file_exists(): Checking file or directory

$add="images/119.jpg";
if(file_exists($add)){
echo "Yes file is there ";
}else{
	echo "Sorry no file at $add ";
}

Example 1: Checking for a File in a Subdirectory

<?php
$file_path = 'docs/sample.pdf';
if (file_exists($file_path)) {
    echo "File found: $file_path";
} else {
    echo "File not found.";
}
?>

Example 2: Checking Multiple Files in a Loop

<?php
$files = ['image1.jpg', 'image2.jpg', 'image3.jpg'];
foreach ($files as $file) {
    if (file_exists($file)) {
        echo "$file exists.<br>";
    } else {
        echo "$file does not exist.<br>";
    }
}
?>

Example 3: Using file_exists() for Directories

<?php
$dir = 'uploads';
if (file_exists($dir) && is_dir($dir)) {
    echo "Directory exists.";
} else {
    echo "Directory not found.";
}
?>
