這是我作PHPfunction函數的一點筆記:php
<body>ide
<?php
function writeMyName($fname)
{
echo $fname . " Yang.<br />";
}
echo "My name is ";
writeMyName("David");
echo "My name is ";
writeMyName("Mike");
echo "My name is ";
writeMyName("John");
//輸出不一樣的名字,但姓是相同的:
?>
<hr color="#FF0000">
<?php
function writeMyName1($fname,$punctuation)
{
echo $fname . " Yang" . $punctuation . "<br />";
}
echo "My name is ";
writeMyName1("David",".");
echo "My name is ";
writeMyName1("Mike","!");
echo "My name is ";
writeMyName1("John","...");
?>
<hr color="#FF0000">
<?php
function add($x,$y)
{
$total = $x + $y;
return $total;
}
echo "1 + 16 = " . add(1,16);
//PHP 函數 - 返回值,函數也能用於返回值
?>
</body>
