PHP - on correct arrangement on spacing on php : Need help on aligning the space on php, when i try to output it for textfile. i always got this.

20FIRSTNAME1             LASTNAME1        LNUMBER1

20FIRSTNAME2          LASTNAME2        LNUMBER2

20FIRSTNAME3        LASTNAME3        LNUMBER3

The correct output must be this. it should be align.

20FIRSTNAME1      LASTNAME1        LNUMBER1

20FIRSTNAME2      LASTNAME2        LNUMBER2

20FIRSTNAME3      LASTNAME3        LNUMBER3

I used substr to output to it.
