Summary<\/strong>: in this tutorial, you will learn how to use the PHP break<\/code> statement to end the execution of the current for<\/code>, do...while<\/code>, while<\/code> and switch<\/code> statements.<\/p>\n\n\n\n

Introduction to the PHP break statement. #<\/a><\/h2>\n\n\n\n

The break<\/code> statement terminates the execution of the current for<\/a><\/code>, do...while<\/a><\/code>, while<\/a><\/code>, or switch<\/code> <\/a>statement. This tutorial focuses on how to use the break statement with the loops.<\/p>\n\n\n\n

Typically, you use the break<\/code> statement with the if<\/a><\/code> statement that specifies the condition for the terminating loop:<\/p>\n\n\n

if<\/span> (condition) {\n    break<\/span>;\n}<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
The break<\/code> statement accepts an optional number that specifies the number of nested enclosing structures to be broken out of. <\/p>\n\n\n\n
If you don’t specify the optional number, it defaults to 1<\/code>. In this case, the break<\/code> statement only terminates the immediate enclosing structure.<\/p>\n\n\n\n
Using PHP break statement in a for loop #<\/a><\/h2>\n\n\n\n
The following example illustrates how to use the break<\/code> statement in a for<\/code> loop:<\/p>\n\n\n
<?php<\/span>\n\n\nfor<\/span> ($i = 0<\/span>; $i < 10<\/span>; $i++) {\n\tif<\/span> ($i === 5<\/span>) {\n\t\tbreak<\/span>;\n\t}\n\techo<\/span> \"$i\\n\"<\/span>;\n}<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
0<\/span>\n1<\/span>\n2<\/span>\n3<\/span>\n4<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
The for<\/code> statement would execute 10 times from 0 to 9. However, when the $i<\/code> variable reaches 5<\/code>, the break<\/code> statement ends the loop immediately. The control is passed to the statement after the for<\/code> statement.<\/p>\n\n\n\n
Using PHP break statement in a do…while loop #<\/a><\/h2>\n\n\n\n
The following example illustrates how to use the break<\/code> statement inside a do...while<\/code> loop:<\/p>\n\n\n
<?php<\/span>\n\n$j = 0<\/span>;\ndo<\/span> {\n\tif<\/span> ($j === 5<\/span>) {\n\t\tbreak<\/span>;\n\t}\n\techo<\/span> \"$j\\n\"<\/span>;\n\t$j++;\n} while<\/span> ($j <= 10<\/span>);<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
0<\/span>\n1<\/span>\n2<\/span>\n3<\/span>\n4<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
In this example, the do-while<\/code> loop executes only five iterations. The variable $j<\/code> is increased by one in each iteration. When the $j<\/code> variable reaches 5<\/code>, the break<\/code> statement terminates the loop immediately.<\/p>\n\n\n\n
Using PHP break statement in a while loop #<\/a><\/h2>\n\n\n\n
The following example shows how to use the break<\/code> statement in a while<\/code> loop:<\/p>\n\n\n
$k = 0<\/span>;\nwhile<\/span> ($k <= 10<\/span>) {\n\tif<\/span> ($k === 5<\/span>) {\n\t\tbreak<\/span>;\n\t}\n\techo<\/span> \"$k\\n\"<\/span>;\n\t$k++;\n}<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
0<\/span>\n1<\/span>\n2<\/span>\n3<\/span>\n4<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
This example also displays five numbers from 0<\/code> to 4<\/code>. In each iteration, the variable $k<\/code> is increased by one. <\/p>\n\n\n\n
The break<\/code> statement terminates the loop immediately when the $k<\/code> variable reaches 5<\/code>.<\/p>\n\n\n\n
Using break statement to jump out of a nested loop #<\/a><\/h2>\n\n\n\n
The following example illustrates how to use the break statement to break of out a nested loop:<\/p>\n\n\n
<?php<\/span>\n\n$i = 0<\/span>;\n$j = 0<\/span>;\nfor<\/span> ($i = 0<\/span>; $i < 5<\/span>; $i++) {\n\tfor<\/span> ($j = 0<\/span>; $j < 3<\/span>; $j++) {\n\t\tif<\/span> ($i === 3<\/span>) {\n\t\t\tbreak<\/span> 2<\/span>;\n\t\t}\n\t\techo<\/span> \"($i, $j)\\n\"<\/span>;\n\t}\n}<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
(0<\/span>, 0<\/span>)\n(0<\/span>, 1<\/span>)\n(0<\/span>, 2<\/span>)\n(1<\/span>, 0<\/span>)\n(1<\/span>, 1<\/span>)\n(1<\/span>, 2<\/span>)\n(2<\/span>, 0<\/span>)\n(2<\/span>, 1<\/span>)\n(2<\/span>, 2<\/span>)<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
In this example, when the variable $i<\/code> reaches 3<\/code>, the break<\/code> statement terminates the inner and outer loops immediately. <\/p>\n\n\n\n
By default, the break<\/code> statement only ends the enclosing loop. But in this example, we use the number 2 in the break statement; therefore, it terminates both inner and outer loops.<\/p>\n\n\n\n
If you remove the number 2, you will see a different output:<\/p>\n\n\n
<?php<\/span>\n\n$i = 0<\/span>;\n$j = 0<\/span>;\nfor<\/span> ($i = 0<\/span>; $i < 5<\/span>; $i++) {\n\tfor<\/span> ($j = 0<\/span>; $j < 3<\/span>; $j++) {\n\t\tif<\/span> ($i === 3<\/span>) {\n\t\t\tbreak<\/span>;\n\t\t}\n\t\techo<\/span> \"($i, $j)\\n\"<\/span>;\n\t}\n}<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
(0<\/span>, 0<\/span>)\n(0<\/span>, 1<\/span>)\n(0<\/span>, 2<\/span>)\n(1<\/span>, 0<\/span>)\n(1<\/span>, 1<\/span>)\n(1<\/span>, 2<\/span>)\n(2<\/span>, 0<\/span>)\n(2<\/span>, 1<\/span>)\n(2<\/span>, 2<\/span>)\n(4<\/span>, 0<\/span>)\n(4<\/span>, 1<\/span>)\n(4<\/span>, 2<\/span>)<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
In this example, the break statement ends the inner loop when $i<\/code> is 3<\/code>.<\/p>\n\n\n\n
