A non well formed numeric value encountered=>

From the word surface to understand, you can probably spy on some meaning: met the formation is not very good value;

OK, we suspect that one of the parameter types is wrong, that it needs to pass in a numeric type and actually possibly a string.

------------------------@ Chenwei ----------------------------------

So, to solve this problem first to see your custom function, the parameter type passed in and the actual use is consistent.

Such as:boolimagecopymerge (resource $DST _im , resource $SRC _im , int $DST _x , int $DST _y , int $SRC _x , int $SRC _y , int $SRC _w , int $SRC _h , int $pct );

< Span class= "type" >< Span class= "Methodparam" > < Span class= "type" > Several of the specified position and width of the parameters are int (integer), if accidentally passed with the ' PX ' unit, then the error.

< Span class= "type" >< Span class= "Methodparam" > < Span class= "type" >--------------------------------------------------------------------------------------------- ---

< Span class= "type" >< Span class= "Methodparam" > < Span class= "type" > You can have several ways to manipulate data before passing in, such as:

< Span class= "type" >< Span class= "Methodparam" > < Span class= "type" > $str = ' 1px ';

< Span class= "type" >< Span class= "Methodparam" > <　　 Span class= "type" >echo intval ($STR); 1

< Span class= "type" >< Span class= "Methodparam" > < Span class= "type" >echo RTrim ($str, ' px '); 1
