split string in php using regex

how can I split this string:

|^^^*|^^^*|^^^*|^^^*|^^^*|myvalue^nao^nao^nao*|myvalue^nao^nao^nao*|myvalue^nao^nao^nao*|^^^*|^^^*|^^^*|^^^*|^^^*|^^^*|^^^*|^^^*|^^^*|^^^*|^^^*|^^^*

so I can only get the value "mayvalue".

For the moment, I'm using:

$text = preg_split("/[^\|(*.?)\^$]/", $other);

But it returns myvalue^nao

Any ideas?

You could split twice, once on | and again on ^; if your big string is in $input, then:

$pipes = preg_split('/\|/', $input);
$want  = preg_split('/\^/', $pipes[6]);

Then $want[0] has what you're after. This would probably be easier than trying to come up with one regex to split with.

Since shesek hasn't come back I'll include their suggested approach. You can also use explode twice since you're working with simple delimiters:

$pipes = explode('|', $input);
$want  = explode('^', $pipes[6]);

and again $want[0] has what you're looking for.

This will get all "myvalue" and other strings placed after | and before ^ in an array, $matches[1]:

$text = preg_match_all("/\|(.*?)\^.*?\^.*?\^.*?\*/", $other, $matches);
