Commonly, such loops are intended to perform an action only on their first iteration (for example, get the first element of an array). The inspection does not report foreach loops with a key or value used inside the loop body. Reports the loop statements whose bodies will execute at most once. Reports the variables in return statements that are always null. Reports the conditions inside logical binary expressions that are covered by subsequent conditions and are therefore redundant. Reports the conditions that are already covered by earlier conditions and thus have no effect as well as the variables that are always true (or always false) when reached.Ĭondition inside logical expression checked by subsequent condition The most common source of such problems is modifying an array passed via a parameter: if an array is passed by value, the change will not be visible outside the function.Ĭondition always evaluates to 'true/false'
#IF LOOP ISSET PHP CODE#
Reports the array write access expressions that are not used in code afterwards. Reports the 'switch' statements with duplicated common parts.
Functions with such a return type are not expected to return any value and must prevent the rest of the script execution by either calling die(), exit(), and so on, or throwing an exception.
Reports the functions with the never return type hint that may return some value.
Reports the if statements with duplicated common parts. Such usages may unwillingly overwrite an already defined value and cause latent bugs. Reports the keys and values in foreach loops that are assigned a non-primitive value before the foreach loop and are accessed after it. 'foreach' variable overwrites already defined variable
