使用PHP递归搜索目录中的文件并更改值

Question

I have some php that's replacing color values in css files in a directory. It works fine except that it only searches for css files in the main directory. I've been searching but cant seem to find a simple way to make this recursive. Any ideas?

I'm currently using $arr=glob("themes/Evolution/*.css");

An example folder structure with css files are.

Main Dir > Style.css
Main Dir > Folder 1 > mycss.css
Main Dir > Folder 2 > mycss.css
Main Dir > Folder 3 > mycss.css

 //Read default color from INI $lines_array = file("modules/evolution/evolution.ini"); $search_string = "currentcolor"; foreach($lines_array as $line) { if(strpos($line, $search_string) !== false) { list(, $new_str) = explode("=", $line); $new_str = trim($new_str); //This line removes the spaces before and after. } } $inicurrentcolor = $new_str; //code to change css color if(isset($_REQUEST['resetcolor'])){ $arr=glob("themes/Evolution/*.css"); //your css file's path $textboxdefaultcolorcode=$_POST['defaultcolor']; foreach($arr as $key=>$val){ $str=file_get_contents($val); $str=str_replace($inicurrentcolor, $textboxdefaultcolorcode, $str); file_put_contents($val, $str); } } <div class="colorbox"> <br> <label id="steps">Reset Evolution theme color back to the default color.</label> <br> <br> <Form name="default1" method="POST" action="home.php?m=evolution"> <label for="color1">Default Theme Color: </label><input style="background-color:#379BB9; color:#ffffff" type="text" id="defaultcolor" name="defaultcolor" value="#379BB9" readonly> <br> <br> <input type="submit" name="resetcolor" value="Reset Theme Color"> </form> <br> </div>

I figured out the answer with some help. The code below will allow you to search recursively with the code above. Hope this helps.

 $themedir = 'themes/Evolution'; $allFiles = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($themedir)); $cssFiles = new RegexIterator($allFiles, '/\\.css$/i'); if(isset($_REQUEST['resetcolor'])){ $textboxdefaultcolorcode=$_POST['defaultcolor']; //added line foreach($cssFiles as $cssFile=>$val){ $str=file_get_contents($val); $str=str_replace($inicurrentcolor, $textboxdefaultcolorcode, $str); file_put_contents($val, $str); } }
