Regexps: How to return multiple matches

[Mike Lewis]

I am using a regular expression to return a substring .... something like this:

$source = ' blah blah blah [b]Fruit=Apple;[/b] blah
 blah [b]Fruit=Orange;[/b] blah blah [b]Fruit=Tangerine[/b]; blah ';

$pattern = 'Fruit=[A-Za-z]*;';
eregi($pattern, $source, $fruit);
echo $fruit[0];

(The bold text in the above code is just so that you can easily see the items I want to find.)

The above code correctly returns the first of the fruit. My question is: How do I retrieve the subsequent occurrences? Is there an easy way to do that using regexps?

Thanks in advance.

Mike

Hi

$pattern = "/Fruit=[A-Za-z]*;/";
[url=http://php.net/preg_match_all/]preg_match_all[/url]($pattern, $source, $fruit);
print_r($fruit);

Feherke,

That looks like it's exactly what I want. Many thanks.

I haven't used the preg_ functions before. Maybe I should I should go with them from now on (unless there are any disadvantages?).

Thanks for that, Feherke. I don't think the limitations will affect me, but I'll keep it in mind.

As of php 6 the preg library will be preloaded at runtime. so i see less and less disadvantage in using regex.

coupled with that, i've always thought that the effort of coding around a problem of minor system performance issue was never worth the equivalent cost of shoving another linux box in the mix! at least with interpreted languages.
