Recursive FIle searching

[champrock]

Hi

 

I am trying to recursively search for a given file  from a directory and all the subdirectories in it. I am unable to figure out how to achieve that and output all instances of the file with the complete paths.

 

Can anyone please help me out in this? I searched php.net reference but somehow those code snippets mentioned do not return anything for me . Just a blank page.

 

thanks a lot for all the help.

I have this from a while ago which was used to find a file and then replace some text in it. You could modify if for your needs:

 

<?php
function find_file($dir,$file_to_find,$text_to_find,$replacement){
    $handler = opendir($dir);
    while(false !== ($file = readdir($handler))){
        if($file != '.' && $file != '..'){
            if(is_dir($dir.'/'.$file)){//if this is a directory, recall the function with the subdirectory defined
                $sub_dir = $dir.'/'.$file;
                find_file($sub_dir,$file_to_find,$text_to_find,$replacement);	
            }else{
                if($file==$file_to_find){//this is the file we are looking for
                	echo 'found';
                	$new_contents = str_replace($text_to_find,$replacement,file_get_contents($dir.'/'.$file));	
                	$h = fopen($dir.'/'.$file,'w');
                	fwrite($h,$new_contents);
                	fclose($h);
			}
            }	
        }
    }
}
echo find_file($_SERVER['DOCUMENT_ROOT'],'test.txt','test','blah');
?>
