php extract string



this means that the substring from to the total length of the string will miss the number of characters in the end matching the number of newlines in the string. to fix this one can add the s modifier (pcre_dotall) in the pattern:   parameter, description. string, required. specifies the string to return a part of. start, required. specifies where to start in the string. a positive number start at a specified position in the string; a negative number start at a specified position from the end of the string; start at the first character in string. length, optional. might be a lazy approach, but in such cases i usually would first explode my string like this: $string_array = explode("=",$string);. and in a second step i would get rid of that "]" maybe through rtrim: $id = rtrim($string_array[], "]"); but this will only work if the structure is always exactly the same cheers.
