Class Expr

Encode a string to a native JavaScript expression.

This class simply holds a string with a native JavaScript expression, so objects or arrays to be encoded with Laminas\Json\Json can contain native JavaScript expressions.

Example:

$foo = array(

'integer'  => 9,
'string'   => 'test string',
'function' => Laminas\Json\Expr(
    'function () { window.alert("javascript function encoded by Laminas\Json\Json") }'
),

echo Laminas\Json\Json::encode($foo, false, ['enableJsonExprFinder' => true]);

The above returns the following JSON (formatted for readability):

{ "integer": 9, "string": "test string", "function": function () {window.alert("javascript function encoded by Laminas\Json\Json")} }
