在PHP中有没有一个函数代表一个空格?
像ACCESS似的SPACE(10)代表10空格?

str_repeat
(PHP 4 )

str_repeat -- Repeat a string
Description
string str_repeat ( string input, int multiplier)


Returns input_str repeated multiplier times. multiplier has to be greater than or equal to 0. If the multiplier is set to 0, the function will return an empty string.

Example 1. str_repeat() example

<?php
echo str_repeat("-=", 10);
?>



This will output "-=-=-=-=-=-=-=-=-=-=".

See also for, str_pad(), and substr_count().

str_pad
(PHP 4 >= 4.0.1)

str_pad -- Pad a string to a certain length with another string
Description
string str_pad ( string input, int pad_length [, string pad_string [, int pad_type]])


This functions returns the input string padded on the left, the right, or both sides to the specified padding length. If the optional argument pad_string is not supplied, the input is padded with spaces, otherwise it is padded with characters from pad_string up to the limit.

Optional argument pad_type can be STR_PAD_RIGHT, STR_PAD_LEFT, or STR_PAD_BOTH. If pad_type is not specified it is assumed to be STR_PAD_RIGHT.

If the value of pad_length is negative or less than the length of the input string, no padding takes place.

Example 1. str_pad() example

<?php
$input = "Alien";
print str_pad($input, 10); // produces "Alien "
print str_pad($input, 10, "-=", STR_PAD_LEFT); // produces "-=-=-Alien"
print str_pad($input, 10, "_", STR_PAD_BOTH); // produces "__Alien___"
?>
