PHP bulk Delete, purge UTF-8 file BOM Header code example _php tutorial

Remember to back up the files before running the code oh, to avoid failure problems.

Code One:
Copy CodeThe code is as follows:
function Checkbom ($filename) {
Global $auto;
$contents = file_get_contents ($filename);
$charset [1] = substr ($contents, 0, 1);
$charset [2] = substr ($contents, 1, 1);
$charset [3] = substr ($contents, 2, 1);
if (Ord ($charset [1]) = = 239 && ord ($charset [2]) = = 187 && ord ($charset [3]) = = 191) {
if ($auto = = 1) {
$rest = substr ($contents, 3);
Rewrite ($filename, $rest);
Return ("BOM found, automatically removed.");
} else {
Return ("BOM found.");
}
}
else return ("BOM not Found.");
}

Code two:
Copy the Code code as follows:
Header (' content-type:text/html; Charset=utf-8 ');
if (Isset ($_get[' dir '))) {//Set file directory, if not set, automatically set to the directory where the current file is located
$basedir =$_get[' dir '];
}else{
$basedir = '. ';
}
$auto =1;/* is set to 1 mark to detect BOM and remove, set to 0 mark only for BOM detection, do not remove */

Echo ' Currently looking for directory is: '. $basedir. ' The current setting is: ';
echo $auto? ' Detects the BOM of a BOM while removing the bill of documentation
': ' Only detect file BOM does not perform removal of BOM operation
';

Checkdir ($basedir);
function Checkdir ($basedir) {
if ($dh =opendir ($basedir)) {
while (($file =readdir ($DH))!== false) {
if ($file! = '. ' && $file! = ' ... ') {
if (!is_dir ($basedir. ' /'. $file)) {
echo ' file: '. $basedir. ' /'. $file. Checkbom ($basedir. ' /'. $file). '
';
}else{
$dirname = $basedir. ' /'. $file;
Checkdir ($dirname);
}
}
}
Closedir ($DH);
}
}
function Checkbom ($filename) {
Global $auto;
$contents =file_get_contents ($filename);
$charset [1]=substr ($contents, 0, 1);
$charset [2]=substr ($contents, 1, 1);
$charset [3]=substr ($contents, 2, 1);
if (Ord ($charset [1]) ==239 && ord ($charset [2]) ==187 && ord ($charset [3]) ==191) {
if ($auto ==1) {
$rest =substr ($contents, 3);
Rewrite ($filename, $rest);
Return (' Find BOM and automatically remove ');
}else{
Return (' Find BOM ');
}
}else{
Return (' No BOM found ');
}
}
function rewrite ($filename, $data) {
$filenum =fopen ($filename, ' w ');
Flock ($filenum, LOCK_EX);
Fwrite ($filenum, $data);
Fclose ($filenum);
}
?>

Code Three:
Copy the Code code as follows:
# #把该文件放在需求去除BOM头的目录下跑一下却可.
if (Isset ($_get [' dir '])) {//config the Basedir
$basedir = $_get [' dir '];
} else {
$basedir = '. ';
}

$auto = 1;

Checkdir ($basedir);
function Checkdir ($basedir) {
if ($dh = Opendir ($basedir)) {
while (($file = Readdir ($DH))!== false) {
if ($file! = '. ' && $file! = ' ... ') {
if (! Is_dir ($basedir. "/" . $file)) {//If it is a file
echo "FileName: $basedir/$file". Checkbom ("$basedir/$file"). "
";
} else {
$dirname = $basedir. "/" . $file; If the directory
Checkdir ($dirname); Recursive
}
}
}
Closedir ($DH);
}
}
function Checkbom ($filename) {
Global $auto;
$contents = file_get_contents ($filename);
$charset [1] = substr ($contents, 0, 1);
$charset [2] = substr ($contents, 1, 1);
$charset [3] = substr ($contents, 2, 1);
if (Ord ($charset [1]) = = 239 && ord ($charset [2]) = = 187 && ord ($charset [3]) = = 191) {//BOM
The first three characters of the ASCII
The codes were
239
187
191
if ($auto = = 1) {
$rest = substr ($contents, 3);
Rewrite ($filename, $rest);
Return ("BOM found, automatically removed.");
} else {
Return ("BOM found.");
}
} else
Return ("BOM not Found.");
}
function rewrite ($filename, $data) {
$filenum = fopen ($filename, "w");
Flock ($filenum, LOCK_EX);
Fwrite ($filenum, $data);
Fclose ($filenum);
}
?>

Second, Python
Copy the Code code as follows:
#!/usr/bin/env python
#-*-Coding:utf-8-*-

Import OS

Def Delbom ():
File_count = 0
Bom_files = []

For Dirpath, Dirnames, filenames in Os.walk ('. '):
if (len (filenames)):
For filename in filenames:
File_count + = 1
File = open (Dirpath + "/" + filename, ' r+ ')
File_contents = File.read ()

if (len (file_contents) > 3):
if (Ord (file_contents[0]) = = 239 and ord (file_contents[1]) = = 187 and ord (file_contents[2]) = = 191):
Bom_files.append (Dirpath + "/" + filename)
File.seek (0)
File.write (file_contents[3:])
Print bom_files[-1], "BOM found. Deleted. "
File.close ()

Print File_count, "file (s) found.", Len (bom_files), "file (s) has a BOM." Deleted. "

if __name__ = = "__main__":
Delbom ()
