PHP values into javascript

                <script type="text/javascript">
                    var places = [];
                </script>
                <?php
                $date = $_POST['orderdate'];
                $file = fopen("http://www.spc.noaa.gov/climo/reports/".$date."_rpts_hail.csv", "r");
                $content = fgetcsv($file, 1000, ",");
                $id = 1;
                while (($content = fgetcsv($file, 1000, ",")) !== FALSE) {

                    <?php           
                    }

Is there any way that when a page loads, some php code will run and get an array of information and then have that information be put into a javascript variable to use?

Yes.

Use for example json_encode():

<?php 
   $array = array("first" => 1, "second" => 2, "third" => 3, "fourth" => 4);
 ?>

 <script>
   var my_array = <?php echo json_encode($array); ?>
   alert(my_array[1]); // alerts "first"
 </script>
