formatting a string with str_pad

Guys with the help of the stack people here, I set up a function where I do the processing of 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 so: 

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

She returns to me:

ESPERANÇA######

Well, the problem starts when you put in a word that contains more than 15 letters, I need her to cut the word. Example of what it should look like:

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

You have to return like this:

ESPERANÇAaaaaaa

In other words, if you pass 15 characters, you have to cut and ignore everything on the right.

Can someone help me with that?

Using the function replace, you pass three parameters: The string to be cut, the start position and the amount of characters to 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, "#");

Uses strlen to take the size and substr to determine the start 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, "#");
?>

  • Well that way it almost worked, but I need to capture the value that I pass when I call the function mb_str_pad for in every place I call her, he possesses a different value.

  • blz put it like this substr($str, 0, $pad_length);

  • Well, I’m glad I helped in some way. :)
