PHP » Control Structures » foreach
- Syntax:
- foreach ($array as $element) {
// code using each $element
}
Repeats a block of code for every element in an array.
foreach is a very convenient statement when iterating through an array. It eliminates the need to to manually check the size of an array.
Examples
Code:
<?php
$fruits = array("apple", "banana", "orange");
$words = array("un" => "one",
"deux" => "two",
"trois" => "three");
foreach ($fruits as $fruit) {
print "$fruit ";
}
print "<br>";
// alternative method, equivalent to foreach
for ($i = 0; $i < count($fruits); $i++) {
print "$fruits[$i] ";
}
print "<br><br>";
// with associative arrays
foreach ($words as $key => $value) {
print "$key => $value<br>";
}
?> Output:
apple banana orange
apple banana orange
un => one
deux => two
trois => three Explanation:
foreach loops with both indexed and associative arrays are shown. For comparison, a for loop is also included.
