String Operations

http://webhostingneeds.com/tmp_fp/mistakes.jpg

On Day 2, we learned how to use strings. Today we will learn more string related operations.

PHP provide various functions that help us to work with strings.

Finding Length of a String

strlen() function is used to find length of a string.

strlen.php

PHP Code:

---

<?php

$companyName = 'FlashWebHost.com';

echo strlen($companyName);

---

Convert Text to Upper Case.

PHP Provide strtoupper() function to convert strings (text) to upper case.

strtoupper.php

PHP Code:

---

<?php

$companyName = 'FlashWebHost.com';

echo strtoupper($companyName);

---

Convert Text to Lower Case.

strtolower() function can convert text to lower case.

strtolower.php

PHP Code:

---

<?php

$companyName = 'FlashWebHost.com';

echo strtolower($companyName);

---

Convert First Letter of Words to Upper Case

ucwords() convert first letter of each word to upper case.

ucwords.php

PHP Code:

---

<?php

$myCar = 'I have a red car';

$myCar = ucwords($myCar);

echo $myCar;

echo '<br>';

$myBus = 'I HAVE A RED BUS';

$myBus = ucwords($myBus);

echo $myBus;

---

Replacing Text

str_replace() function in allow you to replace text in a string.

str_replace.php

PHP Code:

---

<?php

$myCar = 'I have a red car';

$myCar = str_replace('red', 'white', $myCar);

echo $myCar;

---

Here str_replace() find text 'red' and replace it with 'white' inside variable $myCar.

Nice, you can directly pass string to strlen() function.

Code:

---

<?php

$length = strlen ('Beautiful World');

echo $length;

---

Here we store the number rrturned by strlen() function to variable $length. Then echo it.

http://php.flashwebhost.com/sherly/mother.php

Code:

---

<?php
$str = 'Mother is the name for God in the lips and hearts of little children';
$str = strtoupper($str);
echo $str; // MOTHER IS THE NAME FOR GOD IN THE LIPS AND HEARTS OF LITTLE CHILDREN

That is fixed, no ucfirst() this time, lets keep it simple, we don't need to learn everything. We can learn more functions as required.

In this code ?> is not necessary. ?> is used only when php is used in between other language codes.

DAY 3 - strlen()

http://php.flashwebhost.com/vineesh/day3/strlen.php

Code

Code:

---

<?php

$sentenceOne = 'Hello, I am Vineesh Mohan';
$sentenceTwo = 'I am working in FlashWebHost.com';
$sentenceThree = 'FlashWebHost.com provides Domain Registration, Hosting And Web Design Services';
