A great resource to have freelance programmers bid on your programming project. All project posting and bids take place on their forum. That is the only back side of this website - its working with a forum-like system. On the other hand the site has a good rating , completely free and concentrates on Programming. Not many sites do that, still it isn't a whole lot better than the average freelancing site.
This function will return the current time in seconds and microseconds. This is sometimes useful to track down the processing time of a script or other short lasting events.
function microtime_float()
{
list($usec, $sec) = explode(" ", microtime());
return ((float)$usec + (float)$sec);
}
An example usage could look like this:
$start = microtime_float();
// your code here
$took = round(microtime_float() - $start, 2);
echo "took $took seconds.";
This php function calculates the age in years for a given birthdate in the format YYYY-MM-DD.
function getAge($birthdate)
{
// get month, day, year
$tmp = split('-', $birthdate);
$month = (int)$tmp[1]; $day = (int) $tmp[2]; $year = (int) $tmp[0];
$current_day_of_year = 1 + date('z');
$user_day_of_year = 1 + date('z', mktime(1,1,1,$month, $day, $year));
$years = date('Y') - $year;
// we calculate based on birth day, if we haven't reached user's birthday yet,
// substract one year
if ($current_day_of_year < $user_day_of_year) {
$years--;
}
return $years;
}
This function allows it to hide the email address within a link so it is not this easy to be grabbed by spiders.
function mailto($address, $text)
{
$address_encode = '';
for ($x=0; $x < strlen($address); $x++) {
if(preg_match('!\w!',$address[$x])) {
$address_encode .= '%' . bin2hex($address[$x]);
} else {
$address_encode .= $address[$x];
}
}
$text_encode = '';
for ($x=0; $x < strlen($text); $x++) {
$text_encode .= '&#x' . bin2hex($text[$x]).';';
}
$mailto = "mailto:";
return ''.$text_encode.'';
}
echo mailto('my@mail.com','Mail me');
This little function cuts a string to a specified length while keeping the word boundaries under consideration.
function cuttext($text, $chars = 100)
{
if (strlen($text) > $chars) {
$newtext = substr($text, 0, $chars);
return preg_replace ("{\s+\S+$}", "...", $newtext);
} else {
return $text;
}
}
This little php class lets you create random characters of a given length.
class RandomGenerator
{
static $letters = array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o',
'p','q','r','s','t','u','v','w','x','y','z');
static $digits = array('1','2','3','4','5','6','7','8','9','0');
public function genKey($length = '128') {
$key = '';
$maxIndexLeters = count(self::$letters) - 1;
$maxIndexDigits = count(self::$digits) - 1;
for ($i= 0 ; $i < $length ; $i++) {
$makeDigit = (boolean) mt_rand(0,1);
if ($makeDigit) {
$index = mt_rand(0, $maxIndexDigits);
$key .= self::$digits[$index];
} else {
$index = mt_rand(0, $maxIndexLeters);
$makeUpperCase = (boolean) mt_rand(0,1);
if ($makeUpperCase) {
$key .= strtoupper(self::$letters[$index]);
} else {
$key .= self::$letters[$index];
}
}
}
return $key;
}
}
echo RandomGenerator::genKey();
