Trying to cut a string off and add '..'

[aebstract]

I've got some ideas on how to approach this but I just can't seem to find the exact tools I am going to need. Just some points in the right direction and some functions that I'll need would be great. Basically if my string is over 20 characters, I want to cut off everything past the 20th character and just add '..' to the end of the string and display the result.

Thanks

function str_limit($str) {
   return (strlen($str) > 20) ? substr($str, 0, 20) .".." : $str);
}

echo str_limit("this is a really really really long string");

[aebstract]

function str_limit($str) {
   return (strlen($str) > 20) ? substr($str, 0, 20) .".." : $str);
}

$partname = str_limit("$partname");

 

Figured this should work but it's returning a white screen. Not getting anything from error reporting

You need to echo out $partname. The function just returns the shorted string. It doesn't echo it.

That doesn't justify my entire page being a blank white, it's a syntax error or something I just am not familiar with that second line and the format it's in so I can't fix it really.

Sorry I had an out of place parenthesis. Corrected.

 

function str_limit($str) {
   return (strlen($str) > 20 ? substr($str, 0, 20) .".." : $str);
}

$partname = str_limit($partname);

Hmm still white paging

[wildteen88]

Why dont you enable display_errors within your php.ini that way you wont get a blank page when an error occurs.

$string = "1 This is a test 2 this is a test 3 this is a test 4 this is a test";

 

$string2 = substr($string,0,20);

echo $string2;

if (strlen($string)>20){echo "...";}

 

 

//result = "1 This is a test 2 t..."

echo substr($string,0,20) . "..";
