php 如何遍历文件到一个数组中去？
请看下图描述：
class FileExtensionFinder extends FilterIterator {
protected $predicate, $path;
public function __construct($path, $predicate) {
$this->predicate = $predicate;
$this->path = $path;
$it = new RecursiveDirectoryIterator ( $path );
$flatIterator = new RecursiveIteratorIterator ( $it );
parent::__construct ( $flatIterator );
}
public function accept() {
$pathinfo = pathinfo ( $this->current () );
$extension = $pathinfo ['extension'];
return ($extension == $this->predicate);
}
}
$it = new FileExtensionFinder ( '.', 'css' );
print_r ( iterator_to_array ( $it, FALSE ) );
学习了楼上的写法.
PHP code:
<?php
class FileExtensionFinder extends FilterIterator {
protected $predicate, $path;
public function __construct($path, $predicate) {
$this->predicate = $predicate;
$this->path = $path;
$it = new RecursiveDirectoryIterator ( $path );
$flatIterator = new RecursiveIteratorIterator ( $it );
parent::__construct ( $flatIterator );
}
public function accept() {
$pathinfo = pathinfo ( $this->current () );
$extensio
