## PHP Query Error: \'Unexpected T_ENCAPSED_AND_WHITESPACE\': Why and How to Fix It?

Unexpected T_ENCAPSED_AND_WHITESPACE Error in PHP Query

While executing a SQL query, you may encounter the error "unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING." This error often arises when you attempt to insert a variable or value without properly escaping it.

In this specific case, the error appears in the line:

$sqlupdate1 = "UPDATE table SET commodity_quantity=$qty WHERE user=$rows['user'] ";

The issue lies in the fact that the variable $rows['user'] is not enclosed in single or double quotation marks. This is necessary to ensure that the query interpreter recognizes the variable as a string and not as part of the query structure itself.

Solution:

To resolve this error, simply enclose the variable in single or double quotation marks. Here is the corrected query:

$sqlupdate1 = "UPDATE table SET commodity_quantity=$qty WHERE user='".$rows['user']."' ";

By adding the quotation marks around $rows['user'], you prevent the interpreter from mistaking it for a syntax element and ensure that it is treated as a string value. Running this corrected query should eliminate the "unexpected T_ENCAPSED_AND_WHITESPACE" error and allow the query to execute successfully.
