Hello. Here, for example, there is a file with the contents - for example, "Test" and I connect it through require and how can I get this text (Test) to a variable?

  • NO! Because require (and everything like that) does not read the contents, much less RETURNS IT! - Salivan

It looks like nailing a microscope , which would be worth plugging in scripts. In addition, we must remember that require() will stop execution if there is no file.

Maybe better to look at file_get_contents() ?


  • Something about optimization (search by the words file_get_contents ).
  • Tests I spend too lazy - try it yourself.
  • file_get_contents () server loads heavily. I have already tried - they said that you live in the 20th century. - n1k
  • mmmmm .... exactly if the file connection is pushed to the buffering, and then everything comes out ?? ob_start (); include './test'; $ var = ob_get_contents (); ob_end_clean (); - n1k
  • doesn’t look very believable - I can’t say anything - xEdelweiss

Do not complicate the life of a file_get_contents or a buffer; you can make everything easier - drive the contents of the included file into return, when connecting it in another script, return it to a variable - example:


 <?php $var = 'PHP'; return $var; ?> 


 <?php $foo = include 'return.php'; echo $foo; // выведет 'PHP' ?> 

I hope that is what was meant

  • example taken from php.net - zippp
  • no, not that. I will have only html code in this file and I need to drive it into a variable - n1k
  • html code is text that can be represented as a string, which in turn can be a variable value, i.e. in the example above, instead of $ var = 'PHP', $ var = '<title> Start Page Title </ title>'; and you will return html if for some reason you don’t like it, use file_get_contents () - zippp

Do you really want this?

 ob_start(); include 'file.html'; $html = ob_get_clean(); 

Without testing, I’m ready to argue that when compared, the aforementioned @xEdelweiss file_get_contents will be faster.

Upd. And here is the comparison data ! The second answer. From fast to brake:

  1. file_get_contents ()
  2. readfile ()
  3. include
  • Thanks a lot. It’s just that some educated people tell me that something is loading the server and I go here and as a result it turns out that it does not load anything even the other way around - n1k
  • Why go from one "educated" people to others? Checking yourself is not so difficult:) @Deert, If you are given an exhaustive answer, mark it as correct (click on the check mark next to the selected answer). - Sergiks
  • advise a program with which you can find out the speed of the function (script) - n1k
  • In the answer, the reference "data comparison" is clickable. There in the second answer are code samples. In PHP, there is a micro-time function () that returns the time with an accuracy of 1/1000 of a second. Remember it before starting the cycle of 100,000 file reads in one of the ways, and compare it with the time measured immediately after. - Sergiks

Use the template engine. It can also return the template code to the variable.
