_code );

JSON может обрабатывать любой тип массива (хотя он будет передавать ассоциативные массивы как объекты). Проблема, с которой вы, вероятно, сталкиваетесь, заключается в том, что вы пытаетесь выводить с PHP, когда данные доступны только на Javascript.

Чтобы уточнить: как только страница загрузится, PHP ничего не может сделать. Только javascript может обрабатывать вещи на стороне клиента, PHP работает только на сервере и не знает состояния клиента.

Я никогда не пытался делать что-то подобное, но я думаю, что у вас проблема, потому что json_encode возвращает строку, закодированную json. Затем вам нужно декодировать эту строку на стороне JavaScript. Попробуйте следующее:

 var myJson = JSON.parse(<?php echo json_encode($data) ?>); console.log(myJson);
