使用特定分隔符截断PHP字符串

Question

Good morning,

I need to truncate a string with a specific delimiter character. For example with that string:

myString = 'customname_489494984';

I would like to strip automatically every string parts after "_" (in this case "489494984").

Is there a function in order to truncate the string part after a specific delimiter?

Many thanks!

François

Use a simple combo of substr and strpos:

$myString = 'customname_489494984';
echo substr($myString, 0, strpos($myString, '_'));

BONUS - Wrap it in a custom function:

function truncateStringAfter($string, $delim)
{
    return substr($string, 0, strpos($string, $delim));
}
echo truncateStringAfter('customname_489494984', '_');
