fnmatch

(PHP 4 >= 4.3.0, PHP 5)

fnmatchRepère un fichier à partir d'un masque de recherche

Description

bool fnmatch ( string $pattern , string $string [, int $flags ] )

Vérifie si la chaîne string va passer le masque Shell pattern .

Liste de paramètres

pattern

Le masque Shell.

string

La chaîne testée. Cette fonction est particulièrement utile pour les noms de fichier, mais peut également être utilisée sur des chaînes régulières.

L'utilisateur moyen de Shell peut être familier avec les masques Shell, ou tout au moins, leurs expressions les plus simples, comme '?' et '*'. De cette façon, utiliser fnmatch() au lieu de ereg() ou preg_match() pour des recherches peut être plus pratique pour les non-initiés.

flags

Voir la page man Unix sur fnmatch(3) pour les noms des drapeaux. (tant qu'ils ne sont pas documentés dans notre documentation).

Valeurs de retour

Retourne TRUE s'il y a des résultats, FALSE sinon.

Exemples

Exemple #1 Vérifier le nom d'une couleur avec un masque Shell

<?php
if (fnmatch("*gr[ae]y"$color)) {
  echo 
"des formes de gris ...";
}
?>

Notes

Avertissement

Actuellement, cette fonction n'est pas disponible pour Windows et les autres systèmes non-POSIX.

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).

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.
<?php
$pattern
= strtr(preg_quote($pattern, '#'), array('\*' => '.*', '\?' => '.', '\[' => '[', '\]' => ']'));
?>
And thanks for the functions, guys.

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:
<?php
define
('FNM_PATHNAME', 1);
define('FNM_PERIOD', 4);
define('FNM_NOESCAPE', 2);
// GNU extensions
define('FNM_FILE_NAME', FNM_PATHNAME);
define('FNM_LEADING_DIR', 8);
define('FNM_CASEFOLD', 16);
?>

I didn’t test any of these except casefold, which worked for me.

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

A revised better alternative for fnmatch on windows. It should work well on PHP >= 4.0.0

<?php
   
if (!function_exists('fnmatch')) {
        function
fnmatch($pattern, $string) {
            return @
preg_match(
               
'/^' . strtr(addcslashes($pattern, '/\\.+^$(){}=!<>|'),
                array(
'*' => '.*', '?' => '.?')) . '$/i', $string
           
);
        }
    }
?>

soywiz's function didnt seem to work for me, but this did.

<?php
if(!function_exists('fnmatch')) {

    function
fnmatch($pattern, $string) {
        return
preg_match("#^".strtr(preg_quote($pattern, '#'), array('\*' => '.*', '\?' => '.'))."$#i", $string);
    }
// end

} // end if
?>

A better "fnmatch" alternative for windows that converts a fnmatch pattern into a preg one. It should work on PHP >= 4.0.0

<?php
   
if (!function_exists('fnmatch')) {
        function
fnmatch($pattern, $string) {
            return @
preg_match('/^' . strtr(addcslashes($pattern, '\\.+^$(){}=!<>|'), array('*' => '.*', '?' => '.?')) . '$/i', $string);
        }
    }
?>

The last line of soywiz at gmail dot com windows replacement should be changed to:

   return preg_match('/' . $npattern . '$/i', $string);

otherwise, a pattern for *.xml will match file.xml~ or any else anything with the text *.xml in it, regardless of position.

A "fnmatch" alternative that converts the pattern, to a valid preg one and uses preg_match then. It will work on windows.

<?php
if (!function_exists('fnmatch')) {
function
fnmatch($pattern, $string) {
    for (
$op = 0, $npattern = '', $n = 0, $l = strlen($pattern); $n < $l; $n++) {
        switch (
$c = $pattern[$n]) {
            case
'\\':
               
$npattern .= '\\' . @$pattern[++$n];
            break;
            case
'.': case '+': case '^': case '$': case '(': case ')': case '{': case '}': case '=': case '!': case '<': case '>': case '|':
               
$npattern .= '\\' . $c;
            break;
            case
'?': case '*':
               
$npattern .= '.' . $c;
            break;
            case
'[': case ']': default:
               
$npattern .= $c;
                if (
$c == '[') {
                   
$op++;
                } else if (
$c == ']') {
                    if (
$op == 0) return false;
                   
$op--;
                }
            break;
        }
    }

    if (
$op != 0) return false;

    return
preg_match('/' . $npattern . '/i', $string);
}
}
?>

you couls also try this function that I wrote before I found fnmatch:

function WildToReg($str)
{
  $s = "";  
  for ($i = 0; $i < strlen($str); $i++)
  {
   $c = $str{$i};
   if ($c =='?')
    $s .= '.'; // any character
   else if ($c == '*')   
    $s .= '.*'; // 0 or more any characters   
   else if ($c == '[' || $c == ']')
    $s .= $c;  // one of characters within []
   else
    $s .= '\\' . $c;
  }
  $s = '^' . $s . '$';

  //trim redundant ^ or $
  //eg ^.*\.txt$ matches exactly the same as \.txt$
  if (substr($s,0,3) == "^.*")
   $s = substr($s,3);
  if (substr($s,-3,3) == ".*$")
   $s = substr($s,0,-3);
  return $s;
}

if (ereg(WildToReg("*.txt"), $fn))
  print "$fn is a text file";
else
  print "$fn is not a text file";
