Question

I’m writing a parser and I need to extract words that are between double pipes using php

For example I want to extract the ‘ipsum’ from the string below

Lorem ||ipsum|| blah

If there are multiple words between double pipes, they should be extracted as well

Clarification

When I say multiple words I don’t mean this: ||word another word||

I mean this

||Word1|| blah blah (newline)
blah ||Word2||

Clarification part 2

the ||quick|| brown fox ||jumps|| over the lazy ||dog|| 

What should be extracted should be the words ‘quick’, ‘jumps’ and ‘dog’

Sorry for the confusion… There probably are some right answers below, I’ll pick one once I confirm it tomorrow at work 🙂

Answer 1

Try this:

if(preg_match('/\|\|(.*)\|\|/', $str, $matches) === 1){
    echo $matches[1];
}

Or if there are multiple ||, try this:

if(preg_match_all('/\|\|(.*?)\|\|/', $str, $matches) !== FALSE){
    print_r($matches[1]);
}
