Recently I have encountered an issue with my old codes. Those were running just fine earlier. Issue occurs while my server updated its PHP version to 7.2.<\/p>\n
Actually, this is common, with up-gradation to server configurations some old functions get deprecated, and in my case, it was PHP \u201ceach\u201d function.<\/p>\n
With PHP version 7.2 \u201ceach\u201d function got deprecated and hence my old codes throwing warnings.<\/p>\n
I have to modify my codes and replace the use of \u201ceach\u201d with relevant alternatives. Luckily my old codes have a modular structure and most of my logic is bound into some functions, hence I have to change only a few lines of code to remove the warnings.<\/p>\n
Here I am giving some examples of the use of \u201ceach\u201d function and alternative way to replicate them with PHP 7.2 compatible codes.<\/p>\n
(is_array($data)) ? list($data, $params) = each($data) : $params = NULL;<\/p>\n
<\/p>\n
(is_array($data)) ? list($data, $params) = $this->altEach($data) : $params = NULL;<\/p>\n
function altEach(&$data)<\/p>\n
{<\/p>\n
$key = key($data);<\/p>\n
$ret = ($key === null)? false: [$key, current($data), ‘key’ => $key, ‘value’ => current($data)];<\/p>\n
next($data);<\/p>\n
return $ret;<\/p>\n
}<\/p>\n
for(reset($data); $keyvalue = each($data);) {…}<\/p>\n
<\/p>\n
foreach ($data as $key => $val) {<\/p>\n
$keyvalue = [$key, $val];<\/p>\n
}<\/p>\n
$data = array(‘arrayInp’ => array(), ‘intInp’ => 2, ‘otherInp’ => null);<\/p>\n
$output = each($data);<\/p>\n
<\/p>\n
$data = array(‘arrayInp’ => array(), ‘intInp’ => 2, ‘otherInp’ => null);<\/p>\n
$output = [key($data), current($data)];<\/p>\n
$i = 0;<\/p>\n
reset($data);<\/p>\n
while( (list($key, $value) = each($data)) || $i < 30 ) {<\/p>\n
\/\/ your code goes here<\/p>\n
$i++;<\/p>\n
}<\/p>\n
<\/p>\n
reset($data);<\/p>\n
for ($i = 0; $i < 30; $i++) {<\/p>\n
$key = key($data);<\/p>\n
$value = current($data);<\/p>\n
\/\/ your code goes here<\/p>\n
next($data);<\/p>\n
}<\/p>\n
Hope that will help.<\/p>\n","protected":false},"excerpt":{"rendered":"
