//利用 explode 函数分割字符串到数组
代码如下:
1 2 3 4 5 6 7 8 9 10 | <?php
$source = "hello1,hello2,hello3,hello4,hello5" ;
$hello = explode (',', $source );
for ( $index =0; $index < count ( $hello ); $index ++)
{
echo $hello [ $index ]; echo "</br>" ;

通过数组实现多条件查询的代码
代码如下:
1 2 3 4 5 6 7 8 9 10 | <?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 ;
