so what I need here is to list specific extiontion only. php files only
right now my code lists all files in same folder
<?php
function get_string_between($string, $start, $end){
$string = ' ' . $string;
$ini = strpos($string, $start);
if ($ini == 0) return '';
$ini += strlen($start);
$len = strpos($string, $end, $ini) - $ini;
return substr($string, $ini, $len);
}
$files1 = scandir(dirname(__FILE__));
?>
<?php
foreach($files1 as $myfile){
if($myfile!='.' && $myfile!='..' && $myfile!='index.php'){
$value = file_get_contents($myfile);
$fullstring = $value;
$parsed = get_string_between($fullstring, '$Cont1 = \'', '\'');
$parsed1 = get_string_between($fullstring, '$Con2 = \'', '\'');
?>
<?php
}
}
?>
can some one please post an answer with editing this and show me how do I make it to list php files only?

Answer 1

Hope this helps. It will only read files which filenames end with php
<?php
function get_string_between($string, $start, $end){
$string = ' ' . $string;
$ini = strpos($string, $start);
if ($ini == 0) return '';
$ini += strlen($start);
$len = strpos($string, $end, $ini) - $ini;
return substr($string, $ini, $len);
}
$files1 = scandir(dirname(__FILE__));
?>
<?php
foreach($files1 as $myfile){
if (substr($myfile, -3) != "php")
continue;
if($myfile!='.' && $myfile!='..' && $myfile!='index.php'){
$value = file_get_contents($myfile);
$fullstring = $value;
$parsed = get_string_between($fullstring, '$Cont1 = \'', '\'');
$parsed1 = get_string_between($fullstring, '$Con2 = \'', '\'');
?>
<?php
}
}
?>

glob() is pretty much made to do this exactly, and it avoids regex in a loop, substringing on an arbitrary number of chars, etc.
foreach (glob("*.php") as $script) {
echo "$script size " . filesize($script) . PHP_EOL;
}

Answer 3

Something like this ( untested )
$Dir = new DirectoryIterator($dir);
$iterator = new RegexIterator($Dir, '/\.php$/i', RegexIterator::MATCH);
foreach($iterator as $fileinfo) {
if ($fileinfo->isDot()) continue;
var_dump( $fileinfo );
}
Or even better
$Dir = new FilesystemIterator(__DIR__, FilesystemIterator::SKIP_DOTS | FilesystemIterator::UNIX_PATHS | FilesystemIterator::KEY_AS_PATHNAME );
$iterator = new RegexIterator($Dir, '/\.php$/i', RegexIterator::MATCH);
foreach($iterator as $fileinfo) {
if ($fileinfo->isDot()) continue;
var_dump( $fileinfo );
}
This second one lets you skip the dots ('.', '..' etc) and changes all the \ Windows to / Linux style ( mainly for use on windows ), auto-magically.
