PHP class value not accessible after initializing - php

Question

I am trying to turn an input file in the form below into a series of objects that can be manipulated.
arabian_sea_area = {
1926 1927 1931 1932 1933 2029 2030
}
gulf_of_aden_sea_area = {
1925 2024 5285 5286
}
sdf
<?php
$all_areas = array();
if (($handle = fopen("area.txt", "r")) == False)
{
die("failed to open file\n");
}
while (($line = fgets($handle)) !== FALSE)
{
if (ctype_alpha($line[0]))
{
$line= explode(" ",$line);
// echo($line[0]."\n");
$area = $line[0];
$IDs = explode(" ", fgets($handle));
$IDs[0] = ltrim($IDs[0], ' '); // trying to remove tab from first ID
$all_areas[$area] = $IDs;
//array_push($all_areas, $temp);
}
}
//echo("a\n");
print_r($all_areas["arabian_sea_area"]);
//var_dump ($all_areas);
?>
The values print correctly in the commented out debug lines but fail to print anything for the var_dump at the end.
edit: I realize this was unclear, what I was trying to do was create a master "all_areas" array that linked to objects titled the first line (ie. arabian_sea_area etc.) and I could then get at the numerical Ids for each area algorithmically for a later script.

Answer 1

There are many issues with your code:
1-
if (ctype_alpha($line[0]))
{
$line= explode(" ",$line);
//echo($line[0]."\n");
$temp = $line[0];
$temp = new Area;
$temp->filler($line, $handle);
}
you are creating a $temp variable but you forgot to push it to your main array $all_areas. use array_push
2-
var_dump ($arabian_sea_area);
$arabian_sea_area does not exist.
Did you mean to print your main array $all_areas ?
3- Recommendation:
On errors (echo("failed to open file\n");) its recommended to use die("failed to open file\n"); instead of echo. as die will stop the rest of the script from executing.
-- UPDATE --
I edited your code in a way that should work fine:
class Area {
public $area_name;
public $IDs = array();
public function filler($line, $handle) {
$this->area_name = $line[0];
//echo($this->area_name."\n");
$this->IDs = explode(" ", fgets($handle));
//print_r($this->IDs);
}
}
$all_areas = array();
if (($handle = fopen("area.txt", "r")) == False)
{
die("failed to open file\n");
}
while (($line = fgets($handle)) !== FALSE)
{
if (ctype_alpha($line[0]))
{
$line= explode(" ",$line);
// echo($line[0]."\n");
$temp = $line[0];
$temp = new Area;
$temp->filler($line, $handle);
array_push($all_areas, $temp);
}
}
//echo("a\n");
var_dump ($all_areas);
You might wanna update it to remove / filter empty values.
