Example 1

Create an index array named $cars, assign three elements to it, and print the text containing the array value:

 <span class="token php language-php"><span class="token delimiter important"><?php</span>
<span class="token variable">$cars</span> <span class="token operator">=</span><span class="token keyword"></span></span><mark> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"Volvo"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"BMW"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"Toyota"</span> <span class="token punctuation">)</span></mark><span class="token punctuation"></span> <span class="token punctuation">;</span>
<span class="token keyword">echo</span> <span class="token string double-quoted-string">"I like "</span> <span class="token operator">.</span> <span class="token variable">$cars</span> <span class="token punctuation">[</span> <span class="token number">0</span> <span class="token punctuation">]</span> <span class="token operator">.</span> <span class="token string double-quoted-string">", "</span> <span class="token operator">.</span> <span class="token variable">$cars</span> <span class="token punctuation">[</span> <span class="token number">1</span> <span class="token punctuation">]</span> <span class="token operator">.</span> <span class="token string double-quoted-string">" and "</span> <span class="token operator">.</span> <span class="token variable">$cars</span> <span class="token punctuation">[</span> <span class="token number">2</span> <span class="token punctuation">]</span> <span class="token operator">.</span> <span class="token string double-quoted-string">"."</span> <span class="token punctuation">;</span>
<span class="token delimiter important">?></span>

Example 2

Create an associative array named $age:

 <span class="token php language-php"><span class="token delimiter important"><?php</span>
<span class="token variable">$age</span> <span class="token operator">=</span><span class="token keyword"></span></span><mark> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"Bill"</span> <span class="token operator">=></span> <span class="token string double-quoted-string">"60"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"Steve"</span> <span class="token operator">=></span> <span class="token string double-quoted-string">"56"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"Mark"</span> <span class="token operator">=></span> <span class="token string double-quoted-string">"31"</span> <span class="token punctuation">)</span></mark><span class="token punctuation"></span> <span class="token punctuation">;</span>

Example 3

Iterate over and print the value of the index array:

<span class="token variable">$cars</span> <span class="token operator">=</span><span class="token keyword"></span></span><mark> <span class="token keyword">array</span> <span class="token punctuation">(</span> <span class="token string double-quoted-string">"Volvo"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"BMW"</span> <span class="token punctuation">,</span> <span class="token string double-quoted-string">"Toyota"</span> <span class="token punctuation">)</span></mark><span class="token punctuation"></span> <span class="token punctuation">;</span>
