I have an array like this:
$array = array(
user => "user1",
name => "name1",
books => "book1", "book2"
);
I want to go into books and check the value that elements have inside it, in case it would be 2 (book1 and book2). I already tried count (array ['books']); and array ['books']. length but none of these seems to work. I would like to do this check in an if.
Thanks for any input.
This is not an array inside another:
books => "book1", "book2"
To be an array would have to be like this (ps: put quotation marks around the keys too):
$array = array(
"user" => "user1",
"name" => "name1",
"books" => array( "book1", "book2" )
);
Or in php5.4 +:
$array = [
"user" => "user1",
"name" => "name1",
"books" => [ "book1", "book2" ]
];
Otherwise you did:
$array = array(
user => "user1",
name => "name1",
books => "book1", "book2"
);
It would be the same as:
$array = array(
"user" => "user1",
"name" => "name1",
"books" => "book1",
0 => "book2"
);
Aliais array['books'].length does not work in PHP, ie javascript probably does not work inside PHP.
See the example online working: link
The check in a if would be:
if (count($array['books']) == 2) {
echo 'Contém 2 elementos';
}
Or:
if (count($array['books']) > 1) {
echo 'Contém 2 ou mais elementos';
}
Sabrina, you can use a command called foreach
Your foreach would look like this
foreach ($array as $key => $value)
{
foreach ($value as $keys => $valor)
{
//aqui você pega seu valor
}
}
