In this article, we are going to learn how to check that a given string is starting or ending with a given specific string in PHP.
We require the use of XAMPP, Netbeans to run this code.
Input: "Geeks For Geeks" Starting with: "G" Output: "Geeks For Geeks Starts with String G"
In PHP version 8+, there are str_starts_with(), str_ends_with() functions which take two arguments one as, original string, the second as a string to be checked.
We will learn, how to check string starts/ends with a specific string.
Approach:
- We will create a basic HTML form to input two strings, the main string, and the string to be checked.
- We will validate the inputs using the str_starts_with(), str_ends_with() functions.
PHP code: Create a file “index.php” and write the following PHP code.
PHP
<!DOCTYPE html> <?php $msg = ""; error_reporting(0); if (isset($_POST['submit'])) { if ($_POST['stringSearchType'] == 0) { if ((str_starts_with($_POST['mainString'], strtoupper($_POST['checkString']))) || (str_starts_with($_POST['mainString'], strtolower($_POST['checkString']))) || (str_starts_with($_POST['mainString'], $_POST['checkString']))) { $msg = "The Given string [$_POST[mainString]] Starts with [$_POST[checkString]]"; } else { $msg = "The Given string [$_POST[mainString]] do not Starts with [$_POST[checkString]]"; } } else if ($_POST['stringSearchType']) { if ((str_ends_with($_POST['mainString'], strtoupper($_POST['checkString']))) || (str_ends_with($_POST['mainString'], strtolower($_POST['checkString']))) || (str_ends_with($_POST['mainString'], $_POST['checkString']))) { $msg = "The Given string [$_POST[mainString]] ends with [$_POST[checkString]]"; } else { $msg = "The Given string [$_POST[mainString]] do not ends with [$_POST[checkString]]"; } } } ?> <html> <body> <form action="index.php" method="POST"> <p>Input Main String</p> <input type="text" autocomplete="off" name="mainString" placeholder="Eg. Geeks for Geeks" required="true"> <p>Input String to be Checked</p> <input type="text" autocomplete="off" name="checkString" placeholder="Eg. Geek" required="true"><br> <select name="stringSearchType"> <option value=0>Starts With</option> <option value=1>Ends With</option> </select><br> <hr> <input type="submit" name="submit"> </form> <h2 style="color:green"> <?php if ($msg) { echo $msg; } ?> </h2> </body> </html> |
Input:
Input: Geeks For Geeks String To be Checked: Geek Type: Starts With Input: Geeks For Geeks String To be Checked: s Type: Ends With Input: Geeks For Geeks String To be Checked: For Type: Starts With
Output:
