contents Search File Contents PHP code for searching directory text contents

This class can be used to search for files in a given text directory.
It can recursively find files with certain file extensions given a directory traversal.
And open the found files and check if they contain the search terms.
It returns a list of all files containing an array of search terms.

Copy the code The code is as follows:

/*
Class for searching the contents of all the files in a directory and its subdirectories

*/
class searchFileContents{
var $dir_name = '';//The directory to search
var $search_phrase = '';//The phrase to search in the file contents
var $allowed_file_types = array('php ','phps');//The file types that are searched
var $foundFiles;//Files that contain the search phrase will be stored here
//Open source code OSPHP.COM.Cn
var $myfiles;
function search ($directory, $search_phrase){
$this->dir_name = $directory;
$this->search_phrase = $search_phrase;
$this->myfiles = $this->GetDirContents($this-> dir_name);
$this->foundFiles = array();
if ( empty($this->search_phrase) ) die('Empty search phrase');
if ( empty($this->dir_name) ) die('You must select a directory to search');
foreach ( $this->myfiles as $f ){
if ( in_array(array_pop(explode ( '.', $f )), $this-> allowed_file_types) ){ //Open source OSPhP.COM.CN
$contents = file_get_contents($f);
if ( strpos($contents, $this->search_phrase) !== false )
$this->foundFiles [ ] = $f;
//Open source code OSPhP.COm.CN
}
}
return $this->foundFiles;
}
function GetDirContents($dir){
if (!is_dir($dir)){die ("Function GetDirContents: Problem reading : $dir!");}
if ($root=@opendir($dir)){
//PHP open source code
while ($file=readdir($root)){
if ($file=="." || $file==".."){continue;}
if(is_dir($dir."/".$file)){
$files=array_merge($files,$ this->GetDirContents($dir."/".$file));
}else{
$files[]=$dir."/".$file; //Open source OSPhP.COM.CN
}
}
}
return $files;
}
}
//Example:
$search = new searchFileContents;
$search->search('E:/htdocs/AccessClass', 'class'); //Open source code OSPHP .COM.Cn
var_dump($search->foundFiles);
?>

The above introduces the code of contents Search File Contents PHP to search the text content of the directory, including contents. I hope it will be helpful to friends who are interested in PHP tutorials.
