php prompts Parse error: syntax error, unexpected T_ENDWHILE in_PHP tutorial

I encountered Parse error: syntax error, unexpected T_ENDWHILE in www.bKjia.c0m .php file while writing a simple program. Let me analyze the reasons and solutions for you.

Problem:

1. The same code runs normally on some machines, but an error occurs when running on a specific machine.

2. Some pages of the same site display normally (such as ), but when opening some pages, the phpxx_errors.log or page displays the error message "Parse error: syntax error, unexpected T_ENDWHILE in xx.php on line xx”.

Error reason:

This error may be caused by missing a curly brace ("}") when writing the PHP script, but the more common reason is that the short_open_tag value in the php.ini file is Off.

Determines whether the abbreviated form of the PHP code start flag ( ?>) is allowed. If you are using PHP with XML, you can disable this option to facilitate embedded use of . Otherwise, you can also output it through PHP, for example: . If disabled, the full form of the PHP code start flag () must be used.

Note: This directive also affects the abbreviated form =, which is equivalent to echo. Using this abbreviation requires setting short_open_tag to On. It is not recommended to use short tags. The standard method is to use . However, because this short tag has been used for a long time (historical reasons), this feature has been preserved for compatibility with old codes.

Solution:

Set the short_open_tag value in the php.ini file to On.
