File_put_contents

     

Here is how I would use it in an Ajax điện thoại tư vấn, if I don"t find a pure client way khổng lồ vì this.

$homepage = file_get_contents("http://www.example.com/");emang đến $homepage;Is there way lớn bởi this client side instead so I don"t have sầu to lớn ajax the string over?

you could vì

JS code:

$.post("phppage.php", url: url , function(data) document.getElementById("somediv").innerHTML = data; );PHPhường code:

$url = $_POST<"url">;eđến file_get_contents($url);That would get you the contents of the url.

JavaScript cannot go out and scrape data off of pages. It can make a Điện thoại tư vấn khổng lồ a local PHP script that then goes on its behalf và grabs the data, but JavaScript (in the browser) cannot vì chưng this.

$.post("/localScript.php", srcToGet: "http://example.com" , function(data) /* From within here, data is whatever your local script sent bachồng to lớn us */);You have options lượt thích JSONPhường & Cross-Origin Resource Sharing at your disposal, but both of those require web1_setting up the other kết thúc, so you cannot just choose a domain name & start firing off requests for data.

This function will return the tệp tin as a string just like the PHPhường file_get_contents().

function file_get_contents(uri, callback) fetch(uri).then(res => res.text()).then(text => callback(text));However unlike PHP.., JavaScript will go on lớn the next statement, not waiting for the data lớn return.

It"s 20đôi mươi và some modern approach;

async function file_get_contents(uri, callback) let res = await fetch(uri), ret = await res.text(); return callbaông xã ? callback(ret) : ret; // a Promise() actually.file_get_contents("https://httpbin.org/get", console.log);// orfile_get_contents("https://httpbin.org/get").then(ret => console.log(ret));
Not in a general sense. Cross-domain restrictions disallow Javascript code from doing this.

If the target site has CORS (cross-origin resource sharing) set up, you can use XMLHttpRequest to lớn load files. Most sites vày not, as it"s off by mặc định for security reasons, và is rarely necessary.

If you just need to lớn include an HTML page, you can stichồng it in an element. This is subject to some layout gotchas, though (the page ends up in a fixed-form size element).


Or You can use php.js library. Which allow some php functions for javascript. file_get_contents() function one of them.
