我知道在php中你可以在变量中嵌入变量,比如:
<? $var1 = "I\'m including {$var2} in this variable.."; ?>
但我想知道如何,以及是否可以在变量中包含一个函数.我知道我可以写:
<?php
$var1 = "I\'m including ";
$var1 .= somefunc();
$var1 = " in this variable..";
?>
但是如果我有一个很长的变量输出,我不想每次都这样做,或者我想使用多个函数:
<?php
$var1 = <<<EOF
<html lang="en">
<head>
<title>AAAHHHHH</title>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
</head>
<body>
There is <b>alot</b> of text and html here... but I want some <i>functions</i>!
-somefunc() doesn't work
-{somefunc()} doesn't work
-$somefunc() and {$somefunc()} doesn't work of course because a function needs to be a string
-more non-working: ${somefunc()}
</body> …
