Php 在另一个值的顶部回显值
我认为这很简单,但我似乎没有完成。我想做的是将从FOREACH循环中得到的值显示在其他回显值的顶部Php 在另一个值的顶部回显值,php,Php,我认为这很简单,但我似乎没有完成。我想做的是将从FOREACH循环中得到的值显示在其他回显值的顶部 function writeMsg($total) { echo $total. "< This must display First"; } foreach ($array as $value) { echo $value["Price"]."<br>"; $total = $value["Total"]; } writeMsg($total); 以前 ec
function writeMsg($total) {
echo $total. "< This must display First";
}
foreach ($array as $value) {
echo $value["Price"]."<br>";
$total = $value["Total"];
}
writeMsg($total);
以前
echo $value["Price"]."<br>";
echo$value[“Price”]。“
”;
我希望你们能理解我的问题 我不完全确定你想得到什么,但我的猜测是:
function writeMsg($total) {
echo $total. "< This must display First";
}
$total = 0;
$prices = array();
foreach ($array as $value){
$prices [] = $value["Price"];
$total += $value["Total"];
}
echo implode("<br>", $prices);
echo "<br>";
writeMsg($total);
函数writeMsg($total){
echo$total.“<必须首先显示”;
}
$total=0;
$prices=array();
foreach($array作为$value){
$prices[]=$value[“Price”];
$total+=$value[“total”];
}
回声内爆(“
”,美元价格);
回声“
”;
书面形式(共计);
您可以使用:
ob_start();//现在回显的所有内容都已缓冲
foreach($array作为$value){
echo$value[“价格”]。“
”;
$total=$value[“total”];
}
$all_the_echoos=ob_get_clean();//捕获缓冲区到变量
writeMsg(总计);//呼应总
echo$all__回音;//回显捕获的缓冲区
请注意,可能有一个更干净的解决方案,但除非你更新你的问题,否则我只能猜测你想要实现什么。我认为你想要的是这样的。在foreach循环中,您希望积累数据,并在以后将其回显出来。在那里,您可以选择首先回显什么
function writeMsg($total) {
echo $total. "< This must display First";
}
$total = 0;
$prices = '';
foreach ($array as $value){
// concatenate all prices into a single string. echo this later (after echo of totals)
$prices .= $value["Price"]."<br>";
// sum up total of all values
$total += $value["Total"];
}
writeMsg($total);
echo $prices;
函数writeMsg($total){
echo$total.“<必须首先显示”;
}
$total=0;
$价格='';
foreach($array作为$value){
//将所有价格连接成一个字符串。稍后回显(在回显总计之后)
$prices.=$value[“Price”]。“
”;
//所有值的总和
$total+=$value[“total”];
}
书面形式(共计);
回声美元价格;
您在foreach中回音。如果你不想在其他输出之前显示该输出,请不要在foreach中回音。不,你的问题不清楚。所以你想回音$total,对吗?谢谢,伙计,这正是我要找的。
ob_start(); // everything echo'ed now is buffered
foreach ($array as $value){
echo $value["Price"]."<br>";
$total = $value["Total"];
}
$all_the_echoes = ob_get_clean(); // capture buffer to variable
writeMsg($total); // echoes the total
echo $all_the_echoes; // echoes the captured buffer
function writeMsg($total) {
echo $total. "< This must display First";
}
$total = 0;
$prices = '';
foreach ($array as $value){
// concatenate all prices into a single string. echo this later (after echo of totals)
$prices .= $value["Price"]."<br>";
// sum up total of all values
$total += $value["Total"];
}
writeMsg($total);
echo $prices;
