根据特定字符修剪字符串

Question

I've got a string which goes something like myString__sfsdfsf

All I know is that there is a __ somewhere in the string. Content of the string and number of characters is unknown.

I want to remove the __ and all characters that follow so I am left with just myString. How can I achieve this using PHP?

This can be done in several ways. PHP has lots of string functions. You can pick one depending on your requirements. Here are some ways:

Use substr() and strpos():

$str = 'myString__sfsdfsf';
echo substr($str, 0, strpos($str, '__')); // => myString

Or use strtok():

echo strtok($str, '__'); // => myString

Or, maybe even explode():

echo explode('__', $str)[0]; // => myString
