if there are unknown number of newlines repeating like (\r\n\r\n\r\n) in a post var and if I want to change them to a SINGLE newline, what kind of an iteration should be used? The message may like below in DB and as you see the \r\n newline codes may repeat severaltimes and should be changed to only one SINGLE newline and after read from DB it will be easily coverted to BR tag by nl2br($foo) func.
KIRKUK, Iraq (AP)\r\n\r\n - Iraqi engineers have fixed most of the damage caused by a sabotage attack earlier this month on the main pipeline that carries Iraqi oil to Turkey, but the country is still depending on a network of substitute lines to export crude, an official with the North Oil Co. said Monday. \r\n\r\n\r\n\r\n The official said 75 percent of the work has been done but few more days are needed for the 40-inch pipeline to be ready for exports to the Turkish port of Ceyhan. \r\nThe pumping rate is still down to 250,000 barrels a day from the normal average of 400,000 barrels, the official said on condition of anonymity. Exports will go back to normal when the line is fixed, he said.
