ltrim --
Strip whitespace (or other characters) from the beginning of a string
Syntax
string ltrim ( string str [, string charlist] )
Note:
The second parameter was added in PHP 4.1.0
This function returns a string with whitespace stripped from the
beginning of str.
Without the second parameter,
ltrim() will strip these characters:
" " (ASCII 32
(0x20)), an ordinary space.
"\t" (ASCII 9
(0x09)), a tab.
"\n" (ASCII 10
(0x0A)), a new line (line feed).
"\r" (ASCII 13
(0x0D)), a carriage return.
"\0" (ASCII 0
(0x00)), the NUL-byte.
"\x0B" (ASCII 11
(0x0B)), a vertical tab.
You can also specify the characters you want to strip, by means
of the charlist parameter.
Simply list all characters that you want to be stripped. With
.. you can specify a range of characters.

<?php
$text = "\t\tThese are a few words :) ... "; $trimmed = ltrim($text); // $trimmed = "These are a few words :) ... " $trimmed = ltrim($text, " \t."); // $trimmed = "These are a few words :) ... " $clean = ltrim($binary, "\x00..\x1F"); // trim the ASCII control characters at the beginning of $binary // (from 0 to 31 inclusive)
