Asynchronous PHP function calling

Question

I have a function that writes it into a file.

public function write($type = "error", $mensaje = "") { 
    $this->file = fopen($this->filePath.$this->fileName, "a+"); 

    if ($this->file == null) { 
        trigger_error("Error: No file", E_USER_ERROR); 
    } else { 
        fwrite($this->file, $type." ".$mensaje."\n");
    } 
}

I need to call this function from another php file say index.php

function test() {
    write("testing done");
    echo "done";
}

I want the write function to be called from index.php asynchronously so the current execution doesn't stop or block if the write fails.

Write the above function in a class and call the class to the index.php — Sobin Augustine

Unfortunately, PHP does not support multithreading so there is not really a way to do this easily. You could build something using cron or something, but that would be too broad to explain here. That being said, your write function doesn't look so bad to just call it in the main thread. — Bart Friederichs

maybe use pthreads, check this: stackoverflow.com/a/27364939/1855357 — Sobin Augustine

with phptreads ( http://php.net/manual/en/intro.pthreads.php ), something like

class writerThread extends Thread {
public function __construct($type="error",$message=''){
  $this->type=$type;
$this->message=$message;
}

public function run(){
   file_put_contents($filename,$this->type.$this->message);
}
}

$writer=new WriterThread("testing done");
$writer->start();
