Question

I currently have this function to search and replace in a text file.

// Input
$ect = array('Visssa', 'Lisssa', 'her');

// Placeholders in the file
$put =  array('lname', 'fname', 'hisher');


// Replace the placeholders
$oput = str_replace($put, $ct, 'tmpfile.txt');

This is not the full program but the idea is replace the values found in tmpfile.txt with the ones found in the $etc array. And it works flawlessly.

But, what I need to do is get all passed vars (get/post) and then make the arrays so that the var is the value to replace and the value is the value to replace it with.

So, if I sent the url http://xyz.com/?lname=tom&ogre=yes

All instances of lname in the file would be replaces with tom and all instances of ogre would be replaced with yes.

So somehow it just gets any/all variables passed in get/post and then the arrays showed above would cause the var to be replaced by the value in the file.

Do this:

    $etc = array_keys($_GET);
    array_walk($etc,"addBraces");
    $put = array_values($_GET);
    $oput = str_replace($etc, $put, 'tmpfile.txt'); 

    function addBraces(&$item)
    {
        $item = "{".$item."}";
    }

And of course, all the regular “always santize/escape your data” etc…
