Foreach loop is not working in cronjob in php

Question

I have written a script to check only CSV files and delete them.

$dir = $getData['ftp_location']; //get the dir locations from db
echo $dir;
echo nl2br("\n"); 

$files = glob("$dir/*.csv"); //get only csv files

echo $files;
echo nl2br("\n");

foreach ($files as $tmpname)
{
   //do some stuff. I have also done echo here it is not working.
   echo "File Deleted";
}

So I tried a simple foreach code like this:

$colors = array("red", "green", "blue", "yellow");

foreach ($colors as $value) 
{
      echo "$value <br>";
}

Note: On every run, I get an email stating cronjob ran successfully with the echo printed.

Email like this:

./files/pvc/
Array

I don't get the echo inside the foreach loop.

Like "file deleted" or "colors"

If I run the same code directly it is working fine but not via cronjob. Any idea why?

Answer 1

Because csv path is relative path.

When cron is executed, the current directory path is the same as the php binary path(ex: /usr/bin/php).

Please use the absolute path.

$dir = __DIR__. DIRECTORY_SEPARATOR. $getData['ftp_location']; //get the dir locations from db
