PHP Pass To Javascript Php Array Associative Array Or Matrix

»»» shrink text ««« ««« enlarge text »»»

OBJECTIVE: given a php array, either numerically indexed or associative, or a matrix combining both (therefore we have three distinct procedures), get its values and rebuild it as a symmetrical javascript valid array or matrix.

INPUTS: an array.  
 
RETURNS: nothing being arranged as a procedure and not as a function; however a function would return a string representing the valid javascript syntax that reproduces in javascript the php data structure. These procedures echo such a string.  
 
Caveats: since in our javascript strings will be represented in the arrays as single quotes sorrounded texts, the procedures need to escape single quotes that may be present in the php data otherwise printing them unescaped would determine a premature closing of the javascript strings.  
The same would apply in case you would use double quotes to sorround javascript strings, yet in such case you'd escape dobule quotes.  
 
It assigns to the output javascript array the arbitrary name genreArray.
