php - base_convert numbers map to letters -


how can use base_convert map numbers letters?

for example 123456 become abcdef. number 123321 become abccba

i have unique number, needs keep it's uniqueness in form of string of letters. way this?

base_convert() converting numbers between different number systems. hex bin.

for task strtr():

$original = '13421'; $replaced = strtr($original, '12345', 'abcde'); echo $replaced; // output: acdba

as see strtr works char-wise translator. if char out of $from string found in input string, translated char @ same position of $to string. however, it's better explained code example above :)

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
