php - Array - Undefined offset even if i already defined it -

i have 2 pages, page 1 contains array this:

$error=array(); $error[]='first value'; $error[]='second value'; $error[]='third value';

page 2 utilize array values:

include 'page1.php'; echo '<p>'.$error[0].'</p>'; echo '<p>'.$error[1].'</p>'; echo '<p>'.$error[2].'</p>';

it should work, instead keeps showing error:

notice: undefined offset: 0 notice: undefined offset: 1 notice: undefined offset: 2

any idea?

from updated question, shows

$error=array(); if( !empty($_post['email']) && isset($_post['email']) ){ if (!filter_var($email, filter_validate_email)) { $error[] = 'emailul nu este valid!'; }else{ $email=$_post['email']; } }else{ $error[]='utilizatorul este obligatoriu!'; }

in included file, should check conditional logic doing var_dumps

var_dump($_post) , 'email' index.

perhaps status 'email' exists not beingness satisfied!

edited, showing original below...

often you'll find it's less error-prone utilize foreach loop.

foreach($error $err) { echo '<p>'.$err.'</p>'; }

also, may seek using instead of include file.php, using require('file.php') or require_once('file.php')
