在php变量中检索javascript变量[重复]

• How do I pass variables and data from PHP to JavaScript? 19 answers

I am trying to dynamically create variables in javascript. In my PHP code I already dynamically create variables from SQL output which gives me $res1, $res2, etc. Now I want to use these in my javascript but of course I cannot hardcode it for I can never know how many of the $res variables the PHP will generate.
I have the feeling I am already fairly close though. I have the following:

var i=1;
while (i<=count) {
    var name = "<?php ${"res".$_GET['i']} ?>";
}

</div>

The php will be ran once after the server request, so $_GET[i] will only have one value for the entire loop. Which I'm presuming is not your desired effect.

Try handling the variables on the backend and pushing them all into a array then sending that to the browser.

for (var i = 0; i < data.length; i++) {
    var name = data[i];
}

where data is an array sent back from the server.
