Examples of implementation are as follows

Prepare the test function to be used for the plug-in engine.
function Str2str2 ($STR) {
Return '

P label start '. $str. ' P tag end

';
}
function Str3str3 ($STR) {
Return ' B label start '. $str. ' B tag End';

}

Note: In testing three examples, be sure to one test, please comment out the other redundant examples, otherwise you will not see the plug-in engine permission priority of the actual contrast results produce abnormal result!

Example one:
The execution priority of the STR2STR2 function is less than STR3STR3, where the STR3STR3 ($STR) function is executed before the STR2STR2 ($STR) function is performed;
The actual operating process is solved as follows:
$str =STR3STR3 (' This is going to be like all the functions passed in the plug-in parameter here the function STR3STR3 the execution priority is higher than str2str2 ');
$str =str2str2 ($STR);
Echo $str;
/* Output results in the browser to view the HTML source code to get the following content:

P label start b tag start this is going to be like all the functions in the plug-in parameter here function STR3STR3 execution priority higher than STR2STR2 B label end P label End


*/
Addplugin (' Cleantext ', ' str2str2 ', Array (' str ' = = '), 1);
Addplugin (' Cleantext ', ' STR3STR3 ', Array (' str ' = = '), 10);
echo doplugin (' Cleantext ', Array (' str ' = ') which is going to be like all functions passed in the plugin parameter here the function STR3STR3 execution priority higher than str2str2 '));
Example two:
Addplugin (' Cleantext ', ' str2str2 ', Array (' str ' = = '), 10);
Addplugin (' Cleantext ', ' STR3STR3 ', Array (' str ' = = '), 1);
echo doplugin (' Cleantext ', Array (' str ' = ') which is going to be like all functions passed in the plugin parameter here the function STR2STR2 execution priority higher than STR3STR3 '));
/* Run result HTML page source code is as follows:
B label start

P Label start this is going to be like the plug-in all the functions passed in the parameters here function Str2str2 execution priority higher than STR3STR3 p label end

End of the B-tag
*/
Example three:
Addplugin (' Cleantext ', ' str2str2 ', Array (' str ' = = '), 1);
Addplugin (' Cleantext ', ' STR3STR3 ', Array (' str ' = = '), 1);
echo doplugin (' Cleantext ', Array (' str ' + ') when the permission sort value is the same size, the subsequent function permission priority is smaller than the preceding so the first added function first executes, here the function Str3str3 execution priority is less than STR2STR2 ' ));
/* After executing the HTML source code results are as follows:
b label start

P label start when the permission sorting value is the same size, the following function permission priority is smaller than the previous reason to add the first function, where the function Str3str3 execution priority is less than the STR2STR2 p label end

b tag end

echo "";
}
Function Alertstr2 ($str) {
echo $str. ' 1+2 ';
}
Addaction (' Alert ', ' Alertstr ', Array (' str ' = = '), 1);
Addaction (' Alert ', ' ALERTSTR2 ', Array (' str ' = = '), 10);
doAction (' Alert ', Array (' str ' = ' to eject parameters ')); The
