help with installation - creation file

[gabrielkolbe]

Hi, I have a website, which I want to install on 'clients' servers..the website run on PHP, MySQL. Firstly I want a page to check if PHP is installed, then MySQL, then smtp, gd, curl. Can I use the phpinfo(), ? I tried to use phpinfo() place it in a string and search the strings for certain values, but it does not seem to work.. does anyone have any ideas, or better any scripts I can just edit?

I would be greatful.

You can try function_exists() to test for certain functions, or you can just pass the phpinfo() data to grep or something.

Hi, thanks for that. I can use function_exist, but also need to verify the data in the phpinfo() page.. i don't understand 'pass the phpinfo() data to grep or something.' please explain. I probably need to get phpinfo() into a string..??

[DarkWater]

Yeah.

 

<?php
ob_start();
phpinfo();
$phpinfo = ob_get_clean();

 

From that point, you can just use a regex or something, or grep.  Whatever you want.

function_exists is by far the cleanest way to do this.

Indeed it is.  xD

[gabrielkolbe]

yes, I agree. But how do you check if the php dependencies are available (like smtp, gd, curl) with function_exist() ?

[DarkWater]

Use a function from that library?

 

if (function_exists('curl_init')) {

  //curl good

}

if (function_exists('imagecreatetruecolor')) {

  //gd good

}

 

And what's a function in the SMTP library? o-O

You will also have to check if the function is disabled.

 

function is_disabled($function) {
  $disabled_functions=explode(',',ini_get('disable_functions'));
  return in_array($function, $disabled_functions);
}

 

is_callable may do this for you, if you have a later version of PHP
