将JSON web服务中的UTF-16数据解析为PHP中的字符串

实际上,通过使用iconv(),有一种更简单的方法来读取此JSON。

// Query Home Front Command API
// Accessible only from Israel    
$json = @file_get_contents( 'http://www.oref.org.il/WarningMessages/alerts.json' );

// Got a response from the API?    
if ( $json ) {
    // Convert from UTF-16 to UTF-8    
    $json = @iconv( 'UTF-16', 'UTF-8', $json );

    // Succeeded?    
    if ( $json ) {
        // Trim JSON of whitespace    
        $json = trim( $json );

        // Convert JSON string to object    
        $json = @json_decode( $json );

        // Output JSON object           
        var_dump( $json );
    }
}

你的问题

参见:

die(var_dump(file_get_contents ("http://www.klh-dev.com/adom/alert/alerts.json")));

网页alerts.json未正确编码。参见输出:

string '��{� � � �"�i�d�"� �:� �"�1�4�0�5�2�5�4�5�8�0�5�6�8�"�,� �
�"�t�i�t�l�e�"� �:� �"������ ������ ������ ������ �"�,�
� �"�d�a�t�a�"� �:� �[� � �"����� ���� �2�2�8�"� � �]� � �}� � �' (length=206)

解决方案

你必须清理你的绳子。删除除阿拉伯字符以外的所有字符后的空字符“\0”, 和 字符串开头的“”(它是 UTF-16 mark ).

iconv函数请参见: Convert UTF-16LE to UTF-8 in php

UTF-16: PHP File Opening Encoding Problem?

<?php
$web = file_get_contents ("http://www.klh-dev.com/adom/alert/alerts.json");

$str_datakey = join("\0", preg_split("//", '"data" : ['));
$pos_datakey = strrpos($web, $str_datakey) + strlen($str_datakey);

preg_match('#"\0t\0i\0t\0l\0e\0"\0.+"\0(.*)"#', $web, $match);
preg_match('#"\0(.*)"#', $web, $match2, null, $pos_datakey);

// Replace title to replace null bit except title (with arabic char)
$title = $match[1];
$web = str_replace($title, "[HorsSujet]", $web);

// Replace string data to replace null bit except string data (with arabic char)
if (!empty($match2)) {
    $match2 = array_slice($match2, 1);
    $web = str_replace($match2, "[HorsSujet_data]", $web);
}

$web = str_replace(array('ÿþ', "\0"), "", $web);

$title = iconv("UTF-16LE", "UTF-8", $title);

for ($i = 0; $i < count($match2); $i++) {
    $match2[$i] = iconv("UTF-16LE", "UTF-8", $match2[$i]);
}

$web = str_replace("[HorsSujet]", $title, $web);

if (!empty($match2)) {
    $web = str_replace(array("[HorsSujet_data]"), $match2, $web);
}

$json = $web;

$array = json_decode($web);

var_dump($match, $match2, $web, $array);

参见输出:
