include very easy

Special to reuse code in different folders
Code function:

function inc ($inc) {
$result = count(explode ("/",$_SERVER['PHP_SELF']))-2;
switch($result){
case '0':$inc='';break;
case '1':$inc='../';break;
case '2':$inc='../../';break;
case '3':$inc='../../../';break;
case '4':$inc='../../../../';break;
case '5':$inc='../../../../../';break;
                   }
return "$inc";
} 

Example:

$inc = inc(inc);
include_once($inc."/config.php");

I can't remember the topic where I put last time and date snippet but it is not quite exact in months and years, so this one is ok.
Replacement language is Serbian.

function TimeDate() {
$dan = date('l', time() + (2 * 60 * 60));
$dan = str_replace('Monday', 'Ponedeljak', $dan);
$dan = str_replace('Tuesday', 'Utorak', $dan);
$dan = str_replace('Wednesday', 'Sreda', $dan);
$dan = str_replace('Thursday', 'Četvrtak', $dan);
$dan = str_replace('Friday', 'Petak', $dan);
$dan = str_replace('Saturday', 'Subota', $dan);
$dan = str_replace('Sunday', 'Nedelja', $dan);

$datum = date('d.F Y.', time() + (2 * 60 * 60));
$datum = str_replace('January', 'Januar', $datum);
$datum = str_replace('February', 'Februar', $datum);
$datum = str_replace('March', 'Mart', $datum);
$datum = str_replace('April', 'April', $datum);
$datum = str_replace('May', 'Maj', $datum);
$datum = str_replace('June', 'Jun', $datum);
$datum = str_replace('July', 'Jul', $datum);
$datum = str_replace('August', 'Avgust', $datum);
$datum = str_replace('September', 'Septembar', $datum);
$datum = str_replace('October', 'Oktobar', $datum);
$datum = str_replace('November', 'Novembar', $datum);
$datum = str_replace('December', 'Decembar', $datum);

$sat = date('H:i', time() + (2 * 60 * 60));

echo '
<p>'.$dan.', '.$datum.' '.$sat.'</p>';
 } 

To adjust change value 2 to your needs in (2 * 60 * 60) , rest don't change.

Echo it:

echo TimeDate(); 

Looks like:

Petak, 28.Januar 2011. 20:03

Input link validation regardless is written http:// or not:

if (!preg_match('/^(http:\/\/)?[a-z0-9-\.]+\.[a-z]{2,4}$/iD', $var)) {
echo 'Invalid URL format!';
}

A useful little function to convert the symbols in the different inputs.

function ConvertSimbols($var, $ConvertQuotes = 0) {
if ($ConvertQuotes > 0) {
$var = htmlentities($var, ENT_NOQUOTES, 'UTF-8');
$var = str_replace(array('\"', "\'"), '', $var);
} else {
$var = htmlentities($var, ENT_QUOTES, 'UTF-8');
}
return $var;
} 

Usage with quotes for example message:

$message = ConvertSimbols($message); 

Usage without quotes for example link:

$link = ConvertSimbols($link, 1); 

Get user agent.

function user_agent() {
$Browser = isset($_SERVER['HTTP__AGENT']) ? $_SERVER['HTTP__AGENT'] : '';
$Browser = isset($_SERVER['HTTP_X_OPERAMINI_PHONE_UA']) ? $_SERVER['HTTP_X_OPERAMINI_PHONE_UA'] : $Browser;
$Browser = isset($_SERVER['HTTP_X_ORIGINAL__AGENT']) ? $_SERVER['HTTP_X_ORIGINAL__AGENT'] : $Browser;
$Browser = isset($_SERVER['HTTP_X_DEVICE__AGENT']) ? $_SERVER['HTTP_X_DEVICE__AGENT'] : $Browser;
$Browser = isset($_SERVER['HTTP_X_MOBILE_UA']) ? $_SERVER['HTTP_X_MOBILE_UA'] : $Browser;
$Browser = isset($_SERVER['HTTP_X_BOLT_PHONE_UA']) ? $_SERVER['HTTP_X_BOLT_PHONE_UA'] : $Browser;
$Agent = htmlentities($Browser, ENT_QUOTES, 'UTF-8');
if (empty($Agent)) {
$Agent = 'ProxyUA';
}
return $Agent;
}

From php.net comments:

function openFile($file, $mode, $input) {
    if ($mode == "READ") {
        if (file_exists($file)) {
            $handle = fopen($file, "r"); 
            $output = fread($handle, filesize($file));
            return $output; // output file text
        } else {
            return false; // failed.
        }
    } elseif ($mode == "WRITE") {
        $handle = fopen($file, "w");
        if (!fwrite($handle, $input)) {
            return false; // failed.
        } else {
            return true; //success.
        }
    } elseif ($mode == "READ/WRITE") {        
        if (file_exists($file) && isset($input)) {
            $handle = fopen($file, "r+");
            $read = fread($handle, filesize($file));
            $data = $read.$input;
            if (!fwrite($handle, $data)) {
                return false; // failed.
            } else {
                return true; // success.
            }
        } else {
            return false; // failed.
        }
    } else {
        return false; // failed.
    }
    fclose($handle); 
} 

Example calls are:

openFile("files/text.txt", "WRITE", "Hello World!");
echo openFile("files/text.txt", "READ"); // OUTPUT > Hello World!
openFile("files/text.txt", "READ/WRITE", "!!");
echo openFile("files/text.txt", "READ"); // OUTPUT > Hello World!!! 

And i edited it to be more usable for me with:

elseif ($mode == 'UPDATE') {
$marker = "\n";
if (is_writeable($file) && isset($input)) {
$handle = @fopen($file, 'a');
$data = $input.$marker;
if (!fwrite($handle, $data)) {
return false;
} else {
return true;
}
} else {
return false;
}
}

Can it used to open XML and parse it into php?

[arnage]

It can read and collect the content of xml file into a variable but as regards the elements of xml its needed to come up with some way to loop through it and call the specific elements.

If your script uses register globals on(and/or your server doesnt support it) and your to lazy use this function to help you.

function RegisterGlobalsOff()
{
   foreach ($_REQUEST AS $key=>$value)
   {
       if( ! isset(${$key}))
       {
           ${$key} = $value;
       }
   }
}

Code that cleans that ugly white lines caused by filezila and other:

<?php
$fileName = '';

if ($fileName == NULL)
{
    $fileName = isset($_GET['f']) ? $_GET['f'] : exit('<b>Usage: ?f=Filename.ext</b>');
}
$newLine = isset($_GET['nl']) ? TRUE : FALSE;

$f = file($fileName);

foreach ($f AS $k => $value)
{
    $f[$k] = str_replace(PHP_EOL, '', $f[$k]);
    if ($newLine)
    {
        $f[$k] = str_replace('{', PHP_EOL.'{'.PHP_EOL, $f[$k]);
        $f[$k] = str_replace('}', PHP_EOL.'}'.PHP_EOL, $f[$k]);
    }
    if ($f[$k] == NULL) 
        unset($f[$k]);
}
file_put_contents(mt_rand(10000, 99999).'-'.$fileName, implode(PHP_EOL, $f));

My simple number separator function:

<?php

    $numar = (string) $numar;
    $cifre = strlen($numar);
    
    $t = 1;
    $numar_formatat = '';
    for ($i = $cifre-1; $i>=0; $i--)
    {
        $numar_formatat = $numar[$i] . $numar_formatat;
        if ($t % $precizie == 0 && isset($numar[$i-1]))
        {
            $numar_formatat = $separator . $numar_formatat;
            $t = 1;
        }
        else
            $t++;
    }
    return $numar_formatat;
}
echo format_number(3000000); // Will output : 3.000.000
echo format_number(3000000, ','); // Will output : 3,000,000
// ARGS: format_number(int/string number, separator, precision);

//PS: if you pass the number like an int make sure that it not contains more than 14 digits or by string with unlimited digits

This validates case-insensitive e-mail addresses like:

name@mail.com
name.lastname@mail.com
name.lastname@some-mail.com

and so on.

function validemail($string) {
    if (preg_match('/^[a-z0-9\._-]+@[a-z0-9\.-]+\.[a-z]{2,4}$/iD', $string)) {
        return true;
    } else {
        return false;
    }
} 

This simple function can be used to set the hours time in the whole script at once or remotley where its called, can be used for mysql queries.

function thetime($toset = 0) {
    $thetime = time();
    $toset = (int) $toset;
    $set = $toset + 0;
    return $thetime + ($set * 60 * 60);
} 

This one is to display time and format stamp in desired format with time hour setting also:

function formatstamp($setformat = '', $stamp, $settime = 0) {
    return date($setformat, $stamp + ($settime * 60 * 60));
} 

Example with these two:

echo formatstamp('d.m.Y H:i', thetime(), $sethours).'<br/>';

Easy way to just cut the string or cut it with three dots like etc.

function cutout($string, $howmuch, $etc = false) {
    return mb_strlen($string, 'UTF-8') > $howmuch 
    ? mb_substr($string, 0, $howmuch, 'UTF-8').($etc !== false ? '...' : '') : $string;
} 

Example with ...

$string = 'Some too long string';
$string = cutout($string, 10, true);
echo $string; //Some too l...
