Multi tool use

printing data a specific number of times with respect to a const and string length

Let there be a sring $str with any number of characters and $cons=25, also $rest=$cons-strlen( $str ).

$str

$cons=25

$rest=$cons-strlen( $str )

Now i wanted to print the string inside boxes so i made a loop where it catches the characters inside the string and echo it inside a div with class w3-border

Css:

.w3-border
{
border: 1px solid #f1e1d4 !important;
width:16px !important;
height:25px;
border-collapse: collapse;
float: left;
}


Php:

echo'<div class="w3-container" style="margin-bottom:5px !important">';
$str = $row['address'];
$strlen = strlen( $str );
$rest=$cons-$strlen;
echo'<div class="w3-left" style="width:150px">Address</div>';
for( $i = 0; $i <= $strlen; $i++ ) {
$char = substr( $str, $i, 1 );
echo '<div class="w3-border w3-center">'.strtoupper($char).'</div>';
}
if($rest>0)
{
for($i=0;$i<$rest;$i++)
{
echo '<div class="w3-border w3-center">&nbsp;</div>';
}
}
echo'</div>';


Now the above work fine if the number of character in the string is less that $cons, but there are more than that, i wanted to do that, it will print another '<div class="w3-border w3-center">&nbsp;</div>'until $second>0 ($second=$cons-$rest), $third>0 ($third=$cons-$second) and so on.

$cons

'<div class="w3-border w3-center">&nbsp;</div>'

I am having hard time figuring it out how to achieve so ? Any help/hint will appreciated.

A view of my problem -
i want the data of string to be printed inside boxes , in 1 line max 25 boxes if the data is smaller than 25 boxes then print the data and rest make it blank boxes to make upto 25 boxes like this

but if str is bigger than 25 then it goes to next line like this

so i want to do something that could make the second line complete upto 25 boxes, or if the data is upto third line then make boxes upto last so it should look clean , but i am no having any idea how to perfom it

$rest=$cons-$str

The modulo operator might be helpful here. It calculates (in this case) the remainder of strlen() / 25. Can you work it out from there?

strlen() / 25

Something along these lines may work, although I am not sure this is the exact solution -- didn't try it:

$rest = $cons - ($strlen % $cons);


EDIT:

After running the following code, I am convinced that the above solution should work. Or I may be misunderstanding your question...

<?php
$cons = 25;

$strlen = 24;
echo $cons - ($strlen % $cons). "<br>";
//Output: 1

$strlen = 26;
echo $cons - ($strlen % $cons);
// Output: 24
?>


$ rest = $cons - ($strlen % $cons)+1;

$rest

for($i=0;$i<$rest;$i++)

for($i=0;$i<=$rest;$i++)

$rest = $rest + 1
