Question

here is the content of my original zip:

• admin/
• images/
• include/
• index.php
• install.php
• styles/
• template/
• upload/
• web/

If i run this code:

$zip = new ZipArchive;
    if ($zip->open('update.zip') === TRUE) {

        $zip->deleteName('include/mysql.php');
        $zip->deleteName('install.php');

        $zip->extractTo('./update/');

        $zip->close();

        unlink('./update.zip');

    } else {
        echo 'Fehler';
    }

the files that are left are:

• admin/
• images/
• include/

all others are deleted. Any idea why?

Answer 1

Try to close the ZIP file after deleteName(), then open again to extract.

<?php
$zip = new ZipArchive;
if ($zip->open('update.zip') === TRUE) {

    $zip->deleteName('include/mysql.php');
    $zip->deleteName('install.php');
    $zip->close();

    $zip->open('update.zip');
    $zip->extractTo('./update/');
    $zip->close();

    unlink('./update.zip');

} else {
    echo 'Fehler';
}
?>
