Function returns array - PHP - php

Question

I have this class:
class Dados{
function cadastro($store){
preg_match_all('#<div align=\'left\'>(.*?)</div>#s',$store,$dados);
return $dados[1];
}}
And this is the output of print_r($dados->cadastro($pagina_cadastro));
Array
(
[0] => 02A
[1] => M
[2] => 72 - CIÊNCIA DA COMPUTAÇÃO/N
[3] => 1402
[4] => 23/12/2013
[5] => 6/7/1995
[6] => S
[7] => M
[8] => Details Removed
[9] => Details Removed
[10] => Details Removed
[11] => Details Removed
[12] => Details Removed
[13] => Details Removed
[14] => My Email
[15] => Details Removed
[16] =>
[17] => Details Removed
[18] => Details Removed
)
Details were removed to protect my privacy
So the question is, how can use echo to print just positions 3, 7 and 9 (for example) ?
I already try $dados->cadastro[1]($pagina_cadastro); and $dados->cadastro($pagina_cadastro)[1]; but any works.
I think it's a newbie question but I really need help.
Thank you so much!

Answer 1

Assign the result to a variable first:
$details = $dados->cadastro($pagina_cadastro);
and then you can get any position you want by:
echo $details[3];
echo $details[7];
echo $details[9];

Answer 2

may be try like this:
$val = $dados->cadastro($pagina_cadastro);
echo $val[3];// similarly other also.

Answer 3

if this
<?php
class Dados{
function cadastro($store){
preg_match_all('#<div align=\'left\'>(.*?)</div>#s',$store,$dados);
return $dados[1];
}
}
$var = new Dados();
print_r(var->cadastro());
?>
returns your array.
Then you do like this
<?php
//Previous code before this
$array = var->cadastro();
echo $array[7] . $array[9]; //etc
?>
To specify specific values

Answer 4

Just assign your function call to a variable like this:
$var = $dados->cadastro($pagina_cadastro);
Then you can print any index of the array like this :
print $var[3];
print $var[7];
print $var[9];
