TRIM(3) 1 TRIM(3)
trim - Strip whitespace (or other characters) from the beginning and end of a string
SYNOPSIS
string trim (string $str, [string $character_mask = " 0r B"])
DESCRIPTION
This function returns a string with whitespace stripped from the beginning and end of $str. Without the second parameter, trim(3) will
strip these characters:
o " " (ASCII
32 ( 0x20)), an ordinary space.
o " " (ASCII
9 ( 0x09)), a tab.
o "
" (ASCII
10 ( 0x0A)), a new line (line feed).
o "
" (ASCII
13 ( 0x0D)), a carriage return.
o " " (ASCII
0 ( 0x00)), the NUL-byte.
o "x0B" (ASCII
11 ( 0x0B)), a vertical tab.
PARAMETERS
o $str
- The string that will be trimmed.
o $character_mask
- Optionally, the stripped characters can also be specified using the $character_mask parameter. Simply list all characters that
you want to be stripped. With .. you can specify a range of characters.
RETURN VALUES
The trimmed string.
EXAMPLES
Example #1
Usage example of trim(3)
<?php
$text = " These are a few words :) ... ";
$binary = "x09Example stringx0A";
$hello = "Hello World";
var_dump($text, $binary, $hello);
print "
";
$trimmed = trim($text);
var_dump($trimmed);
$trimmed = trim($text, " .");
var_dump($trimmed);
$trimmed = trim($hello, "Hdle");
var_dump($trimmed);
$trimmed = trim($hello, 'HdWr');
var_dump($trimmed);
// trim the ASCII control characters at the beginning and end of $binary
// (from 0 to 31 inclusive)
$clean = trim($binary, "x00..x1F");
var_dump($clean);
?>
The above example will output:
string(32) " These are a few words :) ... "
string(16) " Example string
"
string(11) "Hello World"
string(28) "These are a few words :) ..."
string(24) "These are a few words :)"
string(5) "o Wor"
string(9) "ello Worl"
string(14) "Example string"
Example #2
Trimming array values with trim(3)
<?php
function trim_value(&$value)
{
$value = trim($value);
}
$fruit = array('apple','banana ', ' cranberry ');
var_dump($fruit);
array_walk($fruit, 'trim_value');
var_dump($fruit);
?>
The above example will output:
array(3) {
[0]=>
string(5) "apple"
[1]=>
string(7) "banana "
[2]=>
string(11) " cranberry "
}
array(3) {
[0]=>
string(5) "apple"
[1]=>
string(6) "banana"
[2]=>
string(9) "cranberry"
}
NOTES
Note
Possible gotcha: removing middle characters
Because trim(3) trims characters from the beginning and end of a string, it may be confusing when characters are (or are not)
removed from the middle. trim('abc', 'bad') removes both 'a' and 'b' because it trims 'a' thus moving 'b' to the beginning to also
be trimmed. So, this is why it "works" whereas trim('abc', 'b') seemingly does not.
