The closest PHP equivalent of the JavaScript decodeURIComponent()
function is the rawurldecode()
function. However, you could also use the PHP urldecode()
function. The difference between the two is in the way they decode literal plus sign (i.e. "+
") present in the URL query string:
urldecode()
will decode+
into a space character;rawurldecode()
(as well as the JavaScriptdecodeURIComponent()
) will not decode the+
sign into any other character.
For example:
decodeURIComponent('+') === '+'; // true
<?php rawurldecode('+') === '+'; // true
<?php urldecode('+') === ' '; // true
Both PHP functions are valid and have their use cases. Therefore, depending on your use case you can choose either one.
Please note that you do not need to explicitly use urldecode()
on $_GET
and $_REQUEST
array elements, as they're automatically decoded by PHP.
