How to Resolve Encoding Mismatch Issues When URL Decoding in PHP?

URL Decoding in PHP: Encoding Mismatch Issue

When working with URL-encoded strings in PHP, there are occasional hiccups related to encoding conflicts. One such case arises when decoding a URL string that has both URL encoding and UTF-8 encoding.

Consider the following URL string:

Ant%C3%B4nio+Carlos+Jobim

This string is intended to decode to the following:

Antônio Carlos Jobim

However, when we use the urldecode() function, we obtain:

Antônio Carlos Jobim

This discrepancy occurs because the original string is not only URL-encoded but also UTF-8 encoded. To resolve this issue, we need to employ the utf8_decode() function, which converts UTF-8 encoding to Unicode.

The following code snippet demonstrates the solution:

<code class="php">echo utf8_decode(urldecode("Ant%C3%B4nio+Carlos+Jobim"));</code>

This will successfully output the expected string:

Antônio Carlos Jobim
