PHP执行JQ - []括号错误：PHP致命错误：无法使用[]进行读取

Question

I have the following command within a PHP script:

shell_exec('cd /home/scripts/scripts; ./total.sh | jq '.hits .hits [] .fields["termListData.terms"] | .[]' | wc -l > /home/data/total.csv');

which gives me: PHP Fatal error: Cannot use [] for reading ...

the command alone from the command line works perfect but not when within the php script. What I am doing wrong?

Answer 1

The issue is that you have single quote in your command execution

you can probably split your command in two

$jq_args = '.hits .hits [] .fields["termListData.terms"] | .[]';
$cmd = 'cd /home/scripts/scripts; ./total.sh | jq '.escapeshellarg($jq_args).' | wc -l > /home/data/total.csv';
shell_exec($cmd);
