php擷取抓取檔案路徑
<?php
echo "<br>basename:";
echo basename("file://Users/financialbrain/Downloads/學生帳號密碼.pdf");
echo "<br>basename:";
echo dirname("file://Users/financialbrain/Downloads/學生帳號密碼.pdf");
?>
//結果
basename:學生帳號密碼.pdf
basename:file://Users/financialbrain/Downloads<?php
foreach (glob("*") as $key => $value) {
echo $value."<br>";
}
?>
//結果會抓取與這php檔案當前資料夾相同的檔案
//以下這些檔案都是在跟.php檔案同一個資料夾
//假設使用*.png就會抓到所有png檔案
