count arrays

[phorcon3]

here's the code I have:

 

<?php

foreach($something as $item => $value)
{
if($value[1] == 'MN')
{
/*Here I already need to know the total number of arrays this code will output*/

echo '<td>'.$value[0].'</td>';
}
}

?>

 

I tried using:

 

<?php

$total_arrays = count($value[0]);

?>

 

or

 

<?php

$total_arrays = array_count($value[0]);

?>

 

but I just can't figure it out how to do it. I have to know the total number of arrays so I know when to insert a line break. I hope this makes sense.

 

I'd appreciate any help/comments on this. Thanks.

$total_arrays = count($something);

 

That it?

yah, but the problem is, i'm using the if function and i only need the total number of arrays meeting that specific requirement

 

$total_arrays = count($something);

 

will output the total of arrays, even those not meeting the if-requirement, which is for example

 

<?php

if($value[1] == 'MN')

?>

because what I am trying to do is, to create 3 columns. this code above might output 900 values meeting the requirement that the $value[1] == 'MN' and then I want to insert a line break at 300, so it will create 3 columns with the exact number of values... if that makes any sense lol

Can't remember this...still kinda sleepy.

 

$total_arrays = count($value);

 

or

 

$total_arrays = count($item);

[phorcon3]

lol sorry bout that, didnt mean to bug u that early in the mornin..

 

nah, that doesnt do it either..

 

$total_arrays = count($value); will output the number of slots in an array

 

<?php

$something = array(
'1' => array('slot1', 'slot2', 'slot3'),
);
?>

 

in my case 3

 

and

 

$total_arrays = count($item);

 

will just output 1

 

but thanks for ur help;)

 

i might as well just try to come up with a better way to do this...

echo count ($something[1]);

You didn't bother me. It's just early. I could very well not answer this if I wanted. So it's not your fault.

 

Is there only 1 array or are there more? If there are more, you probably want:

$total_arrays = count($something, COUNT_RECURSIVE) - count($something);

[phorcon3]

<?php

$something = array(
'1' => array('array1', 'MN'),
'2' => array('array2', 'MN'),
'3' => array('array3', 'MN'),
'4' => array('array4', 'MN'),
'5' => array('array5', 'MN'),
'6' => array('array6', 'MN'),
'7' => array('array7', 'MN'),
'8' => array('array8', 'MN'),
'9' => array('array9', 'AL'),
);

foreach($something as $item => $value)
{
if($value[1] == 'MN')
{
$total = count($something);

echo '<div>'.$value[0].' / total_arrays: '.$total.'</div>';
}
}
?>

 

this will output:

 

total_arrays: 9 even tho there are only 8 arrays meeting the requirement of $value[1] == 'MN'

 

that's the problem.

[phorcon3]

the crappiest coding i could think of is:

 

<?php

$count = '';
foreach($something as $item => $value)
{
if($value[1] == 'MN')
{
$count++;
}
}

foreach($something as $item => $value)
{
if($value[1] == 'MN')
{
echo '<div>'.$value[0].' / total_arrays: '.$count.'</div>';
}
}

?>

 

but that's just REALLY crappy coding, and it will use up alotta load time too, I'm guessing.. that's what sucks bout it

if you reorganise your array

 

$something = Array
(
    [array1] => MN
    [array2] => MN
    [array3] => MN
    [array4] => MN
    [array5] => MN
    [array6] => MN
    [array7] => MN
    [array8] => MN
    [array9] => AL
)

 

then

<?php
$k = array_count_values($something);

echo $k['MN'] ;     // 8

[phorcon3]

yah, but the problem is, my array looks actually completely different than the one above

 

<?php

$something = array(
'1' => array('info', 'MN', 'info', 'info'),
'2' => array('info', 'MN', 'info', 'info'),
'3' => array('info', 'MN', 'info', 'info'),
'4' => array('info', 'MN', 'info', 'info'),
'5' => array('info', 'MN', 'info', 'info'),
'6' => array('info', 'MN', 'info', 'info'),
'7' => array('info', 'MN', 'info', 'info'),
'8' => array('info', 'MN', 'info', 'info'),
'9' => array('info', 'AL', 'info', 'info'),
);

?>

 

but thanks anyway

Well in that case, you'll just have to loop through it the hard way. I don't know a short way to do this.

 

<?php

foreach($something as $item => $value)
{
$total = 0;
foreach($something as $b => $c) if($c[1]=='MN') $total++;
echo $total;
}

?>
