Question

During the execution all errors are saved into an array like this:

$this->errors[$section] = $e->getMessage();

The thing is that, after the execution, I have to publish all sections included the ones that experimented an error concatenated with the error. When I try to to:

echo $this->errors[$section];

this is the warning I get:

Warning: Illegal offset type in ....

The solution described at Dynamic access to a PHP array didn’t help.

Answer 1

Check to see if the index is valid before using it:

if (array_key_exists($section, $this->errors) ) { 
    echo $this->errors[$section]; 
}
