<?php
$file_content = file_get_contents(&#39;1.html&#39;);
$qiqi=str_replace("abc" , "000" ,$file_content);

$filename = &#39;1.html&#39;;
$somecontent = $qiqi;

// 首先我们要确定文件存在并且可写。
if (is_writable($filename)) {

// 在这个例子里,我们将使用添加模式打开$filename,
// 因此,文件指针将会在文件的开头,
// 那就是当我们使用fwrite()的时候,$somecontent将要写入的地方。
if (!$handle = fopen($filename, &#39;w&#39;)) {
echo "不能打开文件 $filename";
exit;
}

// 将$somecontent写入到我们打开的文件中。
if (fwrite($handle, $somecontent) === FALSE) {
echo "不能写入到文件 $filename";
exit;
}

echo "成功地将 $somecontent 写入到文件$filename";

fclose($handle);

} else {
echo "文件 $filename 不可写";
}
?>
