Call the node js script from PHP and retrieve all data back to PHP

[can...@gmail.com]

Hello 

I managed to write a nodejs script that is scrapping info. 
I can print the info while I run the node script.

Now I would like to call that nodescript from PHP and output all its data back to PHP.

How can I do that ?

Thanks

It does not sound like a question related specifically to Headless Chrome (interfacing between Node.js and PHP), so this is probably not the right group for it. Maybe stackoverflow.com (though you will need to show some code that you tried and did not work, regardless of where you ask this).

Hello

Yes it is chrome headless related here is my code

'use strict';

const puppeteer = require('puppeteer');

(async() => {

const browser = await puppeteer.launch({headless: true});
const page = await browser.newPage();
await page.setRequestInterception(true);
page.on('request', request => {
if (request.resourceType() === 'image')
request.abort();
else
request.continue();
});
await page.goto('http://example.com');

const TITLE_PAGE = '.main-title h1';

let innerTitle = await page.evaluate((sel) => {
let html = document.querySelector(sel).innerHTML;
console.log(html);
return html.toString();
}, TITLE_PAGE);
console.log(innerTitle);

await page.waitForSelector(".date-list");

const REAL_TIME = '.date-list';

let innerTimes = await page.evaluate((sel) => {
let arTimes = document.querySelectorAll(sel);
let sTimes = "";
for(var i=0; i<arTimes.length;i++)
{
sTimes += arTimes[i].innerHTML+"|";
}
return sTimes;
}, REAL_TIME);
console.log(innerTimes);
console.log("load page");
/*so far I am printing in CLI*/
/*looking to export these data to php*/

await browser.close();
})();

Hello,

When I am using 

process.stdout.write("init");

outside of (async() => {

everything is working I can print and PHP has the data back.

but when I am printing the data inside (async() => {  then it returns 0;

I understand that it is async but still, is there a way to make it work ?

Any suggestions ? 
Thanks

I'm sorry but this isn't really the right forum for php / nodejs interoperability questions.  None of us here use php and few of us use nodejs so we don't know how to help.

Hello Alex,
I understand completely. I thought that some people on this forum were using chrome headless for web scrapping thus my question regarding how to collect back the data.

Thank you
