How to Convert Encoded Characters to Normal Text in PHP?

Converting Encoded Characters to Normal Text

In certain situations, you may encounter strange characters like ë, Ã, ì, ù, à displaying instead of normal text. This issue can arise when UTF-8 encoded characters are present in your content.

The Cause:

When UTF-8 encoded characters are stored in a database or rendered on a web page that is not configured to handle UTF-8, these characters can appear as strange symbols. This occurs because the encoding of the characters is not recognized, leading to their incorrect display.

The Solution:

To resolve this issue, you need to convert the UTF-8 encoded characters to normal ISO-8859-1 characters. This can be achieved using the utf8_decode() function. By applying this function, the encoded characters will be decoded into their corresponding character representations.

Example:

<code class="php">$encodedText = "ë, Ã, ì, ù, à ";
$decodedText = utf8_decode($encodedText);

echo $decodedText; // Outputs: à, á, ì, í, à</code>
