php - 我想在字符串末尾连接一个单引号

Question

我想在字符串的末尾加上一个单引号我怎么能在 php 中做这件事？

    $file = $this->form->getValue('doc');
    $filename = $file->getOriginalName();
    $file_name=$fn.'_'.md5($fiename);
    $extension = $file->getExtension($file->getOriginalExtension());

Answer 1

像这样试试

$file = $this->form->getValue('doc');
$filename = $file->getOriginalName();
$file_name=$fn.'_'.md5($filename); //There is no $fiename, so i changed it to $filename
$file_name=$file_name."'";//Concatenating here.
$extension = $file->getExtension($file->getOriginalExtension());

Answer 2

试试这个：

$file_name=$fn.'_'.md5($fiename).",";

在 php.中用于连接。
