I have something like this:
host1 | port1
host2 | port2
host3 | port3
host4 | port4
Now, I need to insert pairs into an array so I can use them in a loop:
I tried to loop through one value of an array
$hosts = array('host1','host2','host3');
foreach ($hosts as $host) {
echo $host;
}
How do I add pairs to an array so I can call say host it outputs both host and port?
You could create your array like this which creates named keys for each host:
$hosts = array(
'host1' => 'port1',
'host2' => 'port2',
'host3' => 'port3'
);
(Example #1 here: http://www.php.net/manual/en/function.array.php)
You can then iterate through the array like so to grab the array key and value:
foreach($hosts as $host => $port){
echo 'This is the ' . $host;
echo 'This is the ' . $port;
}
(http://www.php.net/manual/en/control-structures.foreach.php)
$hosts = array('host1' => array('port1a', 'port1b')); You can then access the data in that array like so: echo $hosts['host1'][0]; // Will echo 'port1a'You can use multidimensional array. Like this
$data= array
(
array("host1","yourport1"),
array("host2","yourport2"),
array("host3","yourport3"),
);
and can access like this
echo "Host: ". $data[0][0]." Port: ".$data[0][1];
You could add arrays to the array, so you get an multidimensional array:
$hosts = array(array('host1', 'port1'), array('host2', 'port2'));
Fast way:
// also You can define it as string directly, but I think You have a file :)
foreach(explode(PHP_EOL,file_get_contents('myIP.txt')) as $line){
$hosts[explode(' | ',$line)[0]] = explode(' | ',$line)[1];
}
var_dump($hosts);
// You will have pairs host1 => port1, host2=>port2, etc
There's on more way with array_walk, but I'm too lazy to read docs about array_walk. Hope this solution will completly solve Your task
$myhosts = "host1 | port1 \r\n host2 | port2 \r\n"; and replace file_get_contents('myIP.txt') with $myhosts. It'll work. Cheers
