 Foreach (array_expression as $value){

statement;

}

Foreach (array_expression as $key => $value){

statement;

}

for example

<?php

$arr = array(2,3,4,5) ;

foreach($arr as &$value){

$value = $value * 2;

}

//$arr now is array(4,6,8,10)

unset($value);//break the reference with the last element

//warning Reference of a $value and the last array element remain even after the foreach loop.It is recommended to destroy it by unset().

?>

<?php

$arr = array(”apply “,”orange”,”banana”);

reset($arr); //Set the internal pointer of an array to its first element

foreach($arr as $key => $value){

echo “Key:$key;Value:$value<br />\n”;

}

?>

Hello,I wrote some code for getting sign by birthday.

You need to create two file.

 One is the file with the the code below and name it as sign_form.php

<form action=”get_sign.php” value=”">

year:<input name=”year” valut=”" type=”text” /> <br />

month:<input name=”month” valut=”" type=”text” /> <br />

day:<input name=”day” valut=”" type=”text” /> <br />

submit:<input submit=”submit” valut=”submit” type=”submit” /> <br />

</form>

then have another file with the code as below and save it as get_sign.php

         if((date(m) > $_POST[’month’]) || (date(m) == $_POST[’month’] && $_POST[’day’] <= date(d))){
         $age = date(Y) - $_POST[’year’] + 1;
         }else{
         $age = date(Y) - $_POST[’year’];
         }
         if(($_POST[’month’] == 1 && $_POST[’day’] >= 21) OR ($_POST[’month’] == 2 && 19 >= $_POST[’day’])){
            $sign = “Aquarius”;
         } elseif(($_POST[’month’] == 2 && 20 <= $_POST[’day’]) OR ($_POST[’month’] == 3 && $_POST[’day’] <= 20)){
            $sign = “Pisces”;
         } elseif(($_POST[’month’] == 3 && 21 <= $_POST[’day’]) OR ($_POST[’month’] == 4 && $_POST[’day’] <= 20)){
            $sign = “Aries”;
         } elseif(($_POST[’month’] == 4 && 21 <= $_POST[’day’]) OR ($_POST[’month’] == 5 && $_POST[’day’] <= 20)){
            $sign = “Taurus”;
         } elseif(($_POST[’month’] == 5 && 21 <= $_POST[’day’]) OR ($_POST[’month’] == 6 && $_POST[’day’] <= 21)){
            $sign = “Gemini”;
         } elseif(($_POST[’month’] == 6 && 22 <= $_POST[’day’]) OR ($_POST[’month’] == 7 && $_POST[’day’] <= 22)){
            $sign = “Cancer”;
         } elseif(($_POST[’month’] == 7 && 23 <= $_POST[’day’]) OR ($_POST[’month’] == 8 && $_POST[’day’] <= 22)){
            $sign = “Leo”;
         } elseif(($_POST[’month’] == 8 && 23 <= $_POST[’day’]) OR ($_POST[’month’] == 9 && $_POST[’day’] <= 22)){
            $sign = “Virgo”;
         } elseif(($_POST[’month’] == 9 && 23 <= $_POST[’day’]) OR ($_POST[’month’] == 10 && $_POST[’day’] <= 23)){
            $sign = “Libra”;
         } elseif(($_POST[’month’] == 10 && 24 <= $_POST[’day’]) OR ($_POST[’month’] == 11 && $_POST[’day’] <= 22)){
            $sign = “Scorpio”;
         } elseif(($_POST[’month’] == 11 && 23 <= $_POST[’day’]) OR ($_POST[’month’] == 12 && $_POST[’day’] <= 21)){
            $sign = “Sagittarius”;
         } elseif(($_POST[’month’] == 12 && 22 <= $_POST[’day’]) OR ($_POST[’month’] == 1 && $_POST[’day’] <= 20)){
            $sign = “Capricorn”;
         }
         echo $sign;

 Then we just visit the sign_form.php and input the birthday and click submit,we will get the sign according the birthday.
