trim string in php codeigniter

To trim a string in CodeIgniter, you can use the trim() function provided by PHP. The trim() function removes whitespace and other predefined characters from both the beginning and the end of a string.

Here are the steps to trim a string in CodeIgniter:

1. Load the string helper: First, you need to load the string helper in CodeIgniter. The string helper contains various functions for manipulating strings. You can load the string helper by adding the following line of code in your controller or model:

php $this->load->helper('string');

1. Use the trim() function: Once the string helper is loaded, you can use the trim() function to remove whitespace from the beginning and end of a string. The trim() function takes the string as its parameter and returns the trimmed string.

php $trimmed_string = trim($string);

In the above code, replace $string with the actual string you want to trim.

After executing the above code, the $trimmed_string variable will contain the trimmed version of the original string.

That's it! Following these steps will allow you to trim a string in CodeIgniter using the trim() function provided by PHP.
