As this is a sniff looking for certain functional code patterns, the sniff should disregard whitespace and comments when looking for the relevant tokens to determine whether the code under scan contains the code pattern the sniff is looking for. The sniff, however, does not do this correctly (in multiple places). This commit fixes just one of these issues, as reported in 325. For this particular issue, the `$startPtr` for the `findNext()` is incremented for each `while` loop, but the initial `$startPtr` was also incremented, which meant that if there was no whitespace after an equals sign, the first relevant token was being skipped over. Fixed now. Includes tests. Fixes 325

The sniff, however, does not do this correctly (in multiple places). This commit fixes the same issue as fixed in the previous commit, but now specifically for the part in the code where it is checking that a `$var = $var + 1;` like statement only has one variable in the code comprising the value being assigned. Same as before, the `$startPtr` for the `findNext()` is incremented for each `while` loop, but the initial `$startPtr` was also incremented, which meant that if there was no whitespace after an equals sign, the first relevant token was being skipped over.

Description
As the Squiz/IncrementDecrementUsage sniff is looking for certain functional code patterns, the sniff should disregard whitespace and comments when looking for the relevant tokens to determine whether the code under scan contains the code pattern the sniff is looking for.
The sniff, however, does not do this correctly (in multiple places).
Squiz/IncrementDecrementUsage: bug fix - code without whitespace [1]
This commit fixes just one of these issues, as reported in #325.
For this particular issue, the
$startPtrfor thefindNext()is incremented for eachwhileloop, but the initial$startPtrwas also incremented, which meant that if there was no whitespace after an equals sign, the first relevant token was being skipped over.Fixed now.
Includes tests.
Squiz/IncrementDecrementUsage: bug fix - code without whitespace [2]
This commit fixes the same issue as fixed in the previous commit, but now specifically for the part in the code where it is checking that a
$var = $var + 1;like statement only has one variable in the code comprising the value being assigned.Same as before, the
$startPtrfor thefindNext()is incremented for eachwhileloop, but the initial$startPtrwas also incremented, which meant that if there was no whitespace after an equals sign, the first relevant token was being skipped over.Fixed now.
Includes tests.
Squiz/IncrementDecrementUsage: bug fix - comments between variable and equal sign
This commit fixes another one of these issues.
In this case, if there was a comment between the
$varand the subsequent equal sign, the sniff would incorrectly disregard the assignment as one which should be examined.Fixed now.
Includes tests.
Squiz/IncrementDecrementUsage: bug fix - comments in value being assigned
This commit fixes one more of these issues.
In this case, if there was a comment anywhere in the value being assigned, the sniff would incorrectly disregard the assignment as one which should be examined.
Fixed now.
Includes tests.
