looping array issue.

[doomie]

Hello Everyone,

I got stuck. I have a headache already, please help.

Problem is. Array example:

$part[0][0] = "value1";
$part[0][1] = "1";

$part[1][0] = "value2";
$part[1][1] = "1";

$part[2][0] = "value3";
$part[2][1] = "2";

$part[2][0] = "value4";
$part[2][1] = "2";

$part[3][0] = "value5";
$part[3][1] = "3";

 

I am looping this array with for loop. In loop i need to call a function when $part[$i][1] changes. I tried to do something like this:

 

$ch ="";
for ($i=0;$i<count($part);$i++)
{ 
            //making an array here based on $part[$i][0], let's call it $data.
    
    if($ch != $part[$i][1])
    {
         function insert($data);
         $ch = $part[$i][1];
    }
}

 

But then the function is inserting $data gathered for $part[0].

 

The question is: What should i to make that insert function to be called when $part[$i][1] changes ??

How you have setup your for loop is correct. However it can be cleaned up with a foreach loop

function insert($data)
{
echo "inserting... $data<br />";
}

$prev = '';
foreach($part as $data)
{	
if($prev != $data[1])
	insert($data[0]);

$prev = $data[1];
}

 

What are you planning on doing with the insert() function?

"Insert" function is just inserting $data into a csv file. The problem is that i want to insert just then when $part[$i][1] changes and after looping all values.

Your example does not work. Because before "if" i am making an array. And with function i do insert an array - not a value and not the array i am looping. To be more clearly i want him to make the array then to call insert function.
