Question

I am trying to extract substring from string gettting from mysql database using substr function:

substr($mystring,$startpoint,$endpoint);

here start and end point can be any number.

But I am not getting gesired result. Ptart point works but something is wrong with end point.

What is reason?

Edit

when I am pasin start ans end point like 15 and 50, start point is working fine so resultant string is starting from 15th char of main string . but end point is not working it’s giving me meand end char in resultant string is not 50th of main string.

Answer 1

You should subtract $endpoint-$startpoint and pass it as third parameter to get desired output.

like below:

substr($mystring,$startpoint,($endpoint-$startpoint));
