I'm trying to loop in the second array with this code
<?php
foreach ($categories[1] as $category_cat) { ?>
<li><span><?php echo $category_cat['name']; ?></span></li>
<?php } ?>
And I get the "Illegal string offset in..." error. I know that addind the [1] the the foreach might be the error but how I could make the loop in the second array then ?

i am using mongodb and my query returns only a key value
the following is the format of the var_dump

I do not want key . all i want is a array of values without a loop.
Solved it.
array_column($arr,"sno")
Do you know a good method or tips on how do I retrieve the values (as string) from this multi dimensional array:
array (size=5)
0 =>
array (size=1)
'email' =>
array (size=1)
0 => string 'lavidabonita#gmail.com' (length=27)
1 =>
array (size=1)
'email' =>
array (size=1)
0 => string 'iancasillasbuffon#gmail.com' (length=27)
2 =>
array (size=1)
'email' =>
array (size=1)
0 => string 'eddynvg#hotmail.com' (length=19)
3 =>
array (size=1)
'email' =>
array (size=1)
0 => string 'dolphin23#dolphin.net' (length=21)
4 =>
array (size=1)
'email' =>
array (size=1)
0 => string 'dolphin#dolphin.org' (length=19)
try with this:
function fn($arg){
foreach ($arg as $key => $val){
if (is_array($val)){
fn($val);
}
else{
echo "$key : $val\n";
}
}
}
fn($data);
I have var_dump() variable $fruit_array as below:
array (size=3)
0 =>
array (size=1)
'fruit_id' => string '2' (length=1)
1 =>
array (size=1)
'fruit_id' => string '1' (length=1)
2 =>
array (size=1)
'fruit_id' => string '3' (length=1)
I need to rename fruit_id to id and convert array string value to integer, example result:
array (size=3)
0 =>
array (size=1)
'id' => int 2
1 =>
array (size=1)
'id' => int 1
2 =>
array (size=1)
'id' => int 3
How can I do that ? thanks
You can do something like this:
<?php
foreach ( $array as $k=>$v )
{
$array[$k] ['id'] = intval( $array[$k] ['fruit_id'] );
unset($array[$k]['fruit_id']);
}
I've got a very large JSON file that I've converted into an array. The code you see below is the result of
var_dump($array['talents'])
(for those wondering, yes, this is me attempting to use Blizzard Entertainment's API)
Maybe I just missed that day at PHP school, but I just can't seem to remember or figure out how to get the values inside these deeper arrays. And perhaps more importantly, pay attention to the two 'spec' fields - ONE of them has a value of 'SELECTED: BOOLEAN TRUE', and the other does not. Basically, I need the NAME field from the array that has that SELECTED value.
To be honest, much as I love working in PHP, this multi-level thinking is a tad beyond me at the moment, I need some more experience. In the meantime, could anyone give me some tips, pointers, or just straight-up answers as to how I can get the value I need?
Thanks a bunch for your time!

print_r($array['glyphs']['major']);
So I have this array which the vardump looks like this:
array (size=4)
0 =>
array (size=1)
'field_4' =>
array (size=1)
0 => string 'item-1' (length=6)
1 =>
array (size=1)
'field_4' =>
array (size=1)
0 => string 'info-1' (length=6)
2 =>
array (size=1)
'field_5' =>
array (size=1)
0 => string 'item-2' (length=6)
3 =>
array (size=1)
'field_5' =>
array (size=1)
0 => string 'info-2' (length=6)
So I am trying to combine the array with the same key for example 'field_4' would be merge/combined into an array that has 2 items "item-1" and "info-1".
So the end result I would like is this:
array (size=2)
0 =>
array (size=1)
'field_4' =>
array (size=2)
0 => string 'item-1' (length=6)
1 => string 'info-1' (length=6)
1 =>
array (size=1)
'field_5' =>
array (size=1)
0 => string 'item-2' (length=6)
1 => string 'info-2' (lenght=6)
So is there a PHP convenience function to handle this or do I have to rebuild the array?
Thanks for looking.
Just iterate over the input array, building the merged array:
$merged = array();
foreach ($input as $a)
foreach ($a as $k => $v)
foreach ($v as $v2)
$merged[$k][] = $v2;
And then flatten it into your weird required output:
$flattened = array();
foreach ($merged as $k => $v)
$flattened[] = array($k => $v);
Input:
$input = array(
array('field_4' => array('item-1')),
array('field_4' => array('info-1')),
array('field_5' => array('item-2')),
array('field_5' => array('info-2')),
);
Output:
array(
array('field_4' => array('item-1', 'info-1')),
array('field_5' => array('item-2', 'info-2')),
)
When dumping output, print_r or var_export make for a much more readable example than var_dump
