• PHP - Trimming Strings

  Posted on April 13th, 2009 admin No comments

  The trimming string functions:

  In a string you can have excess whitespace you don’t need but is very useful if you want to store this string in a file or database.

  The trim() function will remove any whitespace from the beginning or end of string for example if you had the string “   celebrity   ” the resulting string will be “celebrity” as all the whitespace is removed from the start and end.

  There are two other trimming functions and these are:

  ltrim() and rtrim()

  These functions do the same thing as the ‘trim()’ function but instead the first one removes whitespace from the left hand side and the other one removes whitespace from the right hand side.

  The main purpose of trimming is to have cleaner input from your visitors, for  example if they were to accidently include a space before they input their name on a form.
