■背景

・phpを7.* から 8.* にアップデートしたら、urlencode()関数がエラーになったので、自作関数を作成し、一括置換して対応。

■エラーメッセージ

・Deprecated: urldecode(): Passing null to parameter #1 ($string) of type string is deprecated in C:************* .php on line 9999

■ 対応関数

function.php


// === PHP 8 対応 urlencode()
function UrlEncode_Val_Check($data)
{
    if ($data != "") {
        $data_encode = urlencode($data);
        return $data_encode;
    } else {
        return $data = "";
    }
}

■ 使い方

urlencodeをUrlEncode_Val_Checkに置換するだけ

index.php


    echo '<tr style="background: green;" data-href="./five.php?select_day=' . UrlEncode_Val_Check($select_day) .
                                            '&souko_code=' . UrlEncode_Val_Check($select_souko_code) .
                                            '&unsou_code=' . UrlEncode_Val_Check($select_unsou_code) .
                                            '&unsou_name=' . UrlEncode_Val_Check($Picking_VAL['Unsou_name']) .
                                            '&shipping_moto=' . UrlEncode_Val_Check($Picking_VAL['shipping_moto']) .
                                            '&shipping_moto_name=' . UrlEncode_Val_Check($Picking_VAL['shipping_moto_name']) .

                                            '&Shouhin_name=' . UrlEncode_Val_Check($Picking_VAL['Shouhin_name']) .
                                            '&Shouhin_num=' . UrlEncode_Val_Check($Picking_VAL['Shouhin_num']) .
                                            '&Tokuisaki=' . UrlEncode_Val_Check($Tokuisaki_name) .
                                            '&tana_num=' . UrlEncode_Val_Check($Picking_VAL['Tana_num']) .
                                            '&case_num=' . UrlEncode_Val_Check($Case_num_View) .

                                            '&shouhin_jan=' . UrlEncode_Val_Check($shouhin_JAN) .
                                            '&tokki_zikou=' . $Picking_VAL['tokki_zikou'] .
                                            '&Denpyou_SEQ=' . UrlEncode_Val_Check($Picking_VAL['Denpyou_SEQ']) . // 伝票 SEQ
                                            '&now_sql=' . $encoded_sql_one_tokki . '">';
