本文介绍下，php搜索文件并列出搜索到的文件名的一例代码，供初学的朋友参考。
先来看一个简单的php搜索文件并显示的代码。
如下：
下面是功能更强，复杂点的。
.*<\/title>/i", $fileContent, $matchResult);
$title = preg_replace(array("/()/i","/(<\/title>)/i"), "", $matchResult[0]);
if (empty($title)) {
return $default;
} else {
return $title;
}
}
//获取文件描述信息
function getFileDescribe($file,$length=200, $default="None describe")
{
$metas = get_meta_tags($file);
if ($meta['description'] != "") {
return $metas['description'];
}
$fileContent = getFileContent($file);
preg_match("/(<body.*<\/body>)/is", $fileContent, $matchResult);
$pattern = array("/(<[^\x80-\xff]+>)/i","/(<input.*>)+/i", "/()+/i", "/(<img.*>)+/i",
"/([<script.*>])+.*([<\/script>])+/i","/&/i","/"/i","/'/i", "/\s/");
$description = preg_replace($pattern, "", $matchResult[0]);
$description = mb_substr($description, 0, $length)." ...";
return $description;
}
//加亮搜索结果中的关键字
function highLightKeyword($text, $keyword, $color="#C60A00")
{
$newword = "<font color=$color>$keyword</font>";
$text = str_replace($keyword, $newword, $text);
return $text;
}
//获取文件大小(KB)
function getFileSize($file)
{
$filesize = intval(filesize($file)/1024)."K";
return $filesize;
}
//获取文件最后修改的时间
function getFileTime($file)
{
$filetime = date("Y-m-d", filemtime($file));
return $filetime;
}
//搜索目录下所有文件
function searchFile($dir, $keyword)
{
$sFile = getFile($dir);
if (count($sFile) <= 0) {
return false;
}
$sResult = array();
foreach ($sFile as $file) {
if (searchText($file, $keyword)) {
$sResult[] = $file;
}
}
if (count($sResult) <= 0) {
return false;
} else {
return $sResult;
}
} //by bbs.it-home.org
/* 测试代码 */
//指定要搜索的目录
$dir = "./php_Linux";
//要搜索的关键字
$keyword = "sendmail";
$fileArr = searchFile($dir, $keyword);
$searchSum = count($fileArr);
echo "搜索关键字: <b>$keyword</b> 搜索目录: <b>$dir</b> 搜索结果: <b>$searchSum</b><br><hr size=1><br>";
if ($searchSum <= 0) {
echo "没有搜索到任何结果";
} else {
foreach ($fileArr as $file) {
echo "". highLightKeyword(getFileTitle($file), $keyword) .
" - ".getFileSize($file)." ". getFileTime($file) .
"<br>\n<font size=2>".highLightKeyword(getFileDescribe($file), $keyword) .
"</font><br><br>";
}
}
