我退出野生动物园并找到了这个网页:http://www.homeandlearn.co.uk/php/php6p5.html
他们提出了不同风格的数组(下图),他们的输出看起来与我想要的类似。我发现我 能够在foreach中获得名字和姓氏作为单个变量!
$full_name = array( );
$full_name["David"] = "Gilmour";
$full_name["Nick"] = "Mason";
$full_name["Roger"] = "Waters";
$full_name[""] = "";
$full_name["Richard"] = "Wright";
foreach ($full_name as $firstName => $lastName) {
if ($firstName != '') {
$fn = $firstName;
$ln = $lastName;
$sn_display = $firstName . ' ' . $lastName;
$sn_slug = $firstName . $lastName;
echo '| '.$sn_display.' ';
}
}
echo ' |';
然后我意识到如何使用类似于我之前提交的数组语法:
$submissions = array (
array(
'Jim' => 'Jones' ,
),
array(
'Tina' => 'Tim' ,
),
array(
'' => '' ,
),
array(
'Lazer' => 'Lisa' ,
)
);
foreach ($submissions as $full_name) {
foreach ($full_name as $firstName => $lastName) {
if ($firstName != '') {
$fn = $firstName;
$ln = $lastName;
$sn_display = $firstName . ' ' . $lastName;
$sn_slug = $firstName . $lastName;
echo '| '.$sn_display.' ';
}
}
}
echo ' |';
两者都给我有用的输出:
| Jim Jones | Tina Tim | Lazer Lisa |
我仍然很好奇 - 有更优雅的方式吗?
我正在尝试使用这样的数组,这将通过WordPress Gravity Forms提交填充:
$submissions = array (
array( 'fn' => 'Jim' , 'ln' => 'Jones' ),
array( 'fn' => 'Tim' , 'ln' => 'Tomb' ),
array( 'fn' => '' , 'ln' => '' ),
array( 'fn' => 'Lisa' , 'ln' => 'Lazer' )
);
实现了几个目标
使用以下内容,我可以输出数据:
foreach($submissions as $submit) { //break down the array
if ($submit != '') { //check for empties
foreach($submit as $key => $value){ //cycle through each subarray
echo $value. ' '; //get the info - the problem: I cant isolate the values as strings
}
}
}
我的输出没用:
| Jim | Jones | Tim | Tomb | Lisa | Lazer |
特别是因为我想为每个用户激活一个使用$value
的函数 - 而不是每个用户的姓名!
如何在这个循环中将名字和姓氏作为字符串?如果我可以将第一个和最后一个作为字符串,我可以在需要时将它们连接起来,并在我想要的时候在元数据中使用它们。
foreach($submissions as $submit) { //break down the array
if (implode('', $submit) != '') { //check for empties
foreach($submit as $key => $value){ //cycle through each subarray
$fn = $value?Looking for this code?; //I want to make strings!
$ln = $value?Looking for this code?; //One for each value.
$display_name = $fn . ' ' . $ln; // With strings I can make stuff
$name_slug = $fn . $ln;
/* More functions will happen as we cycle through each
submission that has user data until all the user data submissions
have been handled */
}
}
}
答案 0 :(得分:0)
您正在尝试使用$ value [0]获取$ value字符串的第一部分。 试试吧:
$output .= ' | ' . $key . ' - ' . $value;
而不是
回声'| ”。$值[0]。 '';
并在最后回显$ output。
