循环语句
for
<?php
for($i=0;$i<99999;$i++){
echo "<br>$i.hello beijing!";
}
?>
|
while
<?php
$a = 0;
while ($a<100){
echo "<br>$a.hello qingdao!";
$a = $a+1;
}
?>
|
do while
<?php
$s = 1;
do{
echo "<br>$s.hello jinan!";
$s = $s+1;
}while($s<100);
?>
|
foreach
foreach 循环只适用于数组，并用于遍历数组中的每个键/值对。
<?php
$colors = array("red","green","blue","yellow");
foreach ($colors as $value) {
echo "$value <br>";
}
?>
|
<pre name="code" class="php"><?php
$arr = array("1"=>"111","2"=>"222","3"=>"333");
foreach($arr as $key=>$value)
{
echo $key."=>".$value."\n";
}
?>
结果如下：
1=>111
2=>222
3=>333
