The explode Function in PHP

PHP Code:

$rawPhoneNumber = "800-555-5555"; 

$phoneChunks = explode("-", $rawPhoneNumber);
echo "Raw Phone Number = $rawPhoneNumber <br />";
echo "First chunk = $phoneChunks[0]<br />";
echo "Second chunk = $phoneChunks[1]<br />";
echo "Third Chunk chunk = $phoneChunks[2]";

Display:

Raw Phone Number = 800-555-5555
First chunk = 800
Second chunk = 555
Third Chunk chunk = 5555 
 
 
 

explode Function - Setting a Limit

PHP Code:

$someWords = "Please don't blow me to pieces."; 

$wordChunks = explode(" ", $someWords);
for($i = 0; $i < count($wordChunks); $i++){
 echo "Piece $i = $wordChunks[$i] <br />";
}

$wordChunksLimited = explode(" ", $someWords, 4);
for($i = 0; $i < count($wordChunksLimited); $i++){
 echo "Limited Piece $i = $wordChunksLimited[$i] <br />";
}

Display:

Piece 0 = Please
Piece 1 = don't
Piece 2 = blow
Piece 3 = me
Piece 4 = to
Piece 5 = pieces.
Limited Piece 0 = Please
Limited Piece 1 = don't
Limited Piece 2 = blow

substring_index string function

substring_index string function

Substring_index function returns us a substring from the main string from a landmark which is given by delimiter. From the delimiter to left or right ( towards staring or ending ) of the string can be given by count. If count is positive then everything towards left from final delimiter ( from left ) is returned. If the count is negative then everything towards right from final delimiter is returned.

Here is the syntax

substring_index(string,"delimiter”,count )

We will apply this to our newsletter subscriber table where we stored email address of our subscribers. Here we will apply substring_index to separate domain part and userid part and maintain a list. Here is a sample of email address.

userid@domainname.com

Here is the query to get the

select email,substring_index(email,"@",-1) from newsletter_table

This will give output as

userid@aol.com aol.com
onemore@gmail.com gmail.com

Like this the full list can be displayed. We can use count and group by command to generate a query to which can tell us number of subscribers in each domain. Say how many have yahoo account, how many have gmail account etc….

SELECT count(substring_index(email,"@",-1) ) as no, email FROM `newsletter_table` group by substring_index(email,"@",-1) order by no desc

PHP Functions

The real power of PHP comes from its functions.
In PHP, there are more than 700 built-in functions.

PHP Built-in Functions

For a complete reference and examples of the built-in functions, please visit our PHP Reference.

PHP Functions

In this chapter we will show you how to create your own functions.
To keep the script from being executed when the page loads, you can put it into a function.
A function will be executed by a call to the function.
You may call a function from anywhere within a page.

Create a PHP Function

A function will be executed by a call to the function.

Syntax

function functionName()
{
code to be executed;
}
PHP function guidelines:
  • Give the function a name that reflects what the function does
  • The function name can start with a letter or underscore (not a number)

Example

A simple function that writes my name when it is called:
<html>
<body>

<?php
function writeName()
{
echo "Kai Jim Refsnes";
}

echo "My name is ";
writeName();
?>

</body>
</html>
Output:
My name is Kai Jim Refsnes

PHP Functions - Adding parameters

To add more functionality to a function, we can add parameters. A parameter is just like a variable.
Parameters are specified after the function name, inside the parentheses.

Example 1

The following example will write different first names, but equal last name:
<html>
<body>

<?php
function writeName($fname)
{
echo $fname . " Refsnes.<br>";
}

echo "My name is ";
writeName("Kai Jim");
echo "My sister's name is ";
writeName("Hege");
echo "My brother's name is ";
writeName("Stale");
?>

</body>
</html>
Output:
My name is Kai Jim Refsnes.
My sister's name is Hege Refsnes.
My brother's name is Stale Refsnes.

Example 2

The following function has two parameters:
<html>
<body>

<?php
function writeName($fname,$punctuation)
{
echo $fname . " Refsnes" . $punctuation . "<br>";
}

echo "My name is ";
writeName("Kai Jim",".");
echo "My sister's name is ";
writeName("Hege","!");
echo "My brother's name is ";
writeName("Ståle","?");
?>

</body>
</html>
Output:
My name is Kai Jim Refsnes.
My sister's name is Hege Refsnes!
My brother's name is Ståle Refsnes?

PHP Functions - Return values

To let a function return a value, use the return statement.

Example

<html>
<body>

<?php
function add($x,$y)
{
$total=$x+$y;
return $total;
}

echo "1 + 16 = " . add(1,16);
?>

</body>
</html>
Output:
1 + 16 = 17

PHP Function array_flip()

Syntax

array array_flip ( array $input );

Definition and Usage

array_flip() returns an array in flip order, i.e. keys from input become values and values from input become keys.
If a value has several occurrences, the latest key will be used as its values, and all others will be lost.

Paramters

ParameterDescription
inputThe array to be fliped

Return Values

Returns FALSE if it fails otherwise fliped array.

Example

Try out following example:
<?php
$array = array("a"=>1, "b"=>2, "c"=>3, "d"=>4, "e"=>5);

print_r(array_flip($array));
?>
This will produce following result:
Array ( [1] => a [2] => b [3] => c [4] => d [5] => e)

PHP Function array_filter()

Syntax

array array_filter ( array $input [, callback $callback] );

Definition and Usage

Iterates over each value in the input array passing them to the callback function. If the callback function returns true, the current value from input is returned into the result array. Array keys are preserved.

Paramters

ParameterDescription
inputThe array to iterate over
callbackThe callback function to use
If no callback is supplied, all entries of input equal to FALSE will be removed.

Return Values

Returns the filtered array.

Example

Try out following example:
<?php
function odd($var)
{
    return($var & 1);
}

function even($var)
{
    return(!($var & 1));
}

$array1 = array("a"=>1, "b"=>2, "c"=>3, "d"=>4, "e"=>5);
$array2 = array(6, 7, 8, 9, 10, 11, 12);

echo "Odd :\n";
print_r(array_filter($array1, "odd"));
echo "Even:\n";
print_r(array_filter($array2, "even"));
?>
This will produce following result:
Odd :

PHP Function array_diff_ukey()

Syntax

array_diff_ukey ( $array1, $array2 [, $array3...,callback $key_compare_func] );

Definition and Usage

Compares the keys from array1 against the keys from array2 and returns the difference. This function is like array_diff() except the comparison is done on the keys instead of the values.
Unlike array_diff_key() an user supplied callback function is used for the indices comparision, not internal function.

Paramters

ParameterDescription
array1Required. The first array is the array that the others will be compared with.
array2Required. An array to be compared with the first array
array3Optional. An array to be compared with the first array
key_compare_funcRequired. callback function to use. The callback function must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

Return Values

Returns an array containing all the entries from array1 that are not present in any of the other arrays.

Example

Try out following example:
<?php
function key_compare_func($v1,$v2) 
{
if ($v1===$v2)
 {
 return 0;
 }
if ($v1>v2)
 {
 return 1;
 }
else
 {
 return -1;
 }
}
$array1 = array(0=>"banana", 1=>"orange", 2=>"grapes");
$array2 = array(3=>"apple",1=>"apricot", 5=>"mango");
print_r(array_diff_ukey($array1,$array2,"key_compare_func"));
?>
This will produce following result:
Array ( [0]=>banana [2]=>grapes )

PHP Function array_diff_uassoc()

Syntax

array_diff_uassoc ( $array1, $array2 [, $array3..., callback $key_compare_func] );

Definition and Usage

Compares array1 against array2 and returns the difference. Unlike array_diff() the array keys are used in the comparision.
Unlike array_diff_assoc() an user supplied callback function is used for the indices comparision, not internal function.

Paramters

ParameterDescription
array1Required. The array to compare from
array2Required. An array to be compared with the first array
array3Optional. An array to be compared with the first array
key_compare_funcRequired. callback function to use. The callback function must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second.

Return Values

Returns an array containing all the entries from array1 that are not present in any of the other arrays.

Example

Try out following example:
<?php
function key_compare_func($a, $b)
{
    if ($a === $b) {
        return 0;
    }
    return ($a > $b)? 1:-1;
}
$array1 = array("a" => "green", "b" => "brown", 
                                    "c" => "blue", "red");
$array2 = array("a" => "green", "yellow", "red");
$result = array_diff_uassoc($array1, $array2, "key_compare_func");
print_r($result);

?>
This will produce following result:
