<b>Frage zum Einstieg</b>
|
||||
PHP läuft hinter rund drei Viertel aller Webseiten – inklusive WordPress, Wikipedia und Facebook. Aber wie sieht PHP-Code überhaupt aus, und wie startet man? In 15 Minuten kannst du dein erstes Programm schreiben.
|
||||
</div>
|
||||
|
||||
<!-- ===== SEKTION 1 ===== -->
|
||||
<h2>PHP starten</h2>
|
||||
|
||||
<p>PHP ist eine Programmiersprache, die auf deinem Computer oder einem Webserver läuft. Im Gegensatz zu HTML oder CSS wird PHP nicht im Browser angezeigt – es <i>erzeugt</i> Ausgaben (zum Beispiel HTML), die dann ausgeliefert werden.</p>
|
||||
|
||||
<p>Um anzufangen, brauchst du PHP auf deinem Computer. Auf Mac: <code class="inline">brew install php</code>. Auf Ubuntu: <code class="inline">apt install php8.4-cli</code>. Auf Windows: am einfachsten WSL2 mit Ubuntu darin nutzen.</p>
|
||||
|
||||
<p>PHP-Code lebt in Dateien mit der Endung <code class="inline">.php</code>. Lege eine Datei <code class="inline">hallo.php</code> an mit diesem Inhalt:</p>
|
||||
|
||||
<pre><span class="t"><?php</span>
|
||||
|
||||
<span class="k">echo</span> <span class="s">"Hallo Welt!"</span>;</pre>
|
||||
|
||||
<p>Die erste Zeile <code class="inline"><?php</code> sagt PHP: "ab hier kommt mein Code". Das Wort <code class="inline">echo</code> heißt: "gib das aus, was danach kommt". Strings (also Text) stehen in Anführungszeichen. Jede Anweisung endet mit einem Semikolon.</p>
|
||||
|
||||
<p>Im Terminal ausführen mit:</p>
|
||||
|
||||
<pre>php hallo.php</pre>
|
||||
|
||||
<p>Du siehst "Hallo Welt!" – dein erstes PHP-Programm läuft.</p>
|
||||
|
||||
<!-- ===== SEKTION 2 ===== -->
|
||||
<h2>Variablen</h2>
|
||||
|
||||
<p>Eine <b>Variable</b> ist ein benannter Platz, an dem du einen Wert speicherst. In PHP beginnen Variablen immer mit einem Dollar-Zeichen <code class="inline">$</code>. Das macht sie im Code sofort erkennbar:</p>
|
||||
|
||||
<pre><span class="t"><?php</span>
|
||||
|
||||
<span class="v">$name</span> = <span class="s">"Marek"</span>;
|
||||
<span class="v">$alter</span> = <span class="s">34</span>;
|
||||
<span class="v">$istAktiv</span> = <span class="k">true</span>;
|
||||
|
||||
<span class="k">echo</span> <span class="v">$name</span>;</pre>
|
||||
|
||||
<p>Variablen können verschiedene Arten von Werten enthalten. Die drei wichtigsten:</p>
|
||||
|
||||
<ul>
|
||||
<li><b>Strings</b> – Text in Anführungszeichen, z.B. <code class="inline">"Hallo"</code></li>
|
||||
<li><b>Zahlen</b> – ganze Zahlen (<code class="inline">42</code>) oder Kommazahlen (<code class="inline">3.14</code>)</li>
|
||||
<li><b>Wahrheitswerte</b> – <code class="inline">true</code> (wahr) oder <code class="inline">false</code> (falsch)</li>
|
||||
</ul>
|
||||

<p>Mit dem Punkt verbindest du Strings:</p>

|

<!-- ===== SEKTION 3 ===== -->
|
||||
<h2>Bedingungen</h2>
|
||||
|
||||
<p>Programme müssen oft entscheiden: "wenn X zutrifft, mach Y, sonst Z". Dafür gibt es <code class="inline">if</code> und <code class="inline">else</code>:</p>
|
||||
|
||||
<pre><span class="v">$alter</span> = <span class="s">17</span>;
|
||||
|
||||
<span class="k">if</span> (<span class="v">$alter</span> >= <span class="s">18</span>) {
|
||||
<span class="k">echo</span> <span class="s">"Du bist erwachsen."</span>;
|
||||
} <span class="k">else</span> {
|
||||
<span class="k">echo</span> <span class="s">"Du bist noch minderjährig."</span>;
|
||||
}</pre>
|
||||
|
||||
<p>Die Klammer hinter <code class="inline">if</code> enthält die Bedingung. Die geschweiften Klammern <code class="inline">{ }</code> umschließen den Code, der ausgeführt wird, wenn die Bedingung wahr ist. <code class="inline">else</code> ist der Block, wenn sie falsch ist.</p>
|
||||
|
||||
<p>Wichtige Vergleichs-Operatoren:</p>
|
||||
|
||||
<ul>
|
||||
<li><code class="inline">==</code> gleich</li>
|
||||
<li><code class="inline">!=</code> ungleich</li>
|
||||
<li><code class="inline"><</code>, <code class="inline">></code> kleiner, größer</li>
|
||||
<li><code class="inline"><=</code>, <code class="inline">>=</code> kleiner-gleich, größer-gleich</li>
|
||||
</ul>

<b>Ein Gleichheitszeichen reicht nicht</b>
|
||||
Zum Zuweisen nutzt du <code class="inline">=</code> (ein Gleichheitszeichen). Zum Vergleichen brauchst du <code class="inline">==</code> (zwei). Das ist eine häufige Verwechslung bei Anfängern.

<!-- ===== SEKTION 4 ===== -->
|
||||
<h2>Listen und Schleifen</h2>
|
||||
|
||||
<p>Mehrere Werte fasst du in einer <b>Liste</b> zusammen. In PHP heißen Listen <code class="inline">array</code>:</p>
|
||||
|
||||
<pre><span class="v">$obst</span> = [<span class="s">"Apfel"</span>, <span class="s">"Birne"</span>, <span class="s">"Kirsche"</span>];</pre>
|
||||
|
||||
<p>Über jede Liste kannst du mit <code class="inline">foreach</code> Schritt für Schritt gehen:</p>
|
||||
|
||||
<pre><span class="k">foreach</span> (<span class="v">$obst</span> <span class="k">as</span> <span class="v">$frucht</span>) {
|
||||
<span class="k">echo</span> <span class="v">$frucht</span> . <span class="s">"\n"</span>;
|
||||
}</pre>
|
||||
|
||||
<p>Das gibt "Apfel", "Birne", "Kirsche" untereinander aus. Das <code class="inline">\n</code> ist ein Zeilenumbruch. Die Variable <code class="inline">$frucht</code> bekommt bei jedem Durchlauf den nächsten Wert aus der Liste.</p>
|
||||
|
||||
<p>Listen müssen nicht aus Strings bestehen. Zahlen gehen genauso:</p>
|
||||
|
||||
<pre><span class="v">$zahlen</span> = [<span class="s">10</span>, <span class="s">20</span>, <span class="s">30</span>];
|
||||
<span class="v">$summe</span> = <span class="s">0</span>;
|
||||
|
||||
<span class="k">foreach</span> (<span class="v">$zahlen</span> <span class="k">as</span> <span class="v">$zahl</span>) {
|
||||
<span class="v">$summe</span> = <span class="v">$summe</span> + <span class="v">$zahl</span>;
|
||||
}
|
||||
|
||||
<span class="k">echo</span> <span class="v">$summe</span>; <span class="c">// 60</span></pre>
|
||||
|
||||
<!-- ===== SEKTION 5 ===== -->
|
||||
<h2>Funktionen</h2>
|
||||
|
||||
<p>Wenn du denselben Code mehrfach brauchst, packst du ihn in eine <b>Funktion</b>. Du gibst der Funktion einen Namen und kannst sie dann beliebig oft aufrufen:</p>
|
||||
|
||||
<pre><span class="k">function</span> <span class="f">begruessen</span>(<span class="v">$name</span>) {
|
||||
<span class="k">echo</span> <span class="s">"Hallo, "</span> . <span class="v">$name</span> . <span class="s">"!\n"</span>;
|
||||
}
|
||||
|
||||
<span class="f">begruessen</span>(<span class="s">"Marek"</span>);
|
||||
<span class="f">begruessen</span>(<span class="s">"Anna"</span>);
|
||||
<span class="f">begruessen</span>(<span class="s">"Tom"</span>);</pre>
|
||||
|
||||
<p>Die Funktion <code class="inline">begruessen</code> nimmt einen <b>Parameter</b> entgegen (<code class="inline">$name</code>). Beim Aufruf übergibst du den konkreten Wert in den Klammern.</p>
|
||||
|
||||
<p>Funktionen können auch Werte <b>zurückgeben</b>. Dafür gibt es <code class="inline">return</code>:</p>
|
||||
|
||||
<pre><span class="k">function</span> <span class="f">addiere</span>(<span class="v">$a</span>, <span class="v">$b</span>) {
|
||||
<span class="k">return</span> <span class="v">$a</span> + <span class="v">$b</span>;
|
||||
}
|
||||
|
||||
<span class="v">$ergebnis</span> = <span class="f">addiere</span>(<span class="s">3</span>, <span class="s">5</span>);
|
||||
<span class="k">echo</span> <span class="v">$ergebnis</span>; <span class="c">// 8</span></pre>
|
||||
|
||||
<p>Die Funktion macht ihre Berechnung und liefert das Ergebnis zurück. Du fängst es in einer Variable auf und kannst damit weiterarbeiten.</p>

<b>Übung macht den Meister</b>
|

Schreibe jetzt selbst ein kleines PHP-Programm. Zum Beispiel: eine Liste deiner Lieblings-Filme, die mit <code class="inline">foreach</code> ausgegeben werden. Oder eine Funktion, die das Doppelte einer Zahl zurückgibt. Praktisch ausprobieren ist der schnellste Weg, PHP zu lernen.
