for conditon in php code example
Example 1: for each php
<?php
$arr = array(1, 2, 3, 4);
foreach ($arr as &$value) {
$value = $value * 2;
}
// $arr is now array(2, 4, 6, 8)
// without an unset($value), $value is still a reference to the last item: $arr[3]
foreach ($arr as $key => $value) {
// $arr[3] will be updated with each value from $arr...
echo "{$key} => {$value} ";
print_r($arr);
}
// ...until ultimately the second-to-last value is copied onto the last value
// output:
// 0 => 2 Array ( [0] => 2, [1] => 4, [2] => 6, [3] => 2 )
// 1 => 4 Array ( [0] => 2, [1] => 4, [2] => 6, [3] => 4 )
// 2 => 6 Array ( [0] => 2, [1] => 4, [2] => 6, [3] => 6 )
// 3 => 6 Array ( [0] => 2, [1] => 4, [2] => 6, [3] => 6 )

Example 2: php loops
#Loops
<?php
#loops execute code a set number of times
/*
Types of loops
1-For
2-While
3-Do..while
4 Foreach
*/
# For Loop usually use if you know the number of times it has to execute
# @params -it takes an init, condition, increment
#for($i =0;$i<=11;$i++){
#echo 'Number: '.$i;
#echo '<br>';
#}
#While loop
# @ prams - condition
#$i = 0;
#while($i < 10){
# echo $i;
# echo '<br>';
# $i++;
#}
# Do...while loops
#@prapms - condition
/*$i = 0;
do{
echo $i;
echo '<br>';
$i++;
}
while($i < 10);*/
# Foreach --- is for arrays
# $people = array('Brad', 'Jose', 'William');
# foreach($people as $person){
# echo $person;
# echo '<br>';
# }
$people = array('Tony' => '[email protected]',
'Jose' => '[email protected]','William' => '[email protected]');
foreach($people as $person => $email){
echo $person.': '.$email;
echo '<br>';
}
?>
