Special Characters Function

[The Little Guy]

Is there a function that can search for these types of characters:

 

上海帕特是水泵和阀门的专业的生产商。其产å“通过ä¸æ–­çš„技术改进和更新æ¢ä»£ï¼Œäº§å“如下：

[vicodin]

There is no specific one that does that but you can use preg or ereg and you can make it evaluate the variable and it will let you know true or false if there are any special characters in there.

[DarkWater]

There is no specific one that does that but you can use preg or ereg and you can make it evaluate the variable and it will let you know true or false if there are any special characters in there.

 

Actually, ereg() can't be used on binary data.  Go with preg_match().

[Jeremysr]

Try this regex:

 

if (preg_match('/[^\x20-\x7e]/', $text) {
    // there are special characters in $text
}

 

The character class [^\x20-\x7e] matches all characters with ASCII codes less than 0x20 and greater than 0x7e.
