# How to create an “infinite” table?

Purpose: if \$ r = 10, builds a 10x10 table, if \$ r = 100 ...

What came up with:

``\$r=10; echo '<TABLE>'; \$x=1; while (\$x<=\$r) { echo '<TR>'; while (\$x<=\$r) { echo '<TD>1</TD>'; \$x++; } echo '</TR>'; \$x++; } echo '</TABLE>';` `

But only the first line is built. Where is the mistake?

• Getting into the first cycle \$ x = 1, then we get into the second cycle. The variable \$ x increases to 10. We exit from the second cycle to the first one already with the value \$ x = 10. We finish the first cycle and we already have \$ x = 11 - Demyan112rv

Damn guys, what kind of shit?

` `while (\$x<=\$r) { // раз \$x<=\$r echo '<TR>'; while (\$x<=\$r) { // два \$x<=\$r echo '<TD>1</TD>'; \$x++;` `

Those. it builds one line correctly, because then it returns to the first cycle and the condition is not met, and the cycle ends. Change the variables in the second cycle

` `\$r=10; \$x=1; echo '<TABLE>'; while (\$x<=\$r) { echo '<TR>'; while (\$xx<=\$r) { echo '<TD>1</TD>'; \$xx++; } echo '</TR>'; \$x++; } echo '</TABLE>';` `

Suppose so. And happiness is guaranteed!

` `\$r=10; echo '<TABLE>'; \$x=1; \$y=1; while (\$x<=\$r) { echo '<TR>'; while (\$y<=\$r) { echo '<TD>1</TD>'; \$y++; } echo '</TR>'; \$x++; } echo '</TABLE>';` `
• works, thank you - Andrew Stifurak

Less cycles - less flexibility, but an empty table can be created.

` `\$r = 10; \$tds = str_repeat('<td> поле </td>', \$r); \$trs = str_repeat("<tr> \$tds </tr>", \$r); \$table = "<table> \$trs </table>"; echo \$table;` `
