syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING

This error message is typically encountered when there is a problem with the syntax of a string in PHP. It suggests that there is a unexpected whitespace or other character within a string, and that PHP was expecting a different type of value (such as a variable or a numeric string). The error message typically points to the specific line and character where the problem is located.

It is likely that there is a typo, missing or extra quotes in the string, or a concatenation error.

You may need to check your code and fix any errors, such as adding or removing quotes or concatenation operators, to correct the problem.
