<p>Another way would be to encode the quotes using <a href="http://php.net/manual/en/function.htmlspecialchars.php" rel="noreferrer">htmlspecialchars</a>:</p>

blocks|key|562251|text|我成功地做到了这一点：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|562252|$json+=+str_replace("\u0022","\\\\\"",json_encode(+$phpArray,JSON_HEX_QUOT));+|code-block|syntax|javascript|562253|默认情况下，json_encode()会将"转义为\"。但对于json.PARSE()来说，它仍然是错误的JSON。因此，通过添加选项JSON_HEX_QUOT，json_encode()将用\u0022替换"。json.PARSE()仍然不会喜欢\u0022。因此，我们需要用\\"替换\u0022。\\\\\"是转义的\\"。|offset|length|style|CODE|562254|注意:如果您有HEX单引号问题，您可以添加选项JSON_HEX_APOS，将单引号替换为unicode+javascript值。|562255|例如：json_encode(+$phpArray,+JSON_HEX_APOS%7CJSON_HEX_QUOT+));|562256|entityMap^0|0|0|6|D|L|1|P|2|V|C|1V|D|29|D|2O|6|2W|1|2Y|C|3G|6|3V|3|40|6|47|6|4H|3|0|7|3|N|D|0|3|1J|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@$I|V|J|W|K|L]|$I|X|J|Y|K|L]|$I|Z|J|10|K|L]|$I|11|J|12|K|L]|$I|13|J|14|K|L]|$I|15|J|16|K|L]|$I|17|J|18|K|L]|$I|19|J|1A|K|L]|$I|1B|J|1C|K|L]|$I|1D|J|1E|K|L]|$I|1F|J|1G|K|L]|$I|1H|J|1I|K|L]|$I|1J|J|1K|K|L]|$I|1L|J|1M|K|L]]|9|@]|A|$]]|$1|M|3|N|5|6|7|1N|8|@$I|1O|J|1P|K|L]|$I|1Q|J|1R|K|L]]|9|@]|A|$]]|$1|O|3|P|5|6|7|1S|8|@$I|1T|J|1U|K|L]]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|1V|8|@]|9|@]|A|$]]]|R|$]]

<p>I succefully just did this : </p>

<pre><code>$json = str_replace("\u0022","\\\\\"",json_encode( $phpArray,JSON_HEX_QUOT)); 
</code></pre>

<p><code>json_encode()</code> by default will escape <code>"</code> to <code>\"</code> . But it's still wrong JSON for <code>json.PARSE()</code>.  So by adding option <code>JSON_HEX_QUOT</code>, <code>json_encode()</code> will replace <code>"</code> with <code>\u0022</code>.  <code>json.PARSE()</code> still will not like <code>\u0022</code>.  So  then we need to replace <code>\u0022</code> with <code>\\"</code>.  The <code>\\\\\"</code> is escaped <code>\\"</code>.</p>

<p>NOTE : you can add option <code>JSON_HEX_APOS</code> to replace single quote with unicode <code>HEX</code> value if you have javascript single quote issue.</p>

<p>ex: <code>json_encode( $phpArray, JSON_HEX_APOS|JSON_HEX_QUOT ));</code> </p>

<p>I'm creating a JSON string from a PHP array. I've encoded it using <code>json_encode()</code>.</p>

<pre><code>$data = array(
    'title' =&gt; 'Example string\'s with "special" characters'
);

$data = json_encode( $data );
</code></pre>

<p><code>$data</code> is localized using <code>wp_localize_script()</code> and is accessible via a global <code>data</code> variable.</p>

<p>In the JS file I can access the information by the following:</p>

<pre><code>var data     = data.replace( /&amp;quot;/g, '"' ),
    jsonData = jQuery.parseJSON( data );

console.log( jsonData );
</code></pre>

<p>This results in an output of:</p>

<pre><code>{ "title":"Example string's with "special" characters" }
</code></pre>

<p>Entering that result into <a href="http://jsonlint.com/" rel="noreferrer">http://jsonlint.com/</a> returns an error. Removing the double quotes around "special" validates the string.</p>

<p>What is the best way to create a JSON string from PHP and properly escape it for use in a JS file?</p>


PHP JSON String, escape Double Quotes for JS output

jQuery

JSON

我正在从PHP数组创建一个JSON字符串。我已经用json_encode()对它进行了编码。$data = array(    'title' => 'Example string\'s with "special" characters');$data = json_encode( $data );$data使用wp_localize_script()进行本地化，并可通过全局data变量进行访问
