如何将PHP数组转换为JSON数组？ [关闭]
问题描述：
For example, I have the following code in JSON:
{
"tag": "img",
"attr": [
{
"alt": "text",
"src": "url",
"void": "true",
"all": "true"
}
]
}
What PHP code should I use to echo/print the code above?
I tried this:
$arr = array (
"tag" => "img",
$attr = array (
"alt" => "text",
"src" => "url",
"void" => "true",
"all" => "true"
)
);
And then:
echo $arr = json_encode($arr);
But I get error. Any ideas?

Your array declaration is wrong. It should be:
$arr = array (
"tag" => "img",
"attr" => array (
"alt" => "text",
"src" => "url",
"void" => "true",
"all" => "true"
)
);

Change to -
$arr = array (
"tag" => "img",
"attr" => array (
"alt" => "text",
"src" => "url",
"void" => "true",
"all" => "true"
)
);
ie. $attr = array ( to "attr" => array (
