分割字符串 //利用 explode 函数分割字符串到数组
复制代码 代码如下:
<?php
$source = "hello1,hello2,hello3,hello4,hello5";//按逗号分离字符串
$hello = explode(",",$source); for($index=0;$index<count($hello);$index++)
{
echo $hello[$index];echo "</br>";
}
?>

//split函数进行字符分割
// 分隔符可以是斜线，点，或横线
复制代码 代码如下:
<?php
$date = "04/30/1973";
list($month, $day, $year) = split ("[/.-]", $date);
echo "Month: $month; Day: $day; Year: $year<br />";
?>
通过数组实现多条件查询的代码复制代码 代码如下:
<?php
$keyword="asp php,jsp";
$keyword=str_replace("  "," ",$keyword);
$keyword=str_replace(" ",",",$keyword);
$keyarr=explode(",",$keyword);
for($index=0;$index<count($keyarr);$index++)
{
$whereSql .= " And (arc.title like "%$keyarr[$index]%" Or arc.keywords like "%$keyarr[$index]%") ";
}
echo $whereSql;
