[SOLVED] 2 separator string to array

[jeffz2008]

Here's the string: 

 

415{3}8{1}1{6}35

 

I'm trying to:

1. drop first element - 415

2. convert rest of string to an array in this way:

 

array([3]=>8 [1]=>1 [6]=>35)

 

Seems simple enough, but somehow I do something wrong.

Here's what I try to do:

 

$s = explode('{', '415{3}8{1}1{6}35');

I get:

Array ( [0] => 3}8 [1] => 1}1 [2] => 6}35 )

 

I tried to walk this array using foreach and exploding values, but I can't find (so far) a way to actually get this:

 

Array ([3]=>8 [1]=>1 [6]=>35)

 

Any thoughts which can put me on a right track?

Thanx in advance.

$string ="415{3}8{1}1{6}35";
print_r( preg_split("/\{\d+\}/",$string) );

ghostdog74 thank you - I will definitely have to explore regex.

 

Your solution gets this:

 Array ( [0] => 415 [1] => 8 [2] => 1 [3] => 35 ) 

 

while I look to accomplish this:

 Array ([3]=>8 [1]=>1 [6]=>35) 

 

Inside of curly braces become keys and what follows, becomes values of a new array

 

Anyone has an idea?

print_r( preg_split("/\{\d+\}/",substr($string,2)));

Thank you thorpe.

Your solution brings this:

 Array ( [0] => 5 [1] => 8 [2] => 1 [3] => 35 ) 

 

I was actually looking for this:

Array ([3]=>8 [1]=>1 [6]=>35)

 

I actually did it this way (not very elegant/compact, but does the job).

$entry_array = '415{3}8{1}1{6}35';
$str = str_replace(array('{','}'),',',$entry_array);
$array = explode(',',$str);
array_shift($array);

foreach ($array as $k => $v)
	{
		if (!is_odd($k)) $key_array[] = $v;//even
		if (is_odd($k)) $val_array[] = $v; //odd
	}	
    //for loop below is for PHP4
    //PHP5 has function for it: array_combine
    for ($i=0, $n=sizeof($key_array); $i<$n; $i++) 
	{
		$new_array[$key_array[$i]] = $val_array[$i];
	}

print_r($new_array);

 

A little function is needed here (checks even/odd - only if array_combine is not used):

function is_odd($number) {
   return $number & 1; // 
}
