mb_stripos()

(PHP 5 >= 5.2.0, PHP 7)

大小写不敏感地查找字符串在另一个字符串中首次出现的位置

说明

mb_stripos(string $haystack,string $needle[,int $offset= 0[,string $encoding= mb_internal_encoding()]]): int

mb_stripos()返回$needle在字符串$haystack中首次出现位置的数值。和mb_strpos()不同的是，mb_stripos()是大小写不敏感的。如果$needle没找到，它将返回FALSE。

参数

$haystack

在这个字符串中查找获取$needle首次出现的位置

$needle

在$haystack中查找这个字符串

$offset

$haystack里开始搜索的位置。如果是负数，就从字符串的尾部开始统计。

$encoding

使用的字符编码名称。如果省略了它，将使用内部字符编码。

返回值

返回字符串$haystack中$needle首次出现位置的数值。如果没有找到$needle，它将返回FALSE。

How works on examples mb_stripos:
First we will watch example on symbols(..?).
<?php
$text = "Look! It's a text! Wow!"; //simple text
$spaceIsHere = mb_stripos($text," "); //you can replace " " on something what you need or want
$text2 = mb_substr($text,$spaceIsHere); //cutting text with $spaceIsHere
print ($text2); 
/* Print will show that result:
" It's a text! Wow!"
Look. That " " wasn't cutted, because mb_substr don't write in var position after " " - he write WHERE is " " in string. */
?>
Also it can work on words, sentences...
Here's one of examples:
<?php
$text = "Look! It's a text! Wow!"; //familiar text, right?)
$afterNeededWord = mb_stripos($text,"text!"); //you can replace "text!" on something else what you need
$text3 = mb_substr($text, $afterNeededWord); //cutting string (it is string? im stupid in that question xD)
print ($text3); 
/* Print will show that result:
"text! Wow!"
Explaining the same. */
?>
I hope it was useful with my "good" English skills. ;D
Have a nice day, coder.
