It is important to note that sys_getloadavg() does not return a percentage, and the numbers that it returns are completely meaningless if you do not know the number of CPU cores. To get the number as a percentage you need to divide the value by the number of CPU cores in the system. (eg: if the value is 0.5 and you have two cores, then you are using 25% of the CPU on average). Here is a simple function to get the values as a percent:

<?php
function percentloadavg(){
    $cpu_count = 1;
    if(is_file('/proc/cpuinfo')) {
        $cpuinfo = file_get_contents('/proc/cpuinfo');
        preg_match_all('/^processor/m', $cpuinfo, $matches);
        $cpu_count = count($matches[0]);
    }

    $sys_getloadavg = sys_getloadavg();
    $sys_getloadavg[0] = $sys_getloadavg[0] / $cpu_count;
    $sys_getloadavg[1] = $sys_getloadavg[1] / $cpu_count;
    $sys_getloadavg[2] = $sys_getloadavg[2] / $cpu_count;

    return $sys_getloadavg;
}
?>

xxxxxxxxxx

<?php

function percentloadavg(){

    $cpu_count = 1;

    if(is_file('/proc/cpuinfo')) {

        $cpuinfo = file_get_contents('/proc/cpuinfo');

        preg_match_all('/^processor/m', $cpuinfo, $matches);

        $cpu_count = count($matches[0]);

    $sys_getloadavg = sys_getloadavg();

    $sys_getloadavg[0] = $sys_getloadavg[0] / $cpu_count;

    $sys_getloadavg[1] = $sys_getloadavg[1] / $cpu_count;

    $sys_getloadavg[2] = $sys_getloadavg[2] / $cpu_count;

    return $sys_getloadavg;

?>

Use this:
<?php
$loads=sys_getloadavg();
$core_nums=trim(shell_exec("grep -P '^physical id' /proc/cpuinfo|wc -l"));
$load=$loads[0]/$core_nums;
echo $load;
?>
