where to import the jquery.js file
<p>I was wondering where I should write the <code>&lt;script src="jquery.js"&gt;&lt;/script&gt;</code> in a php project.
I wrote it in the main file menu.phpm in the head and I then include this file in other files but if I do that the jquery functions I use don't work in the other files while if I add again <code>&lt;script src="jquery.js"&gt;&lt;/script&gt;</code> in the other file, it work.
Do I have to write that in every file in which I use jquery functions?</p>

<p>thank you</p>
