Today, when using the strstr function in php, it prompted Warning: strstr()[function.strstr]: Empty delimiter is wrong. Later, after repeated searches, I found a solution. Students in need can refer to it.
Warning: strstr() [function.strstr]: Empty delimiter
Very strange, is there something wrong with one of the parameters of the php function strstr?
So I wrote a test example
The code is as follows
| 代码如下 |
复制代码 |
|
$text=”asdfghjklqwertyuiopzxcvbnm”;
//$key=”g”;
//根据php错误提示Empty delimiter,判断应该不会是$text的值出问题,所以故意注释了key值
if(strstr($text, $key)){
echo “found it”;
}else{
echo “not found”;
}
?>
|
|
Copy code
|
|
| $text=”asdfghjklqwertyuiopzxcvbnm”;
//$key=”g”;
//According to the PHP error prompt Empty delimiter, it was judged that there should not be a problem with the value of $text, so the key value was deliberately annotated
if(strstr($text, $key)){
echo “found it”;
}else{
echo “not found”;
}
?>
strstr() did not report an error, so I thought that the $key value might be an empty string "", so I gave it a try.
Sure enough, when strstr($text,""), an error message appears: Warning: strstr() [function.strstr]: Empty delimiter
