谢谢jakey9826! 我这样写: if (ereg($it,$file)) //4 unlink("kk/$file"); 他痛痛快快地把所有含"abc"的文件名都删了, 可这样写就不对: if (ereg($it,$file)) //4 $a=$file; “pattern要用正则表达式的方式”,这个应该怎样写呢?谢谢!
另外,怎样在所有含"abc"的文件中找到最后传上去的那个文件?谢谢!
多看看手册吧, 如果只是搜索abc没有必要用正则.最后上传的文件,可以通过查看文件的最后修改日期.$file = 'somefile.txt';// set up basic connection $conn_id = ftp_connect($ftp_server);// login with username and password $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);// get the last modified time $buff = ftp_mdtm($conn_id, $file);if ($buff != -1) { // somefile.txt was last modified on: March 26 2003 14:16:41. echo "$file was last modified on : " . date("F d Y H:i:s.", $buff); } else { echo "Couldn't get mdtime"; }// close the connection ftp_close($conn_id);
$conn_id = ftp_connect($ftp_server);// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);// get contents of the current directory
$contents = ftp_nlist($conn_id, ".");
$strContent = implode("****", $contents);
if(preg_match("/abc/i", $strContent))
{
echo "true";
}
else
{
echo false;
}
$dir = 'dirname';
function view_dir($directory)
{
$handle = opendir( $directory );
while ( $file = readdir($handle) )

$bdir = $directory . '/' .$file;
if ($file <> '.' && $file <> '..' && is_dir($bdir))
{
view_dir( $directory .'/'. $file);
}
else if( $file <> '.' && $file <> '..')
{
$return[] = $directory .'/'. $file;
if($file=='abc'){
$exist = 1;

$exist = 0;

closedir( $handle );

Warning: ereg() [function.ereg]: REG_EMPTY in...on line 4$it="abc";
$dir0=opendir('kk');
while($file=readdir($dir0)){
if (ereg($it,$file)) //4
$a=$file;
}我慢慢消化楼上朋友们说的,请纠正我的错误,谢谢!
2 ereg函数,第一个参数是$pattern,第二个参数是查询的字符串.
pattern要用正则表达式的方式.
我这样写:
if (ereg($it,$file)) //4
unlink("kk/$file");
他痛痛快快地把所有含"abc"的文件名都删了,
可这样写就不对:
if (ereg($it,$file)) //4
$a=$file;
“pattern要用正则表达式的方式”,这个应该怎样写呢?谢谢!
