/**
|
||
|
|
* 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 Zend\Json\Json can contain native
|
||
|
|
* JavaScript expressions.
|
||
|
|
*
|
||
|
|
* Example:
|
||
|
|
*
|
||
|
|
* <code>
|
||
|
|
* $foo = array(
|
||
|
|
* 'integer' => 9,
|
||
|
|
* 'string' => 'test string',
|
||
|
|
* 'function' => Zend\Json\Expr(
|
||
|
|
* 'function () { window.alert("javascript function encoded by Zend\Json\Json") }'
|
||
|
|
* ),
|
||
|
|
* );
|
||
|
|
*
|
||
|
|
* echo Zend\Json\Json::encode($foo, false, ['enableJsonExprFinder' => true]);
|
||
|
|
* </code>
|
||
|
|
*
|
||
|
|
* The above returns the following JSON (formatted for readability):
|
||
|
|
*
|
||
|
|
* <code>
|
||
|
|
* {
|
||
|
|
* "integer": 9,
|
||
|
|
* "string": "test string",
|
||
|
|
* "function": function () {window.alert("javascript function encoded by Zend\Json\Json")}
|
||
|
|
* }
|
||
|
|
* </code>
