Creating arrays in PHP

1. Indexed or Numeric Array
2. Associative Array
3. Multidimensional Array

Indexed array

$my_data = array('mydata1','mydata2','mydata3', 'Mydata');

echo $my_data[2] // mydata3

• Creating and displaying Array

Associative Array

$var=array(013=>"RKt",005=>"Bin",007=>"Alen");// Array key with value
$ar=array("FName"=>"John","Address"=>"Streen No 11 ",
          "City"=>"Rain Town","Country"=>"USA");

echo $var[007]; // Alen
echo "<br>";
echo $ar["City"]; // Rain Town

Creating array by breaking string

///Storing the sample paragraph in a variable /////
$string='plus2net provides easy tutorials for learning web programming';

$new_array=explode(" ",$string); // create an array by breaking string

// Let us display all elements of the array. ///
while (list ($key, $val) = each ($new_array)) { 
echo "$key -> $val <br>"; 
}

0 -> plus2net 
1 -> provides 
2 -> easy 
3 -> tutorials 
4 -> for 
5 -> learning 
6 -> web 
7 -> programming

$string='scripts , languages, programs, forms, database';

$new_array=explode(",",$string);

0 -> scripts 
1 -> languages 
2 -> programs 
3 -> forms 
4 -> database 

echo "Total Number of words = ".sizeof($new_array);

Total Number of words = 5

Creating array by using range()

$my_array=range(0,10); // create an array
foreach ($my_array as $element) {
    echo $element . "  ";
}

0 1 2 3 4 5 6 7 8 9 10
