php 字符串分割輸出

分割字符串
//利用 explode 函數分割字符串到數組
複製代碼代碼以下:
<?php
$source = "hello1,hello2,hello3,hello4,hello5";//按逗號分離字符串
$hello = explode(',',$source);
for($index=0;$index<count($hello);$index++)
{
echo $hello[$index];echo "</br>";
}
?>
//split函數進行字符分割
// 分隔符能夠是斜線，點，或橫線
複製代碼代碼以下:
<?php
$date = "04/30/1973";
list($month, $day, $year) = split ('[/.-]', $date);
echo "Month: $month; Day: $day; Year: $year<br />\n";
?>
經過數組實現多條件查詢的代碼
複製代碼代碼以下:
<?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;
