PHP Warning: imagefontwidth() expects parameter 1 to be long, string given in /home/hidecom/public_html/includes/libs/animatedcaptcha.class.php on line 236 ,272 and 274

and this line236, 272 and 274 error reply

line 236 $y = ($height-imagefontheight($random_font))/2;

line 272 $offset_x += (imagefontwidth($random_font) * $this->font_size / 8) + $this->text_space;

line 274 $offset_x += (imagefontwidth($random_font) * $this->font_size / 8) + ceil($this->text_space * 0.5);

please help me

 

can you post the line that sets the $random_font variable? Without knowing what that is, there's no way to make a suggestion.

 

Yup as jestep said, it seems $random_font has a string length limitation to certain character or either its not being passed into that variable at all... So look into it, try echoing that variable and see what it outputs..

 

I don't think you want to echo or vardump it. If it is a font file, it's going to be a huge mess of characters. Seeing how the variable is set should clear up some of the confusion.

 

so what should I do to overcome this

 

You should post the line that sets $random_font.

 

and this line236, 272 and 274 error reply

line 236 $y = ($height-imagefontheight($random_font))/2;

line 272 $offset_x += (imagefontwidth($random_font) * $this->font_size / 8) + $this->text_space;

line 274 $offset_x += (imagefontwidth($random_font) * $this->font_size / 8) + ceil($this->text_space * 0.5);

 

None of those lines is the one that sets $random_font.

 

Look for:

$random_font = ...something...
