"what you should do first is to put the table in a string"

Sorry, but isn't that already the case in the $homepage variable created by the file_get_contents() function?

$homepage = file_get_contents('http://www.example.com/');

for($i=0;$i<count .="$homepage[i];">Hello efficiency... It recreates a value through concatenation as many times as there are lines in the source code of the page. Doesn't that bother you? 

or($i=0;$i<count .="str_replace(&quot;\n&quot;," str_replace="" />", "", str_replace("
", "", str_replace("
", "", $homepage[$i]))));

Processing HTML source code like this is a heresy.
Is there not a function in PHP that allows displaying special characters present in a string?
You need to have a precise view of what is in a string if you want to work on it.

I would like to point out that the HTML codes of pages are not always 100% compliant with what they should be
Sometimes what should fit on a single line is fragmented into two or even three lines. How are you going to handle those cases?

To handle strings, and particularly HTML source codes, you have to use regular expressions directly on the strings, not go through insane string transformations and arrays.

Or use an HTML parser that has been designed to navigate all the traps posed by the potential non-compliance of HTML codes.</count></pre>
