上面例子中可以看到只有键值对 <literal>"a" =>
|
|
"green"</literal> 在两个数组中都存在从而被返回。值
|
|
<literal>"red"</literal> 没有被返回是因为在
|
|
<varname>$array1</varname> 中它的键名是 <literal>0</literal>
|
|
而在 <varname>$array2</varname> 中 <literal>"red"</literal>
|
|
的键名是 <literal>1</literal>，键 <literal>"b"</literal> 没有返回的原因是它的值和其他数组不同。
|
|
</simpara>
|
|
<simpara>
|
|
键值对 <literal>key => value</literal>
|
|
中的两个值仅在 <literal>(string) $elem1 === (string)
|
|
$elem2 </literal> 时被认为相等。也就是说使用了严格检查，字符串的表达必须相同。
