How to properly URL encode a string in PHP

0 votes
I'm making a search page, where you type a search query and the form is submitted to search.php?query=your query. What PHP function is the best and that I should use for encoding/decoding the search query?

Hello @kartik,

For the URI query use urlencode/urldecode; for anything else use rawurlencode/rawurldecode.

The difference between urlencode and rawurlencode is that

  • urlencode encodes according to application/x-www-form-urlencoded (space is encoded with +) while
  • rawurlencode encodes according to the plain Percent-Encoding (space is encoded with %20).
Hope it helps!!
