When working with data from a form is common that there are leftover space due to an error at the time of entering data or behavior of a particular component, especially the data masks. This unnecessary space ends up being a problem when the data are entered into the database, consuming valuable space. To help in this scenario methods are used to remove these leftovers given string.

PHP in the TRIM method helps in time to eliminate remnants of a string, see example:

<?php
$var = ” Name LastName “;
echo (trim($var));
?>

The result of this operation will be “Name LastName”, realize that there was the exclusion of additional space on both the left and right.

In another method format TRIM is possible to specify which characters will be removed, such as:

<?php
$var = ” Name LastName nnn”;
echo (trim($var, “n”));
?>

The result of this operation will be ” Name LastName “.

LTRIM

This method works just like TRIM, but it deletes all the leftover space on the left side only, check the example:

<?php
$var = ”  Name LastName  ”;
echo (ltrim($var));
?>

The result of this operation will be ” Name LastName”.

RTRIM

This method works in the opposite way to LTRIM, it deletes all the leftover space on the right side only, check the example:

<?php
$var = ”  Name LastName  ”;
echo (rtrim($var));
?>

The result of this operation will be “Name LastName “.

php

As in RTRIM, LTRIM and RTRIM methods also have a format in which the character can be informed.
