Arrays Outside A Function Need to have arrays available to all functions.

[sonesay 7]

I've got a bunch of arrays that i want to use for more then 1 function. when i declear the arrays outside a function i cant use it in a function.

This code was originally written in javascript by another person but since I plan to use it and extend it with php I had to change it from javascript to php code. In the javascript code the arrays were decleared outside the functions with 'var arrayname' I read somewhere that declearing javascript variables with 'var' gives it global access. Any ideas on how I can go about declearing 1 set of these arrays to be used by as many functions as I need without copying them into every function?


below is current state with arrays inside GetHP();

function GetHP($raceIndex, $mjobIndex, $sjobIndex, $mainLevel, $subLevel) {			// Hume                D  D  D  D  D  D  D  D  D	$raceGrades[0] = array(4, 4, 4, 4, 4, 4, 4, 4, 4);	// Elvaan              C  E  B  E  C  F  F  B  D	$raceGrades[1] = array(3, 5, 2, 5, 3, 6, 6, 2, 4);	// Taru                G  A  F  D  E  C  A  E  D	$raceGrades[2] = array(7, 1, 6, 4, 5, 3, 1, 5, 4);	// Mithra              D  D  E  A  E  B  D  E  F	$raceGrades[3] = array(4, 4, 5, 1, 5, 2, 4, 5, 6);	// Galka               A  G  C  D  A  E  E  D  F	$raceGrades[4] = array(1, 7, 3, 4, 1, 5, 5, 4, 6);			$jobGrades[0]  = array(4, 0, 4, 4, 4, 6, 4, 4, 2);	// BST                 C  x  D  C  D  F  E  E  A	$jobGrades[1]  = array(3, 0, 4, 3, 4, 6, 5, 5, 1);	// BLM                 F  B  F  C  F  C  A  E  D	$jobGrades[2]  = array(6, 2, 6, 3, 6, 3, 1, 5, 4);	// BLU                 D  D  E  E  E  E  E  E  E	$jobGrades[3]  = array(4, 4, 5, 5, 5, 5, 5, 5, 5);	// COR                 D  x  E  C  E  C  C  E  E	$jobGrades[4]  = array(4, 0, 5, 3, 5, 3, 3, 5, 5);	// DRK                 C  F  A  C  C  D  C  G  G	$jobGrades[5]  = array(3, 6, 1, 3, 3, 4, 3, 7, 7);	// DRG                 C  x  B  D  C  D  F  E  C	$jobGrades[6]  = array(3, 0, 2, 4, 3, 4, 6, 5, 3);	// MNK                 A  x  C  B  A  F  G  D  E	$jobGrades[7]  = array(1, 0, 3, 2, 1, 6, 7, 4, 5);	// NIN                 D  x  C  B  C  B  D  G  F	$jobGrades[8]  = array(4, 0, 3, 2, 3, 2, 4, 7, 6);	// PLD                 C  F  B  E  A  G  G  C  C	$jobGrades[9]  = array(3, 6, 2, 5, 1, 7, 7, 3, 3);	// PUP                 D  x  E  B  D  C  E  F  C	$jobGrades[10] = array(4, 0, 5, 2, 4, 3, 5, 6, 3);	// RNG                 E  x  E  D  D  A  E  D  E	$jobGrades[11] = array(5, 0, 5, 4, 4, 1, 5, 4, 5);	// RDM                 D  D  D  D  E  E  C  C  D	$jobGrades[12] = array(4, 4, 4, 4, 5, 5, 3, 3, 4);	// SAM                 B  x  C  C  C  D  E  E  D	$jobGrades[13] = array(2, 0, 3, 3, 3, 4, 5, 5, 4);	// SMN                 G  A  F  E  F  D  B  B  B	$jobGrades[14] = array(7, 1, 6, 5, 6, 4, 2, 2, 2);	// THF                 D  x  D  A  D  B  C  G  G	$jobGrades[15] = array(4, 0, 4, 1, 4, 2, 3, 7, 7);	// WAR                 B  x  A  C  D  C  F  F  E	$jobGrades[16] = array(2, 0, 1, 3, 4, 3, 6, 6, 5);	// WHM                 E  C  D  F  D  E  E  A  C	$jobGrades[17] = array(5, 3, 4, 6, 4, 5, 5, 1, 3);			$hpScale[0] = array( 0, 0, 0, 0);	$hpScale[1] = array(19, 9, 1, 3);	$hpScale[2] = array(17, 8, 1, 3);	$hpScale[3] = array(16, 7, 1, 3);	$hpScale[4] = array(14, 6, 0, 3);	$hpScale[5] = array(13, 5, 0, 2);	$hpScale[6] = array(11, 4, 0, 2);	$hpScale[7] = array(10, 3, 0, 2);			$mpScale[0] = array( 0, 0,   0);	$mpScale[1] = array(16, 6,   4);	$mpScale[2] = array(14, 5,   4);	$mpScale[3] = array(12, 4,   4);	$mpScale[4] = array(10, 3,   4);	$mpScale[5] = array( 8, 2,   3);	$mpScale[6] = array( 6, 1,   2);	$mpScale[7] = array( 4, 0.5, 1);		$statScale[0] = array(0,    0,    0);	$statScale[1] = array(5, 0.50, 0.10);	$statScale[2] = array(4, 0.45, 0.20);	$statScale[3] = array(4, 0.40, 0.25);	$statScale[4] = array(3, 0.35, 0.35);	$statScale[5] = array(3, 0.30, 0.35);	$statScale[6] = array(2, 0.25, 0.40);	$statScale[7] = array(2, 0.20, 0.40);				$baseValueColumn = 0;	$scaleTo60Column = 1;	$scaleOver60Column = 3;	$scaleOver30Column = 2;	$hpIndex = 0;		  // Set up temp variables	$mainLevelE;	$mainLevelX;	$mainLevelXXX;	$mainLevelLX;	$mainLevelL;	$subLevel;	$subLevelX;	  	$mainLevelUpTo60;	$mainLevelOver10;	$mainLevelOver30;	$mainLevelOver60;	$mainLevelOver50andUnder60;	$subLevelOver10;	$subLevelOver30;		$raceHP;	$jobHP;	$sJobHP;	$bonusHP = 0;		$grade;// Get level breaks for changes in the stat formulas    //#####################################  // Primary HP levels    // First scale up to 60  $mainLevelUpTo60 = $mainLevel - 1;

If I cut and paste the arrays in the above code outside the GetHP(); the function stops to work correctly.

[jlhaslip 4]

declare them as global in the function the arrays are used in

[truefusion 3]

JavaScript and PHP both handle things differently. In JavaScript, variables outside a function can be used within a function and vice versa. JavaScript also doesn't need to be in a specfic order in order to pick other functions up, where in PHP everything is read from top to bottom. Like jlhaslip said, the variables that hold these arrays, declare them as a global. To do so, at the begining of the function, type in global then the variables afterwards, for example:

function GetHP($raceIndex, $mjobIndex, $sjobIndex, $mainLevel, $subLevel) {global $arr1, $arr2;//rest of the coding...}

Thanks guys it works like a charm.
