I have a string content.
$string = "FIRST he ate some lettuces and some French beans, and then he ate some radishes AND then, feeling rather sick, he went to look for some parsley.";
Here I want to take a specific string
"then he ate some radishes"
How can I do it with REGEX? I want it in REGEX only
I want to pass just 2 parameters like
1. then
2. radishes
so finally I want output like "then he ate some radishes"
You can use /(?<=then).*(?=radishes)/ to get everything between then and radishes.
$re = '/(?<=then).*(?=radishes)/';
$str = 'FIRST he ate some lettuces and some French beans, and then he ate some radishes AND then, feeling rather sick, he went to look for some parsley.';
preg_match_all($re, $str, $matches, PREG_SET_ORDER, 0);
var_dump($matches);
Break down:
(?<=then): Assert that the Regex below matches
then matches the characters then literally (case sensitive).* matches any character (except for line terminators)* Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy)(?=radishes): Assert that the Regex below matches
radishes matches the characters radishes literally (case sensitive)The requirement in OP is to match everything including then and radishes, so you can use /then.*radishes/ in place of /(?<=then).*(?=radishes)/
To make the regex non greedy, you should go for /then.*?radishes/ and /(?<=then).*?(?=radishes)/
/then.*radishes/ to match everything.Just simply use this
$string = "FIRST he ate some lettuces and some French beans, and then he ate some radishes AND then, feeling rather sick, he went to look for some parsley.";
preg_match("/then(.*?)radishes/", $string, $matches);
echo $matches[0];
