With the help of the staff here in the stack, I've set up a function where I treat a string.

I'll post the code and explain the problem.

Function:

function mb_str_pad($input, $pad_length, $pad_string = ' ', $pad_type =    STR_PAD_RIGHT, $encoding = "UTF-8") {
$diff = strlen($input) - mb_strlen($input, $encoding);
return str_pad($input, $pad_length + $diff, $pad_string, $pad_type);
}

Example, when I call the function like this:

echo mb_str_pad("ESPERANÇA", 15, "#");

It returns me:

ESPERANÇA######

Well the problem starts when you put a word that contains more than 15 letters, I need it to cut the word. Example of how to stay:

echo mb_str_pad("ESPERANÇAaaaaaaaaaaa", 15, "#");

It has to return like this:

ESPERANÇAaaaaaa

In other words, if he goes over 15 characters he has to cut and ignore everything on the right.

Can anyone help me with this?

Using the substr function, you pass three parameters: The string to be cut, the position of number of characters to be cut.

function mb_str_pad($input, $pad_length, $pad_string = ' ', $pad_type =    STR_PAD_RIGHT, $encoding = "UTF-8") {
    $diff = strlen($input) - mb_strlen($input, $encoding);
    return substr(str_pad($input, $pad_length + $diff, $pad_string, $pad_type),0,15);
}

echo mb_str_pad("ESPERANÇAaaaaaaaaaaa", 15, "#");

Use strlen to get the size and substr to determine the beginning and end of the string

<?php

function mb_str_pad($input, $pad_length, $pad_string = ' ', $pad_type =    STR_PAD_RIGHT, $encoding = "UTF-8") {
$diff = strlen($input) - mb_strlen($input, $encoding);
$str = str_pad($input, $pad_length + $diff, $pad_string, $pad_type);
$tam = strlen ( $str );
return ($tam > 15 ) ? substr($str, 0, 15) : $str;
}

echo mb_str_pad("ESPERANÇAaaaaaaaaaaa", 15, "#");
?>
