php中利用explode()函数分割字符串到数组示例代码

<?php 
$source = "hello1,hello2,hello3,hello4,hello5";//按逗号分离字符串 
$hello = explode(&#39;,&#39;,$source); 

for($index=0;$index<count($hello);$index++) 
{ 
echo $hello[$index];echo "</br>"; 
} 
?>

<?php 
$date = "04/30/1973"; 
list($month, $day, $year) = split (&#39;[/.-]&#39;, $date); 
echo "Month: $month; Day: $day; Year: $year<br />\n"; 
?>

<?php
$keyword="asp php,jsp";
$keyword=str_replace("  "," ",$keyword);
$keyword=str_replace(" ",",",$keyword);
$keyarr=explode(&#39;,&#39;,$keyword); 
for($index=0;$index<count($keyarr);$index++) 
{ 
$whereSql .= " And (arc.title like &#39;%$keyarr[$index]%&#39; Or arc.keywords like &#39;%$keyarr[$index]%&#39;) ";
} 
echo $whereSql;
