The Snippets Thread

[Arthur]

When I saw this thread, I thought "Oh! I'll post my hex color code generator!", but obviously that would be pointless, as there already is one. So I'll post my snippet to delete all files in a directory (useful if you want to have a temp folder and it gets full of non-deleted useless files.)

PHP Code:

function empty_folder($folder){
    $files = glob("$folder/*");
    for ($i = 0; $i < count($files); $i++){
        unlink($files[$i]);
    }
} 


Function to highlight a string where $str is the string to be highlighted, $bg is whether it's the background or the text that's highlighted, and $color is what color to highlight it:

PHP Code:

function highlight($str, $bg=true, $color=false){
    $type = "";
    if (!$color){
        $color = "#8B8B00";
    }
    if ($bg){
        $type = "background-";
    }
    return "<span style='".$type."color:$color;'>".$str."</span>";
}
