Help Wanted: Open Classifieds 2.0.

71 days

by Chema in Open Classifieds, PHP

Hello Friends,

Since long time a go I’ve been thinking in the future of OC and we need to move forward to grow more ;)

I think right now OC is a great product and is helping a lot of people, more than 100K downloads and thousands of sites running this software are the best indicators.

The biggest problem as development team we’ve been facing is the scalability of the code. This started as an small script with really limited functionality, that I used to learn PHP. Not best practices implemented and lot of technological debt that needs to be paid.

PHP currying – delayed argument binding

119 days

by Chema in PHP

To access a local variable within a callback, use currying (delayed argument binding). For example

function curry($func, $arity) { 
    return create_function('', " 
        \$args = func_get_args(); 
        if(count(\$args) >= $arity) 
            return call_user_func_array('$func', \$args); 
        \$args = var_export(\$args, 1); 
        return create_function('',' 
            \$a = func_get_args(); 
            \$z = ' . \$args . '; 
            \$a = array_merge(\$z,\$a); 
            return call_user_func_array(\'$func\', \$a); 
        '); 
    "); 
} 
 
function sum($a, $b) { 
    return $a + $b; 
} 
 
$sum = curry('sum', 2); 
$plus5 = $sum(5); 
echo $plus5(10); // 15 
 
$map = curry('array_map', 2); 
$toupper = $map('strtoupper'); 
$ary = array('haskell', 'curry',); 
print_r($toupper($ary)); // HASKELL CURRY
