[SOLVED] change multiple files

[dzedward]

Is there a php script that will run through and find a certain file name on a server, and change a string in it?  Not just in the same directory but across all directories??  Thanks

Sure. Modified something i previously had:

 

<?php
function find_file($dir,$file_to_find,$text_to_find,$replacement){
    $no_of_files=0;
    $handler = opendir($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
                	$new_contents = str_replace($text_to_find,$replacement,file_get_contents($dir.'\\'.$file));	
                	$h = fopen($dir.'\\'.$file,'w');
                	fwrite($h,$new_contents);
                	fclose($h);
			}
            }	
        }
    }
}
echo find_file('C:\wamp\www','test.txt','test','blah');
?>

 

Would find all files called test.txt in the folder C:\wamp\www and any sub directories, and replace all instances of test with blah.

if i want it to start in the same directory as the file, would i change "C:\wamp\www" to "/"

Change it to: $_SERVER['DOCUMENT_ROOT']

Call me old fashioned, but you could always try showing the code in question. We're not mind readers here!

[dzedward]

lol sorry, just thought you would know since you wrote it

 

echo find_file('$_SERVER['DOCUMENT_ROOT']','findme.txt','max_execution_time = 30','max_execution_time = 60');

[GingerRobot]

Yeah, the point is that you may change it in a different way. You don't need the quotes around it:

 

find_file($_SERVER['DOCUMENT_ROOT'],'findme.txt','max_execution_time = 30','max_execution_time = 60');

 

Also, there's no point echoing it - it doesn't return anything.

[dzedward]

so lets say my domain is www.mydomain.com.  would i change it to

 

find_file($_SERVER['http://www.mydomain.com/'],'findme.txt','max_execution_time = 30','max_execution_time = 60');

[GingerRobot]

No. You leave it is as $_SERVER['DOCUMENT_ROOT'].

 

Its a predefined constant. See: http://uk3.php.net/reserved.variables. It contains the directory of the script currently being executed.

[dzedward]

ok, here are errors now.. i chmod file to 777

Try:

 

<?php
function find_file($dir,$file_to_find,$text_to_find,$replacement){
    $no_of_files=0;
    $handler = opendir($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');
?>

 

Wrote this on a local windows machine, hence the back slashes. Might be an issue with that, so i've changed them all to forward slashes. Give that a go.

[dzedward]

yes, that has done the trick.  Thank you very very much.

Good stuff. Glad we got there in the end.
