# apc_delete_file

(PECL apc >= 3.1.1)

apc_delete_file — Deletes files from the opcode cache

### 说明

apc_delete_file ( mixed `$keys` ) : mixed

Deletes the given files from the opcode cache.

### 参数

`keys`

  The files to be deleted. Accepts a string, array of strings, or an APCIterator object.

### 返回值

成功时返回 `TRUE`， 或者在失败时返回 `FALSE`。 Or if `keys` is an array, then an empty array is returned on success, or an array of failed files is returned.

### 范例

Example #1 apc_delete_file() example

    <?php
    $filename = 'file.php';

    if (apc_compile_file($filename)) {

        if (apc_delete_file($filename)) {
            echo "Successfully deleted file $filename from APC cache.", PHP_EOL;
        }
    }

    if (apc_compile_file($filename)) {

        if ($good = apc_delete_file(array($filename, 'donotexist.php'))) {
            var_dump($good);
        }
    }

    $bad = apc_delete_file('donotexist.php');
    var_dump($bad);
    ?>

以上例程的输出类似于：

    Successfully deleted file file.php from APC cache.
    [Mon May 24 09:30:33 2010] [apc-warning] Could not stat file donotexist.php, unable to delete from cache. in /tmp/test.php on line 13.
    array(1) {
      [0]=>
      string(14) "donotexist.php"
    }
    [Mon May 24 09:30:33 2010] [apc-warning] Could not stat file donotexist.php, unable to delete from cache. in /tmp/test.php on line 18.
