php界定符就是为了照样输出内容。它的格式如下:


$str = <<< EOF
    Here is your string
    ......
EOF;

其中EOF是自定义的变量,但要成对出现!

附上一段php示例代码:


<?php
$a = "www.phperz.com";
print <<< phperz
<select>
 <option value="1">第一项</option>
</select>
这里是{$var}的php教程
phperz;
?>

使用php定界符技巧总结:

1.结尾,如上例phperz;必须另起一行,否则出现错误。

2.定界符内的php变量一定要像这种{$a}模式,否则不会识别。
