**Why am I getting the \'T_ENCAPSED_AND_WHITESPACE\' error in my SQL query?**

Unexpected Error: "T_ENCAPSED_AND_WHITESPACE" Encountered

While executing a SQL query, you may encounter the perplexing error: "unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING." This error specifically highlights an issue with the syntax of your query at the line: "UPDATE table SET commodity_quantity=$qty WHERE user=$rows['user'] ."

Root of the Problem

The root cause of this error lies in the improper handling of quotes around the value being set in the "WHERE" clause. When using string values in a SQL query, they must be enclosed in single or double quotes to distinguish them from variable or numeric values. In this case, the user variable '$rows['user']' is not enclosed in quotes.

Solution

To resolve this error, simply enclose the user variable in single or double quotes. Here's the corrected query:

<code class="php">$sqlupdate1 = "UPDATE table SET commodity_quantity=$qty WHERE user='".$rows['user']."' ";</code>

By adding the necessary quotes, the query will now correctly set the value of 'user' to the value stored in the variable '$rows['user']'. This will resolve the "unexpected T_ENCAPSED_AND_WHITESPACE" error and allow your query to execute successfully.
