Deprecated: Function ........() is deprecated in ...\xampp..htdocs .....php on line 

 

 

The value of this setting (in latest php versions for e.g. php 5.3.5) may look like below:

error_reporting = E_ALL | E_STRICT

E_STRICT warns about the usage of deprecated functions. If you run an old piece of code on a new/ latest version then, you may get the following error.

Deprecated: Function split() is deprecated in D:\xampp-1.7.4\htdocs \newfile.php on line 5

{split function is deprecated in latest php versions (5.3.0+)}

To avoid this error change the setting as below

error_reporting = E_ALL

 

 

 

 

Strip additional white spaces

 

With UTF8 the “normal” preg_replace doesn’t really work anymore. For some cases we could use the following trick:

$str = utf8_decode($str);
$str = preg_replace('/\s\s+/', ' ', $str);
$str = utf8_encode($str);

A better solution, though, is:

$str = preg_replace('/\s\s+/u', ' ', $str);

With the param “u” it’s compatible with Unicode.

Sort arrays in natural order

$array = array('1.txt', '20.txt', '2.txt', '21.txt');
natsort($array); # sorts by reference (returns boolean $success)

Condition + assignment

If you want to save the extra line for $pos = $this->calcPos()) you need to be aware that extra brackets might be needed. Wrong (if $pos is supposed to hold the position and not the result of the comparison):

if ($pos = $this->calcPos() > 0 && ...) {...}

Correct:

if (($pos = $this->calcPos()) > 0 && $pos < 100) {
    # doSomething
    $pos++;
    # doSomethingElseWithPos
}

Note the extra brackets around $pos. They are necessary – otherwise it will assign the result of the operation $this->calcPos()) > 0 (which is a boolean).

Comparison (default and strict)

Since PHP isn’t type safe you should use strict comparison (===) wherever possible. "+010" == "10.0" is TRUE (!) only with "+010" === "10.0" you will get FALSE. This might be expected in this case – usually it’s not, though. So it is not if (strpos($str, 'hello') == 0) {} but if (strpos($str, 'hello') === 0) {}, for example! What happens in the == case? It will return true in 2 cases: If “hello” is not in the string at all or if it is at the very beginning. But we would only want the second case (and therefore need ===).
