I have to show a page from my php script based on certain conditions. I have an if condition and am doing an "include" if the condition is satisfied.
if(condition here){
include "myFile.php?id='$someVar'";
}
Now the problem is the server has a file "myFile.php" but I want to make a call to this file with an argument (id) and the value of "id" will change with each call.
Can someone please tell me how to achieve this? Thanks.
file_get_contents() will get the content of a file, not execute it as a PHP script. If you want this piece of code to be executed, you need to either include it, or process it (through an HTTP request to Apache, for instance).
If you include this file, it'll be processed as PHP code, and of course, print your HTML tags (include* can take any kind of file).
If you need to work with its content before you print it, use ob_* functions to manipulate the PHP output buffer. See : http://www.php.net/manual/fr/ref.outcontrol.php
ob_start(); // Start output buffer capture.
include("yourtemplate.php"); // Include your template.
$output = ob_get_contents(); // This contains the output of yourtemplate.php
// Manipulate $output...
ob_end_clean(); // Clear the buffer.
echo $output; // Print everything.
By the way, such mechanism sounds heavy for a template engine. Basically, templates should not contain PHP code. If you want such behavior, have a look at Twig : http://twig.sensiolabs.org/
/ indicates an absolute path, meaning your script is looking in the root of the filesystem for a directory called interests.
Instead, try just removing that / at the start of your paths, or prepend $_SERVER['DOCUMENT_ROOT'] to them.
The answer seems to be NO.
NOTE: It should probably be implemented solely using PHP and a server directive to treat .shtml files as PHP.
There isn't a way to pass parameters to include or require.
However the code that is included joins the program flow at the point where you include it, so it will inherit any variables that are in scope. So for example if you set $myflag=true immediately before the include, your included code will be able to check what $myflag is set to.
That said, I wouldn't suggest using that technique. Far better for your include file to contain functions (or a class) rather than code that gets run straight off. If you've included a file containing functions then you can call your functions with whatever parameters you want at any point in your program. It's much more flexible, and generally a better programming technique.
Hope that helps.
Imagine the include as what it is: A copy & paste of the contents of the included PHP file which will then be interpreted. There is no scope change at all, so you can still access $someVar in the included file directly (even though you might consider a class based structure where you pass $someVar as a parameter or refer to a few global variables).
