PHP Delete all files older than x days in 2 folders

Question

I'm tring to use this code to delete all files older than x days in 2 folder but I'm getting an error:

PHP Parse error: syntax error, unexpected T_PUBLIC in E:\\home\\ca\\web\\cm\\cache.php on line 6

Why?

<?php
$pastas = array("gallery-images/","resources/cache/");
foreach($pastas as $pasta){
   $this->deleteFrom($pasta);
}
public function deleteFrom($path){
$expiretime=10080; //expire time in minutes, 7 days = 7*24*60

$tmpFolder=$path.'/';
$fileTypes="*.*";

foreach (glob($tmpFolder . $fileTypes) as $Filename) {

// Read file creation time
$FileCreationTime = filectime($Filename);

// Calculate file age in seconds
$FileAge = time() - $FileCreationTime;

// Is the file older than the given time span?
if ($FileAge > ($expiretime * 0)){

// Now do something with the olders files...

echo "The file $Filename is older than $expiretime minutes\n";

//delete files:
unlink($Filename);
}

}
}
?>

Answer 1

Your function definition is out of a class so you need to remove PUBLIC

public function deleteFrom($path){

to

function deleteFrom($path){

Also $this-> is not correct you need to remove them and call the function as

deleteFrom($pasta);

Check here how Public, Private etc are used in PHP http://php.net/manual/en/language.oop5.visibility.php

Answer 2

this is because not using class here , so no need to use $this to call your function just use deleteFrom() please see the code below

foreach($pastas as $pasta){
   deleteFrom($pasta);
}

Answer 3

If you want to use a class, you could write something like that :

$pastas = array("gallery-images/", "resources/cache/");

$File = new File();
foreach ($pastas as $pasta)
{
   $File->deleteFrom($pasta);
}

class File
{
  public function deleteFrom($path)
  {
    $expiretime=10080; //expire time in minutes, 7 days = 7*24*60

    $tmpFolder=$path.'/';
    $fileTypes="*.*";

    foreach (glob($tmpFolder . $fileTypes) as $Filename)
    {
      // Read file creation time
      $FileCreationTime = filectime($Filename);

      // Calculate file age in seconds
      $FileAge = time() - $FileCreationTime;

      // Is the file older than the given time span?
      if ($FileAge > ($expiretime * 0))
      {
        // Now do something with the olders files...
        echo "The file $Filename is older than $expiretime minutes\n";

        //delete files:
        unlink($Filename);
      }
    }
  }
}
