Access array returned by a function in php

该法典:

$cnt = mysql_fetch_row(mysql_query("SELECT FOUND_ROWS()"))[0]

给出错误:

Parse error: syntax error, unexpected [ in index.php on line 117

抽样:

$cnt = (mysql_fetch_row(mysql_query("SELECT FOUND_ROWS()")))[0]

该法典:

$cnt = mysql_fetch_row(mysql_query("SELECT FOUND_ROWS()"));
$cnt = $cnt[0];

工作罚款。

这里的情况如何?

最佳回答

它只是一个问题,即<密码>mysql_query--rather, 它以PHP <的方式发挥了辅助作用;5.4 处理 br。 The following willail

function get_array() {
  return array( foo ,  bar );
}

echo get_array()[0];

但是,正如你指出的那样,在试图检索以下要素之前确定结果:

$arr = get_array();
echo $arr[0];
