php - Parse error: syntax error, unexpected T_FUNCTION line 10? -

-

what wrong code? ran code on test server , code worked when upload production server 

parse error: syntax error, unexpected t_function in /hermes/bosweb/web013/b130/ipg.acrsflcom/darayngedbeats/gentest.php on line 10

here code 

$old = "http://darayngedbeats1.s3.amazonaws.com    /mp3/crazymonsta2.mp3?awsaccesskeyid=akiajxa36esclqhcb54q&expires=1297279906& signature=hd36zqe8yetiw6jpwkmcciptits%3d"; //enter key needs converted $search =  array(":","?","=","&","%"); $replace = array("%3a","%3f","%3d","%26","%25");  function search_replace($s,$r,$sql) { $e = '/('.implode('|',array_map('preg_quote', $s)).')/';   $r = array_combine($s,$r);   return preg_replace_callback($e, function($v) use ($s,$r) { return $r[$v[1]];  },$sql); }  echo "<br><br>"; $new = search_replace($search,$replace,$old); echo $new;  ?>

the error caused 

return preg_replace_callback($e, function($v) use ($s,$r) { return $r[$v[1]];  },$sql);

chances you're using php 5.2 or earlier, doesn't support closures. can find out version of php you're using phpinfo().

you'll either need upgrade php 5.3+, or use create_function, or write static function , pass callback.

here's example of last option, using simple class store state of $r:

class my_callback {   public function __construct($s, $r) {     $this->s = $s; $this->r = $r;   }     function callback($v) { return $this->r[$v[1]]; } }  function search_replace($s,$r,$sql) {   $e = '/('.implode('|',array_map('preg_quote', $s)).')/';   $r = array_combine($s,$r);   $c = new my_callback($s, $r);   return preg_replace_callback($e, array($c, 'callback'), $sql); }

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
