Generate URL-Friendly Slugs from Unicode Strings in PHP
Creating slugs from Unicode strings is crucial for generating SEO-friendly URLs. In PHP, a slugification function can be implemented to convert strings like "Andrés Cortez" to "andres-cortez."
To achieve this, consider using a more efficient approach compared to repetitive replacements. The following function provides a solution:
public static function slugify($text, string $divider = '-')
{
// Replace non-letter or digits with the specified divider
$text = preg_replace('~[^\pL\d]+~u', $divider, $text);
// Transliterate to US-ASCII
$text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
// Remove unwanted characters
$text = preg_replace('~[^-\w]+~', '', $text);
// Trim and remove duplicate dividers
$text = trim($text, $divider);
$text = preg_replace('~-+~', $divider, $text);
// Convert to lowercase
$text = strtolower($text);
// Default to 'n-a' if the slug is empty
if (empty($text)) {
return 'n-a';
}
return $text;
}
This function follows a structured approach:
- Non-letter or digit characters are replaced with the specified divider.
- Unicode characters are transliterated to US-ASCII for compatibility.
- Unwanted characters are removed, such as spaces and special characters.
- Leading and trailing dividers are trimmed, and duplicate dividers are eliminated.
- The slug is converted to lowercase.
- An empty slug defaults to 'n-a' to avoid empty URLs.
By utilizing this efficient slugification function, you can effortlessly generate URL-friendly slugs from Unicode strings in your PHP applications.

Jun 24, 2025 am 12:53 AM
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1.

How do I use page caching in PHP?
Jun 24, 2025 am 12:50 AM
PHP page caching improves website performance by reducing server load and speeding up page loading. 1. Basic file cache avoids repeated generation of dynamic content by generating static HTML files and providing services during the validity period; 2. Enable OPcache to compile PHP scripts into bytecode and store them in memory, improving execution efficiency; 3. For dynamic pages with parameters, they should be cached separately according to URL parameters, and avoid cached user-specific content; 4. Lightweight cache libraries such as PHPFastCache can be used to simplify development and support multiple storage drivers. Combining these methods can effectively optimize the caching strategy of PHP projects.
