PHP String

PHP Programming

PHP is used for text data type like Hello World!. Example :

<!DOCTYPE html>
<html>
        <head>
        <meta charset="UTF-8">
        <title>DEV</title>
    </head>
    <body>
        <?php
        $myString = "My String";
        var_dump($myString);
        echo "<br>";
        ?>
    </body>
</html>

But string in PHP has more function like get the length of a string, count the number of words in a string, reverse string, search for a specific text within a string, replace text within a string.

Get the Length of a String

This code is used strlen() code. Example :

<!DOCTYPE html>
<html>
        <head>
        <meta charset="UTF-8">
        <title>DEV</title>
    </head>
    <body>
        <?php
        echo strlen("Hello world!"); // the output is 12
        ?>
    </body>
</html>

The output of code above is 12.

Count the Number of Words in a String

This code is used str_word_count() code. Example :

<!DOCTYPE html>
<html>
        <head>
        <meta charset="UTF-8">
        <title>DEV</title>
    </head>
    <body>
        <?php
        echo str_word_count("Hello world!"); // the output is 2
        ?>
    </body>
</html>

The output of code above is 2.

Reverse String

This code is used strrev() code. Example :

<!DOCTYPE html>
<html>
        <head>
        <meta charset="UTF-8">
        <title>DEV</title>
    </head>
    <body>
        <?php
        echo strrev("Hello world!"); // the output is !dlrow olleH
        ?>
    </body>
</html>

The output of code above is !dlrow olleH.

Search for a Specific Text Within a String

This code is used strpos() code. Example :

<!DOCTYPE html>
<html>
        <head>
        <meta charset="UTF-8">
        <title>DEV</title>
    </head>
    <body>
        <?php
        echo strpos("Hello world!", "Hello"); // the output is 6
        ?>
    </body>
</html>

The output of code above is 6.

Replace Text Within a String

This code is used str_replace() code. Example :

<!DOCTYPE html>
<html>
        <head>
        <meta charset="UTF-8">
        <title>DEV</title>
    </head>
    <body>
        <?php
        echo str_replace("world", "Bro", "Hello world!"); // the output is Hello Bro!
        ?>
    </body>
</html>

The output of code above is Hello Bro!.
