Variable name of array element

Postby ramverma » Sat Sep 12, 2015 10:46 am

Hello All,

Just started to learn and work with PHP, got stuck and couldn't figure out with documentation.

CODE: SELECT ALL
<?php
$nodes = array('server01', 'server02' , 'server03' , 'server04');
$comps = array('CPU', 'Memory', 'Uptime', 'Disk', 'IO-s', 'pgflts');
$file = 'test_file.txt';
foreach ($nodes as $node_each){
foreach ($comps as $comp_each){
$searchfor = $node_each .'|'. $comp_each;
$contents = file_get_contents($file);
$pattern = preg_quote($searchfor, '/');
$pattern = "/^.*$pattern.*\$/m";
if(preg_match_all($pattern, $contents, $matches)){
$line = reset($matches[0]);
$line_arr = (explode('|', $line));
${$nodes.$comps} = $line_arr[2];
echo ${$nodes.$comps};
echo "<br />";
}
else{
echo "No matches found";
}
}
}
// I would like to call all the variables here outside of foreach loop scope as below..
// echo $server01.cpu;
// echo $server02.mem;
?>
please hint or guide me here? If my approach itself is not correct here, please point the same. Thanks!
