# SplFileObject::fgetss

(PHP 5 >= 5.1.0, PHP 7)

SplFileObject::fgetss — Gets line from file and strip HTML tags

警告

本函数已自 PHP 7.3.0 起弃用，自 PHP 8.0.0 起移除。强烈建议不要依赖本函数。

### 说明

public SplFileObject::fgetss(string `$allowable_tags` = ?): string

Identical to SplFileObject::fgets(), except that SplFileObject::fgetss() attempts to strip any HTML and PHP tags from the text it reads. The function retains the parsing state from call to call, and as such is not equivalent to calling strip_tags() on the return value of SplFileObject::fgets().

### 参数

`allowable_tags`

  Optional parameter to specify tags which should not be stripped.

### 返回值

Returns a string containing the next line of the file with HTML and PHP code stripped, or `false` on error.

### 示例

示例 #1 SplFileObject::fgetss() example

`<?php
$str = <<<EOD
<html><body>
<p>Welcome! Today is the <?php echo(date('jS')); ?> of <?= date('F'); ?>.</p>
</body></html>
Text outside of the HTML block.
EOD;
file_put_contents("sample.php", $str);
$file = new SplFileObject("sample.php");
while (!$file->eof()) {
echo $file->fgetss();
}
?>`

以上示例的输出类似于：

    Welcome! Today is the  of .

    Text outside of the HTML block.
