如何让PHP脚本从javascript中获取信息并将其写入mysql

Question

Hello I'm trying to make PHP script that pulls coordinates from this JavaScript (or from here http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/2.5_week.geojsonp) and write them to mysql. How to do that please make me tutorial?

<script>
      var map;
      function initMap() {
        map = new google.maps.Map(document.getElementById('map'), {
          zoom: 2,
          center: new google.maps.LatLng(2.8,-187.3),
          mapTypeId: 'terrain'
        });

        // Create a <script> tag and set the USGS URL as the source.
        var script = document.createElement('script');
        // This example uses a local copy of the GeoJSON stored at

        script.src = 'https://developers.google.com/maps/documentation/javascript/examples/json/earthquake_GeoJSONP.js';
        document.getElementsByTagName('head')[0].appendChild(script);
      }

      // Loop through the results array and place a marker for each
      // set of coordinates.
      window.eqfeed_callback = function(results) {
        for (var i = 0; i < results.features.length; i++) {
          var coords = results.features[i].geometry.coordinates;
          var latLng = new google.maps.LatLng(coords[1],coords[0]);
          var marker = new google.maps.Marker({
            position: latLng,
            map: map
          });
        }
      }
    </script>
    <script async defer
    src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
