Accessing arrays created dynamically with php

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.

You want to get all of the messages in the array? Or just a specific one? — Madara's Ghost

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

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

IF you haven't set $section, then PHP won't know what to return.

Assuming that your sections are arrays have some sort of ID number or string:

$errors[$section['id']] = $e->getMessage();
...
foreach($errors as $error){
    print_r($error);
}

I have a feeling that your problem is in the fact that $section is no longer set to what you want in the second code block.

I didn't - I saw you removed your comment and I wouldn't want to steal rep.

There's no indication in OP's question that $section is an array.

I take that back. It's the offset type that's illegal, and therefore may be due to $section having been defined as an array. You may be on to something here.

I think it's that $section isn't set properly in the second portion of the code, so OP needs to have some sort of ID to reference it properly.

Yes and no; OP just needs to make sure that its value is what he thinks it is before trying to access the index at value $section.
