#PHP TRIM STRING LENGTH CODE#
The output for this code snippet would be the following: e freelance developeĪs you can see the “hir” from “Hire” and the “r” from “developer” were removed. Now let’s look at a case where we pass a second argument.

This parameter specifies the character that needs to be removed from the string. This is the string or the variable containing the string from which you want to remove whitespaces or characters.
Post that we look at a code snippet using the trim() function. In this section, we look at the various syntax, parameters, and return values used in the trim() function. trim () - Removes whitespace or other predefined characters from both sides of a string. Related functions: ltrim () - Removes whitespace or other predefined characters from the left side of a string.
