Exception has occurred.
Fatal error: Array and string offset access syntax with curly braces is no longer supported.
Open the PHPExcel/Shared/String.php
find the following in autoloader
if ($bom_be) {
$val = ord($str{$i}) << 4;
$val += ord($str{$i+1});
} else {
$val = ord($str{$i+1}) << 4;
$val += ord($str{$i});
}
change to
if ($bom_be) {
$val = ord($str[$i]) << 4;
$val += ord($str[$i+1]);
} else {
$val = ord($str[$i+1]) << 4;
$val += ord($str[$i]);
}
You are getting this error because of php version.
replace curly brackets with square brackets.
