Problems with array

Question

I can’t see the problem here. I have an array, and I would like to take out the information I need, by using this code, but I doesn’t seems to be working, and I don’t know why:

$member = array_slice($members, 0, 1); 
print_r($member);

$event=($member["title"]);
$content=($member["content"]);      
$day=($member["day"]);
$month=($member["month"]);
$year=($member["year"]);

Array ( 
    [0] => Array ( 
        [title] => Daniel Ryan 
        [content] => Daniel-Ryan Spaulding is an Internationally-Touring Canadian Stand-Up Comedian, who has performed extensively in 35 countries worldwide.

`var_dump()` and `print_r()` work similarly as diagnostic tools. — Ulrich Eckhardt, Jun 01 '14 at 13:53

Array ( [0] => Array ( is the part you're missing. You basically have

array(
    array(
        'title' => 'Dan Ryan',
    )
)

As a suggestion, don't use array_slice to extract a single-element subarray but simply use $members[$i] to extract a single element.

This may help you

$event=($member[0]["title"]);
$content=($member[0]["content"]);      
$day=($member[0]["day"]);
$month=($member[0]["month"]);
$year=($member[0]["year"]);

your array is two dimensional your data title,content etc is contains inside Array $member[0] that is the reason it gives you error of undefined index

You're starting with an array of arrays. array_slice() returns an array, albeit in this case of just one element, which is itself an array.

Either change the first line to

$member = $members[0];    // Get the first element of $members

or change the indexes to

$event=($member[0]["title"]);
$content=($member[0]["content"]);      
$day=($member[0]["day"]);
$month=($member[0]["month"]);
$year=($member[0]["year"]);
