php - Booleon in objects (classes) -

-

this don't understand. if assign variable $bool value true, , later in code change false, variable $bool looses value?

fyi: reassignment of values happening in function in class.

class csvcheck {     function booleonchange () {         echo "<br>";         $bool = true;         echo "1. assignment of booleon: " . $bool ."<br>";         $bool = false;         echo "2. assignment of booleon: " .$bool . "<br>"; // value of $bool lost. why??     } }  $csv = new csvcheck; $csv->booleonchange();

if code executed in browser, see this:

  1. assignment of booleon: 1
  2. assignment of booleon:

if remember correctly, php boolean false converted empty string rather value of 0 believe looking for.

actually looked it, , seems confirm:

php printed boolean value empty, why?

i'm trying code cyclic autocorrelation function in matlab follows: t=0:(n-1); t=t*te; i_alpha=0; tau=-n2*te:te:n2*te; alpha=-1/2:1/n:1/2; ryy_cl=zeros(length(alpha),length(tau)); alpha=alpha/te ind_tau=0; i_alpha=i_alpha+1; k=tau ind_tau=ind_tau+1; if k>0 % ryy_cl(i_alpha,ind_tau)=1/length(sig_bin_syl_mod(1:end- k))*sum((sig_bin_syl_mod(1:end-k)).*sig_bin_syl_mod(k+1:end)).*exp(1i*2*pi*alpha*t(1+k:length(sig_bin_syl_mod(1:end)))); ryy_cl(i_alpha,ind_tau)=(1/n)*sum((sig_bin_syl_mod(1:end-k)).*sig_bin_syl_mod(k+1:end)).*exp(-1i*2*pi*alpha*t(1:end-k)); else ryy_cl(i_alpha,ind_tau)=(1/n)*sum((sig_bin_syl_mod(1-k:end)).*sig_bin_syl_mod(1:end+k)).*exp(-1i*2*pi*alpha*t(1-k:end)); end end end i'm getting errors, , doesn't show expecting. according below formulae, how can fix it? the code provided incomplete, difficult confidently reproduce error. in particular, haven't de...
