php glob实现目录文件遍历与寻找与模式匹配的文件路径

例子 1
<?php
print_r(glob("*.txt"));
?>输出类似：

Array
(
[0] => target.txt
[1] => source.txt
[2] => test.txt
[3] => test2.txt
)例子 2
<?php
print_r(glob("*.*"));
?>输出类似：

Array
(
[0] => contacts.csv
[1] => default.php
[2] => target.txt
[3] => source.txt
[4] => tem1.tmp
[5] => test.htm
[6] => test.ini
[7] => test.php
[8] => test.txt
[9] => test2.txt
)

int extract ( array var_array [, int extract_type [, string prefix]] )

<?php
$a = 'Original';
$my_array = array("a" => "Cat","b" => "Dog", "c" => "Horse");

extract($my_array, EXTR_PREFIX_SAME, 'dup');

echo "$a = $a; $b = $b; $c = $c; $dup_a = $dup_a;";
?>

输出：

$a = Original; $b = Dog; $c = Horse; $dup_a = Cat;

<?php
parse_str("var1=liuhui&var2=parse_str");
echo $var1.$var2;
?>

<?php
parse_str("var1=liuhui&var2=parse_str",$array);
print_r($array);
?>

输出：Array ( [var1] => liuhui [var2] => parse_str )

<?php
parse_str("v ar1=liuhui&var 2=parse_str",$array);
print_r($array);
?>

输出：Array ( [v_ar1] => liuhui [var_2] => parse_str )

<?php
echo(strtotime("now"));
echo(strtotime("3 October 2005"));
echo(strtotime("+5 hours"));
echo(strtotime("+1 week"));
echo(strtotime("+1 week 3 days 7 hours 5 seconds"));
echo(strtotime("next Monday"));
echo(strtotime("last Sunday"));
?>输出：

1138614504
1128290400
1138632504
1139219304
1139503709
1139180400
1138489200

<?php
$str = 'Not Good';

// previous to PHP 5.1.0 you would compare with -1, instead of false
if (($timestamp = strtotime($str)) === false) {
    echo "The string ($str) is bogus";
} else {
    echo "$str == " . date('l dS of F Y h:i:s A', $timestamp);
}
?>

I just found out PHP thinks slashes in date-formats aren't very european:
(I guess this is not a bug, just the way it works. But correct me if I'm wrong.)
<?php

    $date = "06/10/2011 14:28"; // 6 october 2011 2:28 pm
    $otherDate = "06-10-2011 14:28"; // 6 october 2011 2:28 pm
   
    echo $stamp = strtotime($date) . "<br />"; // outputs 1307708880
    echo $otherStamp = strtotime($otherDate) . "<br />"; // outputs 1317904080
   
    echo date("d-m", $stamp); // outputs 10-06
    echo date("d-m", $otherStamp); // outputs 06-10

?>

setlocale(LC_ALL, 'zh_CN.UTF-8');
代码如下

// 上传的CSV文件,通常是用Excel编辑的GBK编码,
// 而源代码是UTF-8,需要进行转码处理
file_put_contents($new_file, iconv('GBK', 'UTF-8', file_get_contents($new_file)));

//ini_set('auto_detect_line_endings', true);
// 设置区域:简体中文,UTF-8编码
setlocale(LC_ALL, 'zh_CN.UTF-8');
// 打开CSV文件
$handle = fopen($new_file, 'r');
// 取出列头
$data_heads = fgetcsv($handle);
