Re: [PHP] Sorting...

[Francisco M. Marzoa Alonso]

If each element of the array is a string with those contains, it should 
be sorted as you want just calling sort function. It will considerate 
also rest of characters, of course, but the most significative should be 
the first ones.

Another alternative is to wrote a quicksort function in PHP customized 
by yourself, but I cannot figure out if this will be faster (probably not).

I have an array filled with CSV data...
array (

        20041115, Title, Author
        20040513, Title, Author
     )
where each array element is 1 line from the csv. When I go to print it
out, Im going to explode each by , and then print it out the way I like.
BUT, I want to sort them all by those first 8 digits, which happen to be
the date. Any way to sort an array by the first x characters in its
string?
This would save a lot on processor time, otherwise Im going to have to
pull an array of those characters, sort it, and then run some matching
scheme against the CSV data to print it in the order I like - which would
be HUGELY processor intensive.
Thanks,
