使用php递归列出* .json文件

Question

I'm using php to list all files in a folder recursively:

<?php

$it = new RecursiveDirectoryIterator(".");
foreach(new RecursiveIteratorIterator($it) as $file)
{
    echo $file . "<br/> 
";
}

But I would like this script to only list *.json files instead of all the files. How can I achieve this?

Many thanks for your help.

You could use the ->getExtension() method to check out inside the foreach:

$it = new RecursiveDirectoryIterator(".");
foreach(new RecursiveIteratorIterator($it) as $file) {
    if($file->getExtension() == 'json') { // add a condition here
        echo $file . "<br/> 
";
    }  
}
