PHP automatically creates directories and saves file functions

PHP Save the file, you can also automatically create a directory based on the file path, the code is as follows (note: PHP to version 5 or more):

<?php
/**
* Save File
*
* @param string $fileName file name (including relative paths)
* @param string $text file contents
* @return Boolean
*/
function SaveFile ($fileName, $text) {
if (! $fileName | |! $text)
return false;
if (MakeDir (DirName ($fileName)) {
if ($fp = fopen ($fileName, "w")) {
if (@fwrite ($FP, $text)) {
Fclose ($FP);
return true;
} else {
Fclose ($FP);
return false;
}
}
}
return false;
}
/**
* Create a directory continuously
*
* $dir Directory string @param string
* @param int $mode permission number
* @return Boolean
*/
function MakeDir ($dir, $mode =0755) {
/*function MakeDir ($dir, $mode = "0777") {In addition, 0777 cannot add single and double quotes.
After the addition, "0400" = 600 permissions, the department thought it would be like this, I also think not to pass * *
if (!dir) return false;
if (!file_exists ($dir)) {
return mkdir ($dir, $mode, true);
} else {
return true;
}
}
?>
Here is the test content and call the above function
<?php
$content = ' Here is the test content ';
if (SaveFile (' Dir/test.txt ', $content)) {
Echo ' Write success ';
}else{
Echo ' Write Failed ';
}
?>

Note: MakeDir is a directory creation function, and we are using recursive creation.
