Avoid building the same page 50 times-CodePudding

The problem I have is quite logic, but I have never thought of it before and I can not find any documentation about it:

The user will click on the city that he/she wants to get the service from (a city in the UK), but the pages of the cities are all the same with only two differences:

The title which specifies the city.

The phone number,which the user will call the company.

<li >
    <a href="eletricalpage.php">Electrical</a>
    <ul>
        <li >
    <a href="#">LONDON</a>
    <ul>
        <li><a href="#">Lewisham</a></li>
        <li><a href="#">Greenwich</a></li>
    </ul>
</li>
<li >
    <a href="#">SOUTH EAST</a>
    <ul>
        <li><a href="#">Berkshire</a></li>
        <li><a href="#">Southampton</a></li>
        <li><a href="#">Guildford</a></li>
        <li><a href="#">Maidstone</a></li>
        <li><a href="#">Brighton</a></li>
    </ul>
</li>
<li >
    <a href="#">SOUTH WEST</a>
    <ul>
        <li><a href="#">Bristol</a></li>
        <li><a href="#">Swindon</a></li>
    </ul>
</li>

Is there any way to avoid building 50 pages for the cities that the company offers its services in? I want to build only one page and then when the user clicks on the city, the page with the changed title and the changed number shows up. I want to get this done in PHP.

You can do as little as create an array containing cities names and the phone number in the pages' script. Later, you can use the global variable $_GET to get the requested city via HTTP GET request to the page.

<?php
$cityPhoneNumbers = [
    "London" => "1234-555-1234",
    "Manchester" => "1266-555-4321",
];
$requestedCity = $_GET["city"];
if (!empty($requestedCity)) {
    if (!empty($cityPhoneNumbers[$requestedCity])) { ?>
        Our number in <?=htmlspecialchars($requestedCity) ?> is <?= $cityPhoneNumbers[
     $requestedCity
 ] ?>
        <?php }
}
?>

You can now link to this page like this: /number.php?city=London To avoid using the question mark in your URL you may use Apache mod_rewrite or similar.

Try this:

php:

// getInfo.php

<?php
$cities = [
  'Lewisham' => ['title' => 'Title for Lewisham', 'phone_number' => ' 41xxxxxxx'],
  'Greenwich' => ['title' => 'Title for Greenwich', 'phone_number' => ' 41xxxxxxx'],
  // And more...
];

// Get the city name from input
$city = htmlspecialchars($_GET['city']);

// Get the city information from your data
$city_info = $cities[$city];

if(!$city_info){
    exit(404);
}

// Include your single page to display information
include "displayInfo.php";

php:

// displayInfo.php

<html>
    <head>
        <title><?=$city_info['title']?></title>
    </head>
    <body>
        Phone number in <?=$city?> is: <?=$city_info['phone_number']?>
    </body>
</html>

And in your html you should link the cities to the getInfo.php file like this:

<li><a href="getInfo.php?city=Lewisham">Lewisham</a></li>
