Fatal error: [] operator not supported for strings

by

You get this error when attempting to use the short array push syntax on a string.

For example, this

$foo = 'foo';
$foo[] = 'bar'; // ERROR!

I’d hazard a guess that one or more of your $name, $date, $text or $date2 variables has been initialised as a string.

Edit: Looking again at your question, it looks like you don’t actually want to use them as arrays as you’re treating them as strings further down.

If so, change your assignments to 

$name = $row['name'];
$date = $row['date'];
$text = $row['text'];
$date2 = $row['date2'];

It seems there are some issues with PHP 7 and code using the empty-index array push syntax.

To make it clear, these work fine in PHP 7+

$previouslyUndeclaredVariableName[] = 'value'; // creates an array and adds one entry

$emptyArray = []; // creates an array
$emptyArray[] = 'value'; // pushes in an entry

What does not work is attempting to use empty-index push on any variable declared as a string, number, object, etc, ie

$declaredAsString = '';
$declaredAsString[] = 'value';

$declaredAsNumber = 1;
$declaredAsNumber[] = 'value';

$declaredAsObject = new stdclass();
$declaredAsObject[] = 'value';

All result in a fatal error.
