PHP - 删除字符串的一部分

Question

I'm new to PHP and I have a problem.

I need delete all chars since a symbol (Sorry for my bad english , i'm from argentina)

I have this text :

 3,94€

And I need the text is as follows:

3,94

I tried this by multiple ways but it didn't work.

There are a few ways you can do this:

Using strpos:

$string = '3,94€';
echo substr($string, 0, strpos($string, '&'));

or using strstr:

// Requires PHP 5.3+ due to the true (before_needle) parameter
$string = '3,94€';
echo strstr($string, '&', true);

or using explode:

// Useful if you need to keep the &#8364 part for later
$string = '3,94€';
list($part_a, $part_b) = explode('&', $string);
echo $part_a;

or using reset:

$string = '3,94€';
echo reset(explode('&', $string));

The best suited in your case would be to use strpos to find the first occurrence of & in the string, and then use substr to return the string from the begining until the value returned by strpos.
