this is my php project dir structure
My_Project
->cache
->config
->lib
TestClass.php
my TestClass.php contains method cacheSet(), it creates file within the cache/ dir. so my question is how I set path to CACHE_DIR within that method.
class TestClass{
.....
public function cacheSet($filename, $data)
{
$filename = CACHE_DIR . '/' . $filename. '.cache';
$file = fopen($filename, 'w');
fwrite($file, serialize($data));
fclose($file);
}
}
If you are using a class, you would most likely do this:
public function cacheSet($filename, $data){
$this->filename = CACHE_DIR . '/' . $filename. '.cache';
$this->file = fopen($this->filename, 'w');
fwrite($this->file, serialize($data));
fclose($this->file);
}
I am not 100% sure of this, but if it's in a class, then it would most likely be this. Then at the start of your class, before you do the class TestClass{ you would want to do something like $class = new TestClass();
You can use:
class TestClass{
.....
const CACHE_DIR = "your dir";
public function cacheSet($filename, $data)
{
$filename = CACHE_DIR . '/' . $filename. '.cache';
$file = fopen($filename, 'w');
fwrite($file, serialize($data));
fclose($file);
}
}
So you use const
