Sample1
Copy the Code code as follows:
<{$colname |trim}>
What if I use a function like iconv that has three parameters? If written as:
Sample 2
Copy the Code code as follows:
<{$colname |iconv: ' utf-8 ': ' GBK '}>
An error message is displayed when you execute it.
Therefore, the study will find that starting in the Smarty template page of the application function usage, in Smaple 1, trim front $row->colname is actually the first parameter of trim, in the middle with | this symbol string;
That assumes that you want to use a function like Iconv with three parameters, write:
Sample 3
Copy the Code code as follows:
<{' Utf-8 ' |iconv: ' GBK ': $colname}>
That is
Function First Argument | function: Second argument: third argument. The value of colname is converted from utf-8 format to GBK in Sample 3.
The above describes the Smarty manual in the smarty template using PHP functions, including the Smarty manual aspects, I hope that the PHP tutorial interested in a friend helpful.
