I was trying to achieve stripping off some beginning part from a string using php ltrim function. It works fine until it get a i character after colon : . if it find i after colon it simply ignore the i character. I know it can be done with substr or any other way but I want to know why its happening with trim. For example.
ltrim('mailto:[email protected]','mailto:');
the above function will return [email protected]
but if I put i after colon.. for example
ltrim('mailto:[email protected]','mailto:');
this one will return [email protected]
Can anybody explain what is happening?
The second argument to ltrim is a list of characters to remove from the left side of the string.
If you did
<?php
ltrim('lllliiiiaaaaaatttttt', 'mailto:');
?>
You would get an empty string as the return value.
Try this instead:
<?php
$email = 'mailto:[email protected]';
$fixedEmail = substr($email, 0, 7) == 'mailto:' ? substr($email, 7) : $email;
?>
