PHP needs to end the instruction with a semicolon after each statement.An end tag in a PHP code implies a semicolon; the last line in a PHP snippet can end without a semicolon.If there are new rows later, the end tag of the snippet contains the end of the line.The end tag of the PHP snippet at the end of the file can be omitted, and in some cases it would be better to omit it when using include or require-avoid unnecessary whitespace characters.PHP Manual-La

If redim () is used to declare an array, the corresponding declaration is automatically inserted in the code. However, the best way is to insert the dim statement into the array first, because to declare the Array Using redim, You need to upgrade the tool to infer the correct declaration. Using redim also produces inconvenient code, because the array is declared in
