我想在字符串的末尾连接单引号

Question

我想在字符串的末尾连接单引号 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

试试这个

$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

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