Part of a string into a variable

[bknowles]

Hey all, i have a quick (?) question about some string manipulation.

I've got a string, somewhere inside of which lies the text {RP_VAR_something}. The "something" is going to be a chunk of text with no spaces.

What i need to do is parse that main string, and copy out the {RP_VAR_something} chunk into a variable. So, for example, if i had a string like:

$str = "bob vila is comming to eat your brain you {RP_VAR_doofus}";

I would need to parse that string and get {RP_VAR_doofus} into a variable of its own.

Note i do not want to alter the initial string.

Any ideas? Any help would be greatly appreciated, thanks.

Hi!

This should work:

<?PHP
function findDbvalue($text, $startkey, $endkey) {
## Explode first by { to  ##
$codeEnd = explode("$endkey", $text);
$codeStart = explode("$startkey", $codeEnd[0]);
$db_text = $codeStart[1];
## Return the value between keys ##
return $db_text;
}
## For your example ##
$str = "bob vila is comming to eat your brain you {RP_VAR_doofus}";
## The function returns everything between { and } ##
$return_val = findDbvalue($str, "{", "}");
echo "String: $str<br><br>dbvalue: $return_val";
?>
