I found this example code that shows how to sleep in NodeJs: function sleep(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } async function demo() { console.log(‘Taking a break…’); await sleep(2000); console.log(‘Two seconds later, showing sleep in a loop…’); // Sleep in loop for (let i = 0; i < 5; i++) { […]
After you have installed NodeJs, just run: node script.jsnode script.js It will run script.js file!
Do you need to install a NodeJs module/package/library? First create the project directory: mkdir TestProject cd TestProjectmkdir TestProject cd TestProject Make the directory the root of your project: npm init –yesnpm init –yes Install the required NodeJs modules/packages (i.e “request”): npm install request –savenpm install request –save * With -save parameter, the installed modules will […]
Here is an example of using NodeJs “request” library with error handling: var dateformat = require(‘dateformat’); var request = require(‘request’); request.get(‘https://www.google.com/’,function(err, res, body) { if(err) console.error(‘[Request.Get] %s Error:’, dateformat(new Date(), "yyyy-mm-dd h:MM:ss"), err.message); console.log(‘[Request.Get] %s StatusCode:’, dateformat(new Date(), "yyyy-mm-dd h:MM:ss"), res.statusCode); });var dateformat = require(‘dateformat’); var request = require(‘request’); request.get(‘https://www.google.com/’,function(err, res, body) { if(err) […]
Here is an example of using NodeJs “https” library with error handling: var dateformat = require(‘dateformat’); var https = require(‘https’); try { var httpsget = https.get(‘https://www.google.com/’, function(res) { console.log(‘[HTTPS.Get] %s StatusCode:’, dateformat(new Date(), "yyyy-mm-dd h:MM:ss"), res.statusCode); }).on("error", function(error) { console.log(‘[HTTPS.Get] %s Error:’, dateformat(new Date(), "yyyy-mm-dd h:MM:ss"), error.message); }); } catch(e) { console.log(‘[HTTPS.Get] %s Error:’, […]
Need to know where is located your PHP.ini file? Locate PHP.ini with Find The best way (in my opinion) is to use “find” to locate the php.ini: find / -name php.inifind / -name php.ini You should get something like this: /etc/php/7.3/fpm/php.ini /etc/php/7.3/cli/php.ini/etc/php/7.3/fpm/php.ini /etc/php/7.3/cli/php.ini So this way you will locate PHP.ini for both PHP7 FPM and […]
First edit your PHP.ini file to make sure display_errors is enabled: display_errors = ondisplay_errors = on Then if you changed this value, you’ll need to restart PHP7-FPM process: /etc/init.d/php7.3-fpm restart/etc/init.d/php7.3-fpm restart Additionally you may prepend these lines on your PHP script: error_reporting(E_ALL); ini_set(‘display_errors’, 1); ini_set(‘display_startup_errors’, 1);error_reporting(E_ALL); ini_set(‘display_errors’, 1); ini_set(‘display_startup_errors’, 1);
For PHP < 5.3 use this: echo realpath(dirname(__FILE__) . '/..');echo realpath(dirname(__FILE__) . '/..'); For PHP 5.3 to 5.6 use this: echo realpath(__DIR__ . '/..');echo realpath(__DIR__ . '/..'); For PHP >= 7.0 use this: echo dirname(__DIR__, 1);echo dirname(__DIR__, 1); References: https://www.php.net/manual/en/function.dirname.php
A simple way to save a string (or whatever) to a file in Python is: file = open(‘File.txt’, ‘w’) file.write(‘whatever’) file.close()file = open(‘File.txt’, ‘w’) file.write(‘whatever’) file.close() An alternative method that auto-closed the file is: with open(‘File.txt’, ‘w’) as file: file.write(‘whatever’)with open(‘File.txt’, ‘w’) as file: file.write(‘whatever’)
In Python you can get the current date and time like this: import time timestr = time.strftime("%Y-%m-%d_%H-%M-%S") print(timestr)import time timestr = time.strftime("%Y-%m-%d_%H-%M-%S") print(timestr) Here is an example output: 2019-08-11_15-23-022019-08-11_15-23-02 Then you can use timestr variable as file name, i.e: file = open(timestr+’.txt’, ‘w’) file.write(‘whatever’) file.close()file = open(timestr+’.txt’, ‘w’) file.write(‘whatever’) file.close() Or another example below: with […]
