php中利用explode函数分割字符串到数组_php技巧

分割字符串

//利用 explode 函数分割字符串到数组

$source = "hello1,hello2,hello3,hello4,hello5";//按逗号分离字符串
$hello = explode(',',$source);

for($index=0;$index{
echo $hello[$index];echo "";
}
?>

//split函数进行字符分割
// 分隔符可以是斜线，点，或横线

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

通过数组实现多条件查询的代码

$keyword="asp php,jsp";
$keyword=str_replace(" "," ",$keyword);
$keyword=str_replace(" ",",",$keyword);
$keyarr=explode(',',$keyword);
for($index=0;$index{
$whereSql .= " And (arc.title like '%$keyarr[$index]%' Or arc.keywords like '%$keyarr[$index]%') ";
}
echo $whereSql;
