filter_input – PHPテストデータ一覧 – テストデータを入れてみました

  • 2016.10.28
  • PHP

PHPのfilter_inputのテストデータを入れて検証を行いました。検証フィルタ、除去フィルタ、フィルタフラグのテストを行いました。
バリデーションを行う際の参考にしてください。

表の見方は、左から、「フィルター」「テストする値」「フィルターの結果」になります。
「フィルタフラグ」がある場合は、フィルターの後にカンマで続けて記載しております。

検証フィルタ

“1”、”true”、”on” および “yes” の場合に TRUE、 それ以外の場合に FALSE を返します。FILTER_NULL_ON_FAILURE が設定されている場合は、 FALSE が返されるのは “0”、”false”、”off”、”no” および “” の場合のみとなります。 boolean 以外の値については NULL を返します。

htmlspecialchars() に ENT_QUOTES を指定してコールするのと同じです。 クォートのエンコードを無効にするには FILTER_FLAG_NO_ENCODE_QUOTES を設定します。 htmlspecialchars() と同様、このフィルタは default_charset に対応しています。 現在の文字セットで無効な文字となるバイトシーケンスが検出されると文字列全体を拒否し、 結果は長さ 0 の文字列となります。 このフィルタをデフォルトのフィルタとして使う場合は、以下の警告を参考にして デフォルトのフラグを 0 に設定しましょう。

htmlspecialchars() に ENT_QUOTES を指定してコールするのと同じです。 クォートのエンコードを無効にするには FILTER_FLAG_NO_ENCODE_QUOTES を設定します。 htmlspecialchars() と同様、このフィルタは default_charset に対応しています。 現在の文字セットで無効な文字となるバイトシーケンスが検出されると文字列全体を拒否し、 結果は長さ 0 の文字列となります。 このフィルタをデフォルトのフィルタとして使う場合は、以下の警告を参考にして デフォルトのフラグを 0 に設定しましょう。
フィルタフラグ： このフラグを指定すると、シングルクォート (‘) およびダブルクォート (“) をエンコードしません。
