Question

In crontab, I have added a php script name, running this script from CLI SAPI mode, so no max_execution_time problem.

I can pass several parameters using spaces.

system('/path/of/your/script.php param1 param2 > scriptlog.txt &')

But I need to pass an array as parameter is shell script and breakdown the array.

for example,

system('/path/of/your/script.php array > scriptlog.txt &')

When you cast system in your app, you must implode your parameters
Just pass arguments successively like

system('/path/of/your/script.php param[0] param[1] > scriptlog.txt &')

This would look like

system('/path/of/your/script.php '.implode(" ",$params).' > scriptlog.txt &')

If you’re having quotes, you can take a look at escapeshellarg

system('/path/of/your/script.php '.implode(" ",array_map("escapeshellarg",$params)).' > scriptlog.txt &')

Then in your script.php, catch parameters with

$args = $argv;
array_shift($args); //Because $args[0] is 'script.php'

If you’re catching > scriptlog.txt & in your script.php, use this instead:

$args = $argv;
if (false !== ($pos = array_search(">",$args))) {
    $args = array_slice($args,1,$pos-1);
} else {
    array_shift($args);
}

Note that this works only if your array is non-associative.
You’ll need to write another function to retrieve associative params
