Question

我做了以下'foreach'，我需要循环10次然后停止。我不能使用for命令。

<?php
$x=array("Seb","Ginna","Shane","Guy","Jackie","Frances","John","Alec","Jon","Sam","Chris","Paula");
foreach ($x as $value)
{
echo $value . ",";
}
?>

我使用的是这个：

<?php
$theNames = array('Seb', 'Ginna', 'Shane', 'Guy', 'Jackie', 'Frances', 'John', 'Alec', 'Jon', 'Sam', 'Chris', 'Paula');

$toOutput = implode(",", $theNames);

for ($i=0; $i < 10; $i++) { 
print $toOutput."<br/>";
}
?>

以前的代码按照我想要的方式工作但是我需要它在foreach循环中工作

Answer 1

for？我没有看到for。

foreach (range(1, 10) as $i) {
    foreach ($names as $name) {
        echo $name . ', ';
    }
    echo '<br />';
}

$names = array("Seb", "Ginna", "Shane", "Guy", "Jackie", "Frances", "John", "Alec", "Jon", "Sam", "Chris", "Paula");
foreach (range(1, 10) as $i) {
    foreach ($names as $name) {
        echo $name . ', ';
    }
    echo '<br />' . PHP_EOL;
}

现在输出：

Seb, Ginna, Shane, Guy, Jackie, Frances, John, Alec, Jon, Sam, Chris, Paula, <br />
Seb, Ginna, Shane, Guy, Jackie, Frances, John, Alec, Jon, Sam, Chris, Paula, <br />
Seb, Ginna, Shane, Guy, Jackie, Frances, John, Alec, Jon, Sam, Chris, Paula, <br />
Seb, Ginna, Shane, Guy, Jackie, Frances, John, Alec, Jon, Sam, Chris, Paula, <br />
Seb, Ginna, Shane, Guy, Jackie, Frances, John, Alec, Jon, Sam, Chris, Paula, <br />
Seb, Ginna, Shane, Guy, Jackie, Frances, John, Alec, Jon, Sam, Chris, Paula, <br />
Seb, Ginna, Shane, Guy, Jackie, Frances, John, Alec, Jon, Sam, Chris, Paula, <br />
Seb, Ginna, Shane, Guy, Jackie, Frances, John, Alec, Jon, Sam, Chris, Paula, <br />
Seb, Ginna, Shane, Guy, Jackie, Frances, John, Alec, Jon, Sam, Chris, Paula, <br />
Seb, Ginna, Shane, Guy, Jackie, Frances, John, Alec, Jon, Sam, Chris, Paula, <br />

Answer 2

有关。每。它遍历数组中的每个对象。你可以解决这个问题并像for循环一样计算，但你现在应该只使用for。

Answer 3

此代码应该这样做：

<?php

$i = 0;
$x = array("Seb","Ginna","Shane","Guy","Jackie","Frances","John","Alec","Jon","Sam","Joe","Chris","Paula");
foreach ($x as $value)
{
    if ($i++ > 9) break;
    echo $value . ",";
}

Answer 4

您可以使用PHP range()创建一个包含10个项目的数组，然后使用foreach循环，如下所示

  $counter = range(1, 10);
  foreach($counter as $v)
     echo implode(',', $x) . '<br />';

implode() 使用给定的 glue 连接所有数组元素

Answer 5

我想你只想要一个slice of the array。

$theNames = array('Seb', 'Ginna', 'Shane', 'Guy', 'Jackie', 'Frances', 'John', 'Alec', 'Jon', 'Sam', 'Chris', 'Paula');

$names = array_slice($theNames, 0, 10);

print implode(",", $names) . "\n<br>";

Answer 6

试试这个，它打印出你阵列的所有元素：

更新

$x=array("Seb","Ginna","Shane","Guy","Jackie","Frances","John","Alec","Jon","Sam‌","Chris","Paula");
$i=0;
foreach($x as $value){
 if($i<10)
 { 
  echo $value.', ';
  $i++; 
 }
}

Answer 7

$y=array("Seb","Ginna","Shane","Guy","Jackie","Frances","John","Alec","Jon","Sam","Chris","Paula");
for($x=0;$x<=10;$x++)
{
  foreach ($y as $value)
  {
    echo $value . ",";
  }
  echo "<br>";
}

Answer 8

这个怎么样

//start your count at 1
$count = 1;

//start your loop
foreach ($array as $something) {

    //when your count is at 10 "continue" is to go to the end of the loop
    if ($count == 10) {
        continue;  
    }

    //this will add the next integer
    $count++;

    //end your loop
}

如何让Foreach循环重复10次？
