PHP只从长字符串中删除一个字母一次？

Question

I need to remove a single character from a string, eg in the text block below I would need to be able to remove ONE of the j's.

djriojnrwadoiaushd

leaving:

driojnrwadoiaushd

Answer 1

You can also use str_relpace with the $count parameter: $str = 'djriojnrwadoiaushd'; echo str_replace('j', '', $str, 1);

Ups, sorry.. my bad.

Here is a real way:

$str = 'djriojnrwadoiaushd';
$pos = strpos( $str, 'j' );
if( $pos !== FALSE )
{
    echo substr_replace( $str, '', $pos, 1 );
}
