Cannot use string offset as an array in php

Question

I\'m trying to simulate this error with a sample php code but haven\'t been successful. Any help would be great.

\"Cannot use string offset as an array\"

Answer 1

I was able to reproduce this once I upgraded to PHP 7. It breaks when you try to force array elements into a string.

$params = '';
foreach ($foo) {
  $index = 0;
  $params[$index]['keyName'] = $name . '.' . $fileExt;
}

After changing:

$params = '';

to:

$params = array();

I stopped getting the error. I found the solution in this bug report thread. I hope this helps.
