compact

Beispiel

Beispiel 1

Erstellen Sie ein Array, das Variablennamen und deren Werte enthält:

 <span class="token php language-php"><span class="token delimiter important"><? Php</span>
<span class="token variable">$ firstname</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"bill"</span> <span class="token punctuation">;</span>
<span class="token variable">$ lastname</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"gates"</span> <span class="token punctuation">;</span>
<span class="token variable">$ ay</span> <span class="token operator">"</span> <span class="token string double-quoted-string">60"</span> <span class="token punctuation">;</span>

<span class="token variable">$ result</span> <span class="token operator">=</span><span class="token function"></span></span><mark> <span class="token function">Compact</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"FirstName"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"LastName"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"Age"</span> <span class="token punctuation">)</span></mark><span class="token punctuation"></span> <span class="token punctuation">;</span>

<span class="token function">print_r</span> <span class="token punctuation">(</span> <span class="token variable">$ result</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>
<span class="token delimiter important">?></span>

Probieren Sie es selbst aus

Beispiel 2

Verwenden Sie eine Zeichenfolge, die nicht mit der Variablen übereinstimmt, und eine Reihe von Variablennamen:

 <span class="token php language-php"><span class="token delimiter important"><? Php</span>
<span class="token variable">$ firstname</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"bill"</span> <span class="token punctuation">;</span>
<span class="token variable">$ lastname</span> <span class="token operator">=</span> <span class="token string double-quoted-string">"gates"</span> <span class="token punctuation">;</span>
<span class="token variable">$ ay</span> <span class="token operator">"</span> <span class="token string double-quoted-string">60"</span> <span class="token punctuation">;</span>

<span class="token variable">$ name</span> <span class="token operator">=</span> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"FirstName"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"LastName"</span> <span class="token punctuation">)</span> <span class="token punctuation">;</span>
