I have a string as shown below
$string1="then & add â...“ to"; The special ascii characters â “ Â etc. causing errors.
So i want to know there is any default function or ways to remove such characters?
expected output after processing :
$string1="then & add … to"; 
$str = 'aAÂ'; $str = preg_replace('/[[:^print:]]/', '', $str); This is the solution i wanted. Thanks everybody for ur attempts for help me. remove non-ascii characters from string in php
You will need mb_string installed and enabled in php.ini (which it is by default now). On centos install the php-mbstring package and restart the web server, if running via web.
<?php $string = "aâ"; print $string . "\n"; $length = mb_strlen( $string ); $index = 0; $output = ''; while( $index < $length ) { $char = $string[$index]; if( mb_check_encoding( $char, 'ASCII') ) { $output .= $string[$index]; } $index++; } print $output . "\n"; ?> Result:
aâ a For replacing the character with underscore, you can modify the code to append '_' to the string if check encoding does not return 1.
...? There is a special character that represents ellipses, but I don't know if that's what you mean or just showing "other characters go here".
