LTRIM

Strip whitespace (or other characters) from the beginning of a string

SYNTAX

ltrim ( string $str [, string $character_mask = " \t\n\r\0\x0B" ] ) : string

PARAMETERS

str

The input string.

character_mask

You can also specify the characters you want to strip, by means of the character_mask parameter. Simply list all characters that you want to be stripped. With .. you can specify a range of characters. Without the character_mask parameter, ltrim() will strip these characters:

"\0" ASCII 0 (0x00) NUL-byte
"\t" ASCII 9 (0x09) horizontal tab
"\n" ASCII 10 (0x0A) new line (line feed)
"\v" ASCII 11 (0x0B) vertical tab
"\r" ASCII 13 (0x0D) carriage return
" " ASCII 32 (0x20) ordinary space

RETURN

Returns a string with whitespace stripped from the beginning of str.
