我有以下数组$foo
原文链接：https://www.f2er.com/php/133664.htmlarray(10) {
[0] => array(4) {
["merchantId"] => string(5) "12e21"
["programId"] => string(27) "ddd3333"
["networkId"] => int(4)
["clientId"] => int(178)
}
[1] => array(4) {
["merchantId"] => string(5) "112e1"
["programId"] => string(27) "2vfrdbv1&=10&tmfdpid=csss"
["networkId"] => int(4)
["clientId"] => int(178)
}
[2] => array(4) {
["merchantId"] => string(5) "112e1"
["programId"] => string(27) "2vfrdbv1&=10&tmfdpid=csss"
["networkId"] => int(4)
["clientId"] => int(178)
}
我需要一个clientId数组(仅限)
是否可以只访问clientId来创建一个没有循环的id数组？
就像是：
$foo['clientId']; //which doesn't work
