jQuery Forum

Hi I have a question. Is it possible to use php with javascript and
even jquery?
I want to make an if and then statment in php where it checks the
database if their is a photo/image present or not, if not then a table
that supposed to show the image would not be visiable if their is a
image then the table becomes visiable and will show the image.
Is this possible?? is they any examples that shows javascript working
with php??
