Remove Code

[Lol5916]

Ok so I have something on my index.php like:

<?php
$filename = "install.php";
if (file_exists($filename)) {
echo "Site cannot be executed until the site is installed. <br> <a href="install.php">Click here to install site</a>";
die;
} else {
REMOVETHISCODE
?>

If else is ran how do I get it to remove every line above it until it's at the top of the file, OR how do I get it to remove that php?

Hey man, if you have DIE function - PHP stops executing rest of the code

[crashmaster]

should be die();

Ok thanks, but that's not the question and I would have figured it out eventually xD

should be die();

 

Actually if you're not doing anything within the parenthesis they are option so die; is fine...

 

@ Lol5916

 

So once your code is installed you go to index.php and do;

 

<?php
$filename = "install.php";
if (file_exists($filename)) {
echo "Site cannot be executed until the site is installed. <br> <a href="install.php">Click here to install site</a>";
die;
} else {
REMOVETHISCODE

 

And the first time that runs successfully you want to delete those lines so it never does the check again?

Yes, that is correct.

My heads telling me the quick answer is no, because you'll be executing a script on the file that the script is running from. So as it start to write the file (without your lines) it will basically kill itself and leave you with a blank index.php

 

Seeing as the insignificance of the few lines of code why not just leave them in....

 

<?php
if (file_exists("install.php")) { echo "Site cannot be executed until the site is installed. <br> <a href="install.php">Click here to install site</a>"; die; }

REMOVETHISCODE

 

You can just make it the first line of the page

Actually, if you really want to get rid of it I think I've found away.

 

The first time index.php runs successfully you push it to another page

 

header('Location: sort_index.php');

 

then sort_index.php write the index file and deletes itself.

 

though i still dont think its necessary

What if I do something like include the install.php, I just don't know how I would stop it from making an error after it was installed.

echo "Site cannot be executed until the site is installed. <br> <a href="install.php">Click here to install site</a>";

 

 

 

Is a syntax error....

 

 

echo "Site cannot be executed until the site is installed. <br> <a href=\"install.php\">Click here to install site</a>";

Well if you're making this for users I'd recommend on completion tell them they should delete it. If it is called have a check at the top to see if it's already installed.
