Question

我有如下的数组

Array
(
    [0] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR04A-94527.jpg
    [1] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR05A-95528.jpg
    [2] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR06A-961000001.jpg
    [3] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR06A-96529.jpg
    [4] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR07A-971000002.jpg
    [5] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR07A-97530.jpg
    [6] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR08A-981000003.jpg
    [7] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR08A-98531.jpg
    [8] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR09A-991000004.jpg
    [9] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR09A-99532.jpg
    [10] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR09A-99533.jpg
    [11] => C:\wamp\www\sthub\application\controllers/../../download/qr/SyR09A-99534.jpg
    [12] => C:\wamp\www\sthub\application\controllers/../../download/qr/Syno53.jpg
    [13] => C:\wamp\www\sthub\application\controllers/../../download/qr/Syno54.jpg
    [14] => C:\wamp\www\sthub\application\controllers/../../download/qr/Syno55.jpg
    [15] => C:\wamp\www\sthub\application\controllers/../../download/qr/Syno56.jpg
    [16] => C:\wamp\www\sthub\application\controllers/../../download/qr/Syno57.jpg
)

我希望在最后一次斜线之后和之前获得价值，如SyR04A-94527，SyR05A-95528等。

Answer 1

你正在尝试解析文件名，PHP已经有很多内置函数来做到这一点。没有必要使用-ms-grid-column或正则表达式等操作字符串本身：

auto

Answer 2

使用Regx：

<?php
$a = [
    'C:\wamp\www\sthub\application\controllers/../../download/qr/SyR04A-94527.jpg',
    'C:\wamp\www\sthub\application\controllers/../../download/qr/SyR05A-95528.jpg'
];

foreach( $a AS $path ){
    if( preg_match('/\/([^\/]+)\.[a-z]+$/i', $path, $match))
        print_r($match[1]."\n");
}

输出：

 SyR04A-94527
 SyR05A-95528

进行测试

我打算使用pathinfo，但我的沙盒网站已将其禁用，而且我懒得打开我的服务器。但它会是这样的：

$a = [
   'C:\wamp\www\sthub\application\controllers/../../download/qr/SyR04A-94527.jpg',
   'C:\wamp\www\sthub\application\controllers/../../download/qr/SyR05A-95528.jpg'
];

foreach( $a AS $path )
    echo pathinfo ($path, PATHINFO_FILENAME)."\n";

干杯！

获得Last斜杠的价值。在PHP中
