Question

我想设置输出限制，但我不知道如何以及在哪里。任何人都可以帮助我吗？

代码（摘录）：

<?php
$row = mysql_fetch_array($result);
if ($row['Price'] == '0.00') {
echo "<TABLE  width='100%'>\n";
echo "<TR><TD id=tblrowsHead2>Item</TD><TD id=tblrowsHead2>Size</TD><TD  
id=tblrowsHead2>Contact</TD></TR>\n";
for ($i = 0; $i < $numofrows; $i++) {
    $row = mysql_fetch_array($result); //get a row from our result set
    if ($i % 2) { //this means if there is a remainder
        echo "<TR bgcolor=\"#E6E6FA\">\n";
    } else { //if there isn't a remainder we will do the else
        echo "<TR bgcolor=\"white\">\n";
    }
    echo "<TD id=Size>" . $row['Item'] . "</TD><TD id=Size>" . $row['Size'] 
. "</TD> 
<TD id=Price>Contact Us</TD>\n";

}
} else {
echo "<TABLE  width='100%'>\n";
echo "<TR><TD id=tblrowsHead2>Item</TD><TD id=tblrowsHead2>Size</TD><TD  
id=tblrowsHead2>Price</TD></TR>\n";
for ($i = 0; $i < $numofrows; $i++) {
    $row = mysql_fetch_array($result); //get a row from our result set
    if ($i % 2) { //this means if there is a remainder
        echo "<TR bgcolor=\"#E6E6FA\">\n";
    } else { //if there isn't a remainder we will do the else
        echo "<TR bgcolor=\"white\">\n";
    }
    echo "<TD id=Size>" . $row['Item'] . "</TD><TD id=Size>" . $row['Size'] 
. "</TD> 
<TD id=Price>$" . $row['Price'] . "</TD>\n";

}
}

//now let's close the table and be done with it
echo "</TABLE>\n";
?>

Answer 1

根据$ max值http://php.net/manual/en/function.array-chunk.php

在新闻项变量“actions”上使用数组块

检查此输出 - ＆gt; print_r（array_chunk（$ actions，$ max））;

Answer 2

这对我来说是最简单的方法：

//Generating the news items
$i=0;

if (is_array($actions)){
   foreach($actions as $item)
if ($i < $max) {
// Build url like : pages/kalendar.php?year=1900&month=01&day=03&id=2&detail=1 
    $ds = $item['date_start'];
$link = $page_link.'?year='.(substr($ds,0,4)).'&amp;month='.(substr($ds,5,2)).'&amp;day='.(substr($ds,8,2)).'&amp;id='.$item['id'].'&amp;detail=1';
$i +=1; 
?>
