Question

i have a one string of 75 charater and it display in 3 line how i display in 3 line in php pl help

Answer 1

If I understood the question correctly you are looking for wordwrap

<?php
// a string with 75 characters
$x = str_repeat('x', 75); 

echo wordwrap($x, 25, '<br />', true);

edit: if your string contains whitespace wordwrap() might break the string into smaller pieces.
Then you need something like str_split.

<?php
// a string with 75 characters including spaces
$x = str_repeat('x y', 25); 
echo join('<br />', str_split($x, 25));
