I have a string given in the following format:

a:1:{i:2;s:1:"0";}

I don't know why it's like that, but it is and I can't change it.

The letters do not change, but the numbers (i.e. the 1, 2, 1, and 0) do change and can be any positive value. I need to extract the numbers from the string and put them in an array.

How can I do this?

Thanks

That string is a serialized array.

PHP Code:

print_r( unserialize('a:1:{i:2;s:1:"0";}') ); 


yields:

Array
(
    [2] => 0
)

Hi, thanks so much for your reply!

I'm a little confused by something. Once I unserialize the string and get this:

Array
(
    [2] => 0
)

How is the first item in the array at index 2? Shouldn't there be something at index 0 and 1? Like this:

Array
(
    [0] => 0
    [1] => 0
    [2] => 0
)

PHP arrays are actually maps. Indexing is always done by key, not position.

PHP Code:

$foo = array( 2 => 1, 0 => 2, 1 => 3 );

print_r($foo); 


Array
(
    [2] => 1
    [0] => 2
    [1] => 3
)

Thanks
