Hello; I am using MAMP on MacOS Sequoia and am working on a project on localhost that writes to files from user input. This is intended for private use without any outside input. But I am trying to make revisions to code to correct issues that are cropping up: Here are the complaints: <b>Warning</b>: Undefined array key "NE-date" in <b>/Applications/MAMP/htdocs/newJournal/php/journalProc.php</b> on line <b>131</b><br /> <br /> <b>Deprecated</b>: explode(): Passing null to parameter #2 ($string) of type string is deprecated in <b>/Applications/MAMP/htdocs/newJournal/php/journalProc.php</b> on line <b>131</b><br /> <br /> <b>Warning</b>: Undefined array key 1 in <b>/Applications/MAMP/htdocs/newJournal/php/journalProc.php</b> on line <b>133</b><br /> <br /> <b>Warning</b>: Undefined array key "" in <b>/Applications/MAMP/htdocs/newJournal/php/journalProc.php</b> on line <b>133</b><br /> <br /> <b>Warning</b>: Undefined array key "started" in <b>/Applications/MAMP/htdocs/newJournal/php/journalProc.php</b> on line <b>54</b><br /> <br /> <b>Warning</b>: Trying to access array offset on value of type null in <b>/Applications/MAMP/htdocs/newJournal/index.php</b> on line <b>43</b><br /> You will see in the first line of the warnings: NE-date. I have changed that to NE_date. But several tries have produced the same result. Is there some php cache that is not being cleared? I have a basic setup with Fetch as the FTP client and BBEdit as my text editor. I use an FTP client on local host because I want copies of placed files and not the files themselves and Mac leaves finder related files in directories it is used to read. With and FTP client that does not happen. Here is a snip of the code that is generating the first 4 warnings file_put_contents('test.txt', 'This date submission: '.$_a['NE_date']); // line 131 $_parts = explode(' ', $_a['NE_date']); // line 131 $_dirName = self::$_archDir.'/journal_'.$_parts[0]; // line 133 $_fileName = $_dirName.'/mon_'.self::$_monTranslater[$_parts[1]].'.js'; // 133 This is async submission Thank you for time and attention JK
