Reading characters in from a string

[adamgeorge]

Hello everyone.

I have a String, and I want to be able to examin each character in it one at a time.

how do I do this? I know it in java but can't figure it out in php.

I have a great big string... and it contains html. I want to count all the characters that are between the tags. So.. I guess you just go through each character... determin if it's part of a tag, and if not increment the counter.

hmm... but how do read in one character at a time?

I've been trying to do it with the substr() function... and it's going to be terably inificient I'm sure...

does anyone know a good way to go about this in php?

thanks 🙂

I'm a 'newbie' myself, but my understanding is that you can treat it just like a char * in 'c', as in:

$mystring = 'hello there'

for ($i = 0; i< 5; i++)
echo $mystring[$i];

$counted='Hello';
$count=sizeof($counted);

This doesn't give an array of characters, and it oughta be strlen() anyway.

Thanks man. yeah... that's how you do it. I didn't realise strings were treated as arrays in php as well..

cools...
