Ok, so here it goes:
I have a variable:
$var = ":12:3{this is a test}:5:8{this is another test}:"
Everything between : : is a separate value, which I can easily extract in an array:
$value=explode(":",$var);
I then get:
$value[0]=12
$value[1]=3{this is a test}
$value[2]=5
$value[3]=8{this is another test}
RE values like $value[1] and $value[3] with brackets, I would like to extract the number before the bracket '{' in one variable, and then all the text between the brackets {} in another variable, which should result in something like this:
$key=3
$keytext=this is a test
How can I achieve this?
I am sure this one will be dead simple for PHP experts, so many thanks in advance!

Re: extract various texts from a string variable
What is the format of that string? Where is it coming from? Is it JSON?

Anyway, here is the solution for it:

Anyway, here is the solution for it:
Code: Select all
$string = '3{this is a test}';
preg_match('#^(\d+){([^}]+)}$#', $string, $matches);
list(, $key, $keytext) = $matches;
