【问题描述】:
我创建了一个数组,其中一个是 php 用来显示从 sqlite3 检索到的记录中的字段的字符串。
我的问题是......它没有。
数组已定义,“1”为第一个数据库字段,“2”为第二个数据库字段:
编辑:我已将问题重新定义为脚本,以便您可以看到整个事情:
//If I have an array (simulating a record retrieved from database):
$record = array(
name => 'Joe',
comments => 'Good Bloke',
);
//then I define an array to reference it:
$fields = array(
1 => array(
'db_index' => 'name',
'db_type' => 'TEXT',
'display' => '$record["name"]',
'form_label' => 'Name',
),
2 => array(
'db_index' => 'comments',
'db_type' => 'TEXT',
'display' => '$record["comments"]',
'form_label' => 'Comments',
),
);
//If I use the lines:
print "expected output:\n";
print " Name = " . $record["name"] ."\n";
print " Comments = " . $record["comments"] ."\n";
//I display the results from the $record array correctly.
//However if I try & use the fields array with something like:
Print "Output using Array values\n";
foreach($GLOBALS["fields"] as $field)
{
$label = $field['form_label'];
$it = $field['display'];
$line = "\"$label = \" . $it .\"\n\"";
print $line;
}
输出:
Expected output:
Name = Joe
Comments = Good Bloke
Output using Array values:
Name = $record["name"]
Comments = $record["comments"]
【问题讨论】:
-
是的,“echo”也可以用来代替“print”,但不会改变输出。
-
$record["name"] 有一些值,否则将按原样打印?
-
不太明白你想问什么。
