Kind of.
PHP runs on the server and can create html, css, javascript et al.
However, PHP will complete it's task before the browser see's
anything. Once the browser see's the code, it's up to the browser to
interpret and run html, css, and javascript.
If your html is a form (i.e., submit), or you have javascript
running, then either of those can trigger a php script on the server
to run which can repeat the process in generating new html, css, and
javascript (if needed). Normally, javascript is not generated by PHP,
but it can be.
Using javascript to trigger an event certainly works IF javascript is
turned on by the user's browser. However, this is something that you
have absolutely no control over. A user can turn javascript ON/OFF at
their discretion. You see, many people turn javascript off because of
security concerns -- and those concerns are not without foundation.
