In this blog, we will learn how to convert slugified file paths into readable strings in PHP using simple methods.

Introduction:

In web development, slugifying file paths is a common practice to create SEO-friendly URLs or to sanitize user input. However, sometimes we need to convert these slugified paths back into readable strings for various purposes. In this blog, we will explore how to accomplish this task using PHP.

Method 1: Using the str_replace() Function

To convert a slugified file path to a string is by using the str_replace() function. This function replaces all occurrences of a specified substring with another substring in a given string.

<?php
$slugified_path = "this-is-a-slugified-file-path";
$readable_path = str_replace("-", " ", $slugified_path);
echo $readable_path;
?>

Output:

this is a slugified file path

In this example, we define a variable $slugified_path containing the slugified file path. We then use the str_replace() function to replace all hyphens ("-") with spaces (" ") in the slugified path. The resulting string is stored in the $readable_path variable, which is then echoed to the output.

Method 2: Using Regular Expressions (Regex)

Another approach to convert a slugified file path to a string is by using regular expressions. Regular expressions provide a powerful way to search for and manipulate strings based on patterns.

<?php
$slugified_path = "this-is-a-slugified-file-path";
$readable_path = preg_replace('/-/', ' ', $slugified_path);
echo $readable_path;
?>

Output:

this is a slugified file path

In this example, we use the preg_replace() function, which performs a search and replace using a regular expression pattern. The pattern /-/ matches all occurrences of hyphens ("-") in the slugified path, and we replace them with spaces (" "). The resulting string is stored in the $readable_path variable and then echoed to the output.

Conclusion:

In this blog, we have explored two methods to convert a slugified file path to a readable string in PHP. The first method utilizes the str_replace() function, which provides a simple approach by replacing specific substrings. The second method uses regular expressions (preg_replace()), offering more flexibility and power for string manipulation based on patterns.
