Metóda - trim

(PHP 4, PHP 5, PHP 7)

The trim() function removes all so-called white spaces at the beginning and the end of a string. White spaces include spaces, tabs, ends of lines and other characters. These characters are: " ", "\t", "\n", "\r", "\0", "\x0B".

If we want to remove white spaces only from one side of the string, we use ltrim() and rtrim() functions (from the left and from the right).

Procedurálne

• function trim (string $str, string $character_mask = \t\n\r\0\x0B) : string
