The browser will recognise this as HTML and format the page as you tell it &#8211; here the <code>&lt;h2&gt;<\/code> tag will mean that the text <code>Hello World!<\/code> is formatted as a heading.<\/p>\n<p>As before we saw in the previous tutorial, the <code>&lt;?php<\/code> and <code>?&gt;<\/code> tags open execution of PHP code, the <code>echo<\/code> command says to output some text (i.e. send it to the browser), and we follow it with the string &#8220;<code>&lt;h1&gt;Hello World&lt;\/h1&gt;\"<\/code>, which contains HTML code.<\/p>\n<p>We should say that the above code doesn&#8217;t really utilise PHP to do anything interesting &#8211; it just prints out text, which you could have done with a static HTML page. However, we&#8217;ll be able to build on this to do more interesting things soon.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Special_Characters\"><\/span>Special Characters<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>You might need to output some characters such as quotation marks <code>\"<\/code> in your HTML, but you will notice that we used those to mark the start and end of the string above. So how does PHP distinguish between the <code>\"<\/code> which marks the start of the string, and that which is part of it? You can do this using a backslash (\\) before the quotation mark which is part of the string: <code>\\\"<\/code>. This is known as an <em>escape character<\/em>.<\/p>\n<p>Alternatively, you can use single quotes <code>'<\/code> to mark the start and end of the string, and double quotes within the string will be output without any special treatment. You can see these in the examples below, which both result in the same HTML being output:<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"php\">&lt;?php\r\necho '&lt;img src=\"hello.jpg\"&gt;';\r\necho \"&lt;img src=\\\"hello.jpg\\\"&gt;\";\r\n?&gt;<\/pre>\n<h2><span class=\"ez-toc-section\" id=\"Line_Breaks\"><\/span>Line Breaks<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you want to add a new line, you can do this using the <code>\\n<\/code> special character (in a string which starts and ends with <code>\"<\/code>. But remember, this will only show up in the <em>source code<\/em> of the page (which is the same as if you press enter when writing HTML code by hand), and won&#8217;t affect how it is shown to the visitor. If you want to add a new line which the visitor can see, use HTML to format it &#8211; such as the line break <em>&lt;br&gt;<\/em>.<\/p>\n<p>{% highlight php %}<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"php\">&lt;?php\r\necho \"&lt;p&gt;Hello \\nWorld&lt;\/p&gt;\";\r\necho \"&lt;p&gt;Hello &lt;br&gt;World&lt;\/p&gt;\";\r\n?&gt;<\/pre>\n<p>This example produces the following HTML source:<\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"html\">&lt;p&gt;Hello \r\nWorld&lt;\/p&gt;\r\n&lt;p&gt;Hello &lt;br&gt;World&lt;\/p&gt;<\/pre>\n<p>But it looks like the following to a visitor in a web browser &#8211; note the line breaks are different to those in the source code:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-109\" src=\"https:\/\/www.tiposaurus.co.uk\/wp-content\/uploads\/2023\/03\/hello_world_html2.png\" alt=\"hello world with line breaks\" width=\"194\" height=\"158\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this tutorial, I&#8217;ll show you how to output HTML from a PHP script.
