Make sure values you want to be non string (like int or boolean) are entered as such into your source array:

<pre><code>&lt;?php
$a = array('id' =&gt; 1, 'really' =&gt; true, 'somevalue' =&gt; 'text');
var_dump( json_decode( json_encode( $a ) ) );
</code></pre>

gives expected:

<pre><code>object(stdClass)#1 (2) {
 ["id"]=&gt;
 int(1)
 ["really"]=&gt;
 bool(true)
 ["somevalue"]=&gt;
 string(4) "text"
}
</code></pre>

EDIT

If you want it always to be strings, then put strings in your array in first place:

<pre><code>&lt;?php
$a = array('id' =&gt; '1', 'really' =&gt; 'true', 'somevalue' =&gt; 'text');
var_dump( json_decode( json_encode( $a ) ) );
</code></pre>

would give

<pre><code>object(stdClass)#1 (3) {
 ["id"]=&gt;
 string(1) "1"
 ["really"]=&gt;
 string(4) "true"
 ["somevalue"]=&gt;
 string(4) "text"
}
</code></pre>

but that kills the whole purpose of having different variable types.

Of you can convert your array prior json encoding:

<pre><code>&lt;?php
$a = array('id' =&gt; 1, 'really' =&gt; true, 'somevalue' =&gt; 'text');

$tmp = array();
foreach( $a as $key=&gt;$val ) {
 $tmp[$key] = (string)$val;
}

var_dump( json_decode( json_encode( $tmp ) ) );
</code></pre>

would give in the end:

<pre><code>object(stdClass)#1 (3) {
 ["id"]=&gt;
 string(1) "1"
 ["really"]=&gt;
 string(1) "1"
 ["somevalue"]=&gt;
 string(4) "text"
}
</code></pre>

$json2 = array("id" =&gt; 1, "somevalue" =&gt; (string) $somevalue2);

On PHP> 5.3.3., you can use json_decode($array, JSON_NUMERIC_CHECK);

If you do not have PHP 5.3.3 or more I wrote this recursive function:

<pre><code>function json_encode_with_numbers($array) {
 if(is_array($array)) {
 if(count($array)&gt;0 &amp;&amp; array_keys($array) !== range(0, count($array) - 1)) {
 echo '{'; 

 $isFirst = true;
 foreach($array as $key=&gt;$item) {
 if(!$isFirst) {
 echo ",";
 }
 echo '"'.$key.'":';
 json_encode_with_numbers($item);
 $isFirst = false;
 }
 echo '}';
 } else {
 echo '['; 
 $isFirst = true;
 foreach($array as $item) {
 if(!$isFirst) {
 echo ",";
 }
 json_encode_with_numbers($item);
 $isFirst = false;
 }
 echo ']';
 }
 } else {
 if(is_numeric($array)) {
 echo $array;
 } elseif ($array == null) {
 echo "null";
 } else {
 echo '"'.str_replace(array('"', '\\'), array('\"', '\\\\'), $array).'"'; // escape special chars
 }

 }

}
</code></pre>

Let's say I have such JSON:

<pre><code>{
 id: 1,
 somevalue: "text"
}
</code></pre>

and I want to create this JSON by PHP function <a href="http://php.net/manual/en/function.json-encode.php" rel="nofollow">json_encode</a>. I can pretty easy get this JSON in form:

<pre><code>{
 "id": "1",
 "somevalue": "text"
}
</code></pre>

or, using <code>JSON_NUMERIC_CHECK</code>, in form where "id" will be numeric, but "somevalue" can be either numeric or text, depend on its content.

How can I make JSON where "somevalue" always be in text format (with quotes). I'll parse it by other language, where it is important.

假设我有这样的JSON：{ id: 1, somevalue: "text"}我想通过PHP函数来创建这个JSON。我可以很容易地将这个JSON转换为：{ "id": "1", "somevalue": "text"}或者，使用JSON_NUMERIC_CHECK格式，其中"id“将是数字，但"somevalue”可以...
