PHP => JSON utility is too strict

[JStruk]

The PHP to JSON utility needs to be updated to be more lenient on the php array provided.

• Allow strings with single quotes ['foo' => 'bar'] to { "foo": "bar" }
• Allow semicolons (can be removed before converting) ['foo' => 'bar']; to { "foo": "bar" }
• Interpret each value as a string? i.e We should be able to convert ['foo' => $this->bar] to { foo: '$this->bar' }
