Foreach and Array

[tqla]

Hello, I have an array called $data that looks like this.

 

Array
(
    [0] => Array
        (
            [0] => a
            [1] => b
        )

    [1] => Array
        (
            [0] => c
            [1] => d
        )

    [2] => Array
        (
            [0] => e
        )

)

 

I wish to do a foreach look on this part:

 

    [1] => Array
        (
            [0] => c
            [1] => d
        )

 

When I do

 

foreach ($data as $row)...

 

I get everything in the array.

 

When I do

 

foreach ($data[1] as $row)... or foreach ($data['1'] as $row)...

 

I get nothing.

 

What is the proper way?

 

Thanks.

Show us the actual code, what you're describing doesn't make much sense. You can also do a print_r() on the data to make sure it's the way you expected.

[tqla]

Obviously print_r prints this:

Array
(
    [0] => Array
        (
            [0] => a
            [1] => b
        )

    [1] => Array
        (
            [0] => c
            [1] => d
        )

    [2] => Array
        (
            [0] => e
        )

)

 

My question is how do do a foreach loop on this part:

 

    [1] => Array
        (
            [0] => c
            [1] => d
        )

[Jessica]

It's too bad I didn't write anything besides that part huh.

$myarray = array(
            array('a', 'b'),
            array('c', 'd'),
            array('e', 'f')
        );
        
foreach ($myarray as $row)  {
    foreach ($row as $x)  {
        echo  "$x "; 
    }
    echo '<br />';
}

 

result

a b

c d

e f

 

[tqla]

Thank you Barand. Can the loop be made to echo only "c d"?

[Jessica]

<?php
$myarray = array(
            array('a', 'b'),
            array('c', 'd'),
            array('e', 'f')
        );
        
foreach ($myarray[1] as $x)  {
echo  "$x "; 
}
?>

 

It works that way, which is why I said you need to post your code if when you attempt to do that, it doesn't work.

[tqla]

Ah ha. Thanks jesirose.

[Barand]

do you mean

 

foreach ($myarray[1] as $x) echo $x;

[tqla]

Yes I do Barand. Thanks again!

[Jessica]

I'm so confused...that's exactly what you said didn't work in your OP.

[Barand]

When I first read the OP I thought he probably had nested foreach loops both using (.... as $row)

[Jessica]

Must be.

[tqla]

I was using nested foreach loops. Worked fine if I wanted to echo everything. But I did not. Solution: one foreach, $data[1] as $row.

[Barand]

So long as you see your problem. If you have

 

foreach ( $whatever as $row) in the outer and the inner loop, the inner "as $row" is overwriting the $row in the outer loop.

[tqla]

Oh I know, I had no problem echoing the entire array as expected. Thanks Barand.
