Draw Function and array

Recommended Posts

I am using the line drawing function and want to change the color of the line after each if statement but the line color stays the same after the first if statement. Anybody any ideas.

 

<?php
$im = imageCreateFromJPEG('Ireland_highres10.jpg');
$red = imagecolorallocate($im, 195, 3, 16);
$blue = imagecolorallocate($im, 143, 5, 171);
$yellow = imagecolorallocate($im, 51, 252, 255);
$color1 = imagecolorallocate($im, 255, 25, 55);
imageSetThickness($im, 14);

// BARROW NAVIGATION

// **Credan Head - Carrick-on-Suir**
reset($barrow_array);
$element = key( $barrow_array);
if ($barrow_array[$element] == 0){
$color1 = $blue;
}elseif ($barrow_array[$element] == 1){
$color1 = $red;
}elseif ($barrow_array[$element] == 2){
$color1 = $yellow;
}

imageLine($im, 1617, 2441, 1545, 2409, $color1);
imageLine($im, 1545, 2409, 1493, 2393, $color1);

next($barrow_array);
// Credan Head - New Ross
if ($barrow_array[$element] == 0){
$color1 = $blue;
}elseif ($barrow_array[$element] == 1){
$color1 = $red;
}elseif ($barrow_array[$element] == 2){
$color1 = $yellow;
}
imageLine($im, 1623, 2439, 1605, 2391, $color1);
imageLine($im, 1605, 2391, 1633, 2339, $color1);

// NewRoss - Graiguenamanagh
next($barrow_array);
if ($barrow_array[$element] == 0){
$color1 = $blue;
}elseif ($barrow_array[$element] == 1){
$color1 = $red;
}elseif ($barrow_array[$element] == 2){
$color1 = $yellow;
}
imageLine($im, 1640, 2321, 1657, 2277, $color1);
imageLine($im, 1657, 2277, 1655, 2225, $color1);

imagejpeg($im, 'populated_map.jpg');
imageDestroy($im);
?>
