How does php play sound?

PHP uses H5 audio to achieve a sound prompt similar to Meituan's order, and the web page plays music effects.

We often do the function of internal message and message reminder, so how to add a cue tone on this basis? Today, I would like to share with you the whole process of function implementation.

First of all, we need to lay out the good news prompt style, here you can layout according to your own needs.

Once we have done the style of the message prompt, we need to start doing timers and asynchronously querying data.

$(function () {var set = setInterval (function () {$.post ("{: url ('prompt')}",'', function (data) {if (data.status) {$('# num') .html (data.num); / / add the number of messages to var audio = new Audio (". / song.ogg") / / to obtain local audio files, ogg,mp3 can audio.play (); / / perform playback operation}}, 'json');}, 1000) / / Click to view carefully and empty the number of messages $('# num' Linklink') .click (function () {$('# link) .html (';})})

Here we use the audio () of H5 to play the tone. My code here is very rough, so you can optimize it according to your own needs.

Next, we use PHP language to read new messages in the database, start pushing if there is, and ignore it if not. I'm based on TP5.1.

Public function prompt () {/ / whether there is a new order here. If so, ignore $num = Db::name ('hexiao')-> where (' add_time','>', date ('Y-m-d Hlav, time ()-10))-> count (); if ($num > 0) {return json ([' status' = > 1, 'num' = > $num]) } else {return json (['status' = > 0,' num' = > $num]);}}

The following describes the audio tag of H5, which currently supports MP3, Ogg and Wav.

Playback and pause and replay can also be controlled.

You can also control audio playback and pause through js.

Function repeat () {var audio = document.getElementById ('music'); audio.currentTime = 0 lead / replay} function control () {var audio = document.getElementById (' music'); if {if (audio.paused) {audio.play (); / / play} else {audio.pause () / / pause} at this point, the study on "how to play sound by php" is over.
