creating an array with value as empty string

[supernova.surfer]

Hello

      i need help making an array with these parameters but i dont know the syntax to use

$x = 30

 

i need $x to be the 30'th value in the array called lets say $array1 , but i need the first 29 values to be empty strings like " " .

so basically everytime i have different values for $x the array should get constructed accordingly with $x-1 number of " " values .

would appreciate help with this construct ..thanks

Sounds pretty inefficient to fill up an array with empty values, what are you using it for? There should be a better solution.

 

This will do it nonetheless:

 

<?php
$x = 30;
$array1 = array_fill(1, $x - 1, '');
$array1[$x] = $x;
echo '<pre>';
print_r($array1);
echo '</pre>';
?>

 

Output:

Array
(
    [1] => 
    [2] => 
    [3] => 
    [4] => 
    [5] => 
    [6] => 
    [7] => 
    [8] => 
    [9] => 
    [10] => 
    [11] => 
    [12] => 
    [13] => 
    [14] => 
    [15] => 
    [16] => 
    [17] => 
    [18] => 
    [19] => 
    [20] => 
    [21] => 
    [22] => 
    [23] => 
    [24] => 
    [25] => 
    [26] => 
    [27] => 
    [28] => 
    [29] => 
    [30] => 30

Hello ,

      Thanks for the reply ... i'm planning to use jpgraph for a application the following is example code

include ("../jpgraph.php");

include ("../jpgraph_scatter.php");

 

$datay = array(30,40,50);

 

$graph = new Graph(300,200,"auto");

$graph->SetScale("textlin");

 

$graph->SetShadow();

$graph->img->SetMargin(40,40,40,40);       

 

$graph->title->Set("Simple mpuls plot");

$graph->title->SetFont(FF_FONT1,FS_BOLD);

 

$sp1 = new ScatterPlot($datay);

$sp1->mark->SetType(MARK_SQUARE);

$sp1->SetImpuls();

 

$graph->Add($sp1);

$graph->Stroke()

 

i need only 3 values on the x-axis ..but if i use the above  ...the values of 30,40,50 (y-scale) ...will be plotted at positions 1,2 and 3

i need them to be plotted at notch 30,40,50 Respectively ...i'll try and be as clear as possible..i hope i am. If i add 30 empty values in the array then my "bar" on my bar plot gets plotted like i want on the 30'th point on the x-scale
