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 . 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.
