Question

I know this question is probably straightfoward but I’m new to php and programming…
I want to write the results of a recursive search to a text file, and also ensuring that any other search performed will not overwrite the exisiting data, but add to it.

here is my code:

 <?php 

$it = new RecursiveDirectoryIterator("L:\folder\folder\folder"); 
$display = Array ( 'jpeg', 'jpg', 'tif', 'tiff', 'bmp', 'shp', 'gif', 'png' ); 
foreach(new RecursiveIteratorIterator($it) as $file) 
{ 
    if ( In_Array ( SubStr ( $file, StrrPos ( $file, '.' ) + 1 ), $display ) == true )
    { 
        echo $file . "<br/> \n"; 
    }
}

?>

So instead of echoing the result, I’d rather it be written to a text file. Also, if it is possible, echo the result and write it to a text file. plz let me know what code I can add in to achieve this thanks 🙂

Try with:

<?php 

$it = new RecursiveDirectoryIterator("L:\folder\folder\folder"); 
$display = Array ( 'jpeg', 'jpg', 'tif', 'tiff', 'bmp', 'shp', 'gif', 'png' ); 

$fp = fopen("output.txt", "a");

foreach(new RecursiveIteratorIterator($it) as $file) 
{ 
    if ( In_Array ( SubStr ( $file, StrrPos ( $file, '.' ) + 1 ), $display ) == true )
    { 
        //echo $file . "<br/> \n"; 
        fwrite($fp, $file."\n");
    }
}

fclose($fp);
?>
