Creating PHP array

Creating arrays in PHP

We will create an array and assign multiple values to this array like this

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

We can create an array with assigned Key and values like this.

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

Creating array by breaking string

We can create an array by breaking string. Let us try with some simple examples.

///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>"; 
}

Here we have used space as delimiter and creaed the array by breaking the string. The output of above code is here.

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

Now let us try another program. This is a keyword list, we will try to create array by breaking the string with coma as delimiter. Only changes to above code is shown here

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

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

Output is here

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

If you want to know how many keywords are present by using array_size then here is the code.

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

Output of this is here

Total Number of words = 5

Creating array by using range()

We can specify a range and step to create an array by using numbers or chars between the range.

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

Output

0 1 2 3 4 5 6 7 8 9 10
