fnmatch()

(PHP 4 >= 4.3.0, PHP 5, PHP 7)

用模式匹配文件名

说明

fnmatch()检查传入的$string是否匹配给出的 shell 统配符$pattern。

参数

shell 统配符。

要检查的字符串。此函数对于文件名尤其有用，但也可以用于普通的字符串。

普通用户可能习惯于 shell 模式或者至少其中最简单的形式'?'和'*'通配符，因此使用fnmatch()来代替preg_match()来进行前端搜索表达式输入对于非程序员用户更加方便。

The value of$flagscan be any combination of the following flags, joined with thebinary OR (|) operator.

返回值

匹配则返回TRUE，否则返回FALSE。

范例

注释

目前该函数无法在 Windows 或其它非 POSIX 兼容的系统上使用。

• printf() 输出格式化字符串
• sprintf()Return a formatted string

An addition to my previous note: My statement regarding the FNM_* constants was wrong. They are available on POSIX-compliant systems (in other words, if fnmatch() is defined).

Here's a definitive solution, which supports negative character classes and the four documented flags. 

About the windows compat functions below:
I needed fnmatch for a application that had to work on Windows, took a look here and tested both. Jk's works for me, soywiz didn't (on WinXPSP2, PHP 5.2.3).
The only difference between them is addcslashes (soywiz) instead of preg_quote (jk). They _should_ both work, but for some reason soywiz's didn't for me. So YMMV.
However, to make JK's fnmatch() work with the example in the documentation, you also have to strtr the [ and ] in $pattern.

And thanks for the functions, guys.

soywiz's function still doesn't seem to work -- at least not with PHP 5.2.3 on Windows -- but jk's does.

you couls also try this function that I wrote before I found fnmatch:
function WildToReg($str)
{
 $s = "";  
 for ($i = 0; $i 
Possible flags (scratched out of fnmatch.h):
...::...
FNM_PATHNAME:
> Slash in $string only matches slash in $pattern.
FNM_PERIOD:
> Leading period in $string must be exactly matched by period in $pattern.
FNM_NOESCAPE:
> Disable backslash escaping.
FNM_NOSYS:
> Obsolescent.
FNM_FILE_NAME:
> Alias of FNM_PATHNAME.
FNM_LEADING_DIR:
> From fnmatch.h: /* Ignore `/...' after a match. */
FNM_CASEFOLD:
> Caseless match.
Since they’re appearing in file.c, but are not available in PHP, we’ll have to define them ourselves:

I didn’t test any of these except casefold, which worked for me.
fnmatch is not 100% reliable. Bug 14185 is still open and may or may not have been patched.
In certain wildcard circumstance fnmatch("*needle*", $haystack, match) returns false intermittantly
However stripos or preg returns a "find".
