PHPStorm has been a little annoying with showing all these code issues. I took some time to analyse most of them and fix whichever were easy to fix. This kind of change should improve future maintenance as developers do not need to wonder what a line of code does. Code that has no impact on functionality should be removed. * Remove redundant variables * Invert condition for better clarity * Remove some of the redundant casts * Replace switch with an if * Fix foreach variable * Remove redundant variable concat * Remove redundant concats * Replace for loop with str_repeat * Remove always true param * Turn property $position into local var * Turn Pdf properties into local vars * Remove unused properties in Pdf * Change ternary into condition * Remove redundant assignments They are immediately overwritten with a different value. * Redundant array append * Collapse if statements into assignments * Use boolean constants instead of variables * Remove unneeded parameter * Remove null-coalesce * Unnecessary assignment * Remove redundant isset * Remove readOnly flag for InsertEdit fields * Remove function_exists and $mode var * Remove duplicate condition * Remove redundant elseif * Remove redundant isset * Use hasBodyParam() * Simplify isRoutesCacheFileValid() Psalm complains but is wrong. https://github.com/phpmyadmin/phpmyadmin/pull/18063 --------- Signed-off-by: Kamil Tekiela <tekiela246@gmail.com>
