如何使用数组中的元素在PHP中打印文本文件[重复]

I am a beginner with PHP code and I'm trying to figure out how to use a variable inside a file_get_contents.

I have an array of names that are associated with textfiles in a certain folder. I am trying to use the name in the array to print out the text file.

echo '<p>';  
echo nl2br(file_get_contents( "Files/"+$names[1]+".txt"));
echo '</p>';

</div>

In order to concatenate php variables with string, you need to use dot operator. In your case, the second line of code should be:

echo nl2br(file_get_contents( "Files/" . $names[1] . ".txt"));
