What best practices should the user follow to avoid similar errors in PHP variable assignment?

When assigning variables in PHP, it's important to use the correct syntax and pay attention to the order of operations. To avoid errors like the one mentioned, always ensure that the variable is on the left side of the assignment operator (=) and the value or expression is on the right side. Additionally, double-check the variable names for any typos or inconsistencies.

// Incorrect variable assignment
$var1 = $var2 + 5; // This will result in an error if $var2 is not previously defined

// Correct variable assignment
$var2 = 10;
$var1 = $var2 + 5; // This will assign the value 15 to $var1
