PHP check website online or offline issue -

-

this works checking whether website online:

<?php $host = 'http://jdfhgjfdhjanmczxmcnaushdfjsa.com'; if($socket =@ fsockopen($host, 80, $errno, $errstr, 30)) {         echo 'true'; fclose($socket); }else{     echo 'false';  }

but when try check multiple sites, not work. return false. why?

<?php $hosts = array(); $hosts[] = 'jdfhgjfdhjanmczxmcnaushdfjsa.com'; $hosts[] = 'google.co.il';   $i = 0; foreach($hosts $host){     $i++;     if($socket =@ fsockopen($host[$i], 80, $errno, $errstr, 30)) {         echo 'true'; fclose($socket); }else{     echo $host.' false';  }    }

the reason 2nd code doesn't work not accessing hosts correctly

change

if($socket = @fsockopen($host[$i]...)

to

if($socket = @fsockopen($host...)

you don't need $i index. can rid of altogether.

addendum

you noted when first posted calling in loop wasn't working calling 1 domain worked. fix above solution original question. you're facing different problem: missed because added error suppression operator @ in front of function call. removing shows problem:

fsockopen() has been disabled security reasons

online sandboxes disable fsockopen, cannot rely on output determine whether code works. way it's bad idea use error suppression, particularly in development.

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
