Hello list :)
I have this problem, a certain string can contain the following information:
$string = '
hi{value1;value2}
bye{value1;value3}
hi{value1;value4}
hi{value1;value2}
bye{value1;value2}
';
What I want is to be able to get this result:
$string = '
hi{value1;value2}
bye{value1;value3}
hi{value1;value4}
bye{value1;value2}
';
(the order of appearance doesn't matter)
Is it even possible to do this with regular expressions? Or should I first
look if there is some kind of match and then apply an
str_replace($match,'',$string) and add the $match again?
Greetings !
Assuming the duplicate segments are identical.....
I'd use explode() and convert the string to an array. Use "}" for the delimiter.
Then use array_unique()
And then use implode() to restore the string.
