字符串與PHP中的子字符串比較？

Question

字符串目前陣列ATA Report of 7th Apr 2014, ATA Report of 17th Apr 2014, ATA Report of 27th Apr 2014

我有子字符串中7th Apr 2014

我如何才能找到ATA Report of 7th Apr 2014位置

我甲肝像這樣使用，但不是爲我工作

$date = "7th Apr 2014" 
if (strpos("ATA Report of 7th Apr 2014", $date) !== false){ 
//my code......... 

} 

Answer 1

您需要將它們循環。

<?php 
$arr=array("ATA Report of 7th Apr 2014", "ATA Report of 17th Apr 2014", "ATA Report of 27th Apr 2014"); 
foreach($arr as $k=>$v) 
{ 
    if(strpos($v,"7th Apr 2014") !== false) 
    { 
     echo "The position is $k"; 
     break; 
    } 
} 

此外，您正在以錯誤的方式使用它...乾草堆應該先來，然後是針。
