PHP 分割字元串

分割字元串 

//利用 explode 函數分割字元串到數組 

複制代碼代碼如下:

<?php 

$source = "hello1,hello2,hello3,hello4,hello5";//按逗号分離字元串 

$hello = explode(',',$source); 

for($index=0;$index<count($hello);$index++) 

{ 

echo $hello[$index];echo "</br>"; 

} 

?> 

//split函數進行字元分割 

// 分隔符可以是斜線，點，或橫線 

$date = "04/30/1973"; 

list($month, $day, $year) = split ('[/.-]', $date); 

echo "Month: $month; Day: $day; Year: $year<br />\n"; 

通過數組實作多條件查詢的代碼

<?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;
