Split an array, not working

Question

Hi

OK I need to figure out how to count how many numbers are in the following example.

07000000000,07000000001,07000000002,07000000003,07000000004 etc...

I have tried the following PHP functions.

explode, implode, count, foreach and for.

None of them seemed to have worked and I am really stuck now.

Any help will is appriciated.

Answer 1

Well, this might not be the -best- way to do it, but...

Could you just iterate for each character on the string and count the number of commas, and add 1? I mean, this requires that the string is properly formatted to be number,number,number but if you can verify that it is formatted that way, this is way to make it work.

Again, this might not be the best way (I'm not much of a php guy), there's probably better ways. But if what you're doing isn't working, maybe this will.

Answer 2

simple solution using explode and count:

echo count(explode(',', $string));

but you might get better performance with some regex, counting the matches, for example by using preg_match—it will return the number of matches

echo preg_match('/,/', $string);

Answer 3

Did you write your explode like this?

$array_of_numbers = explode(',', $string_of_numbers);
$count_of_numbers = count($array_of_numbers);

Answer 4

$count = substr_count($string_of_numbers,',')+1;
